On the LH side of the dozer there should be a lever to engage/disengage the clutch for the pony motor. The belt from the P.M. to the starting clutch should be tight all the time. Get that P.M bolted down with the belt tight. Then all you should have to do is throw the clutch lever to roll over the big motor.
I would need pictures of the LH side near the starting clutch area.
Spray ether while turning motor over.
Also, I would get a metal pan with hot charcoal under the oil pan to heat the oil will make the engine turn over faster. Let the oil warm up for about half hour then try to start it. Ether should be sprayed while it is turning over.
Also, make sure there aren’t any flames in the charcoal before putting it under the oil pan.
@@janice8379 you can't get to the pan. There heavy stump plates under the machine. If you ever seen a dozer of any kind.
Diesel Creek has a CZcams channel that has a few videos showing the correct way to start a diesel engine with a pony motor. Scrappy Industries is another channel that deals with starting a diesel engine with a pony motor. The dozer itself although pretty old and well used looks like it’s got some good life left in it and would probably serve you well if you can figure it out.
You get an A for effort Greg! The old engine is probably on the edge of having enough compression to fire. Try to get the wife to spray a good amount of ether in the intake( take the intake filter off so the ether is more effective) have the wife spray it in there while you crank it.
Good luck
Agree....... it was turning over enough to start the white smoke was raw fuel.........either straight in for about 30 seconds while it's turning over
Since you don't know how old the fuel is, drain it and put in a few gallons of fresh. The diesel fan appears to have enough revolutions to fire it. Keep the same pony motor but bolt it down and insure the belt is aligned and tight. Should fire them.
I would install a fuel cut off valve on the pony motor. Look to see if you can find a decompression switch or lever on the cat. If so use it to get the rpm of the fly wheel going really fast. When it is released the energy stored in the fly wheel will help fire it up. If there is a antique or vintage equipment collector or show nearby I would suggest you pay them a visit. Most of the collectors will give you a demonstration on how to start it up properly. I can tell you a few things for certain without having the machine in front of me. Glow plugs will help. Get the engine warm as possible. Make sure you have the throttle at least at half throttle when starting the machine up. The pony motor must be secure. Only spray starter fluid when the engine is turning over. Have a wonderful day. It is a pleasure watching your channel.
The throttle was all the way forward. That equals off. Pull it back half way and that thing will start right up....
You need to heat the intake manifold so the engine can have warm air. This helps because the engine has warm air for easier combustion.
Pony motor exhaust is supposed to do that is my understanding.
Fuel in the oil indicates a leaking needle valve in the carburetor. Needs to be cleaned or replaced (probably just cleaned) drain all the oil and replace. Good luck!!
Oil over filled was most likely from the float bowl in the carb and overfilled the crankcase with gas...hense the reason the oil smelled like gas...change that oil out first of all and take the carb apart and clean it thoroughly...mount the gas engine securely and make a lever with a pulley on it inline with the belt so that you can pull the lever and apply the tension to the belt...I agree with other comments for the clutch lever on the other side but don't think you will be able to get the belt tension you need unless you build a frame to mount the motor and use jack bolts to get the belt tight enough
There are a couple of problems with your replacement pony motor setup. The original pony motor was designed to do a couple of things. The exhaust from the pony motor originally was routed through the intake manifold to warm up any incoming diesel fuel to the main engine. The original pony motor was also water cooled and circulated this warm water through the bigger diesel engine. Lastly, the pony motor would turn over the bigger engine through a clutch, bendix and gearbox. It looks like the new setup is only turning the original pony motor over through the original rope start pulley for the pony motor. If all of the original pony motor internal parts are still there, the new setup is having to do a lot of extra work without giving the diesel the benefits of a warm up before trying to start. In one part of your video, the smoke coming out of the diesel indicated that it was almost ready to start and only needed a shot of starting fluid. I’m guessing that the current setup is going to be a warm weather starting machine. The dozer can probably be converted to electric start by entirely removing the original pony motor and installing glow plugs for pre-combustion warm up.
This man pony motors.
Shouldn't there also be a compression release on the diesel motor
Have only seen a couple comments on here from guys that know what is going on and you are one of them. With that pulley system there is no way you will spin the pony motor over fast enough to get the main motor going. Best bet would be to get the Cat pony motor working.
Like was mentioned here, the pony warmed the coolant and the intake for the big diesel. The pony motor also had a high governor speed, they screamed!
I used to have a dozer with a pony motor set up like yours and you can get it to work ok. You were getting close in this video as evidenced by the puffs of smoke out of the exhaust. You should definitely bolt the motor down tight with the belt tight, it would help to use a centrifugal clutch type pulley, that way you can start the pony motor at an idle and then when you crank up the rpm the clutch will kick in and spin the belt. The original Caterpillar instructions say to crank the engine for up to 5 minutes before adding compression/fuel, this was to warm everything up and get oil pressure. Don't be afraid of spinning the motor over for 5 or more minutes especially in cold weather. As mentioned your set up does not warm the fuel or engine water so it is gunna take a bit before it fires.
The design for carbs these days allows the fuel from the fuel tank to drain into the crank case when they sit for long periods. You know it would be impossible to fill the crank case with that much oil. Drain and put in new oil then install fuel shut off valve and make sure you close it off and let engine run until it shuts off after every use. Rotate pull rope assembly, bolt down the pony motor, and I believe I saw an idler tensioner lever on the opposite side. I think it would have started if it wasn’t so cold heat is your friend, try spraying either while diesel is turning over. Love that dog let us know if the shedding is crazy bad..
The pony motor is making oil because fuel is leaking through the carb and into the crankcase. Just shut off the fuel after you get the dozer started.
Aspen is so happy. Typical baby full of energy. They are so happy in the woods. She is a beauty.🤗🤗🤗🤗
The pony motor would work. Needs mounted solid. Needs higher rpm and then a clutch or belt tensioner.
Yes, solid mount for the pony and a pully with with lever to tighten the belt
Check for petcocks on the cylinders to prime them
smaller pully on the pony motor will turn it quicker
Hey Greg! Reach out to Matt@DieselCreek
Him and his buddies tackle these issues a bunch.
My experience has to let that pony turn over that diesel for 2-3 minutes before throwing the coals to it.
Usually will start with out the Ether Bunny when everything is heated up.
Good Luck and Happy New Year to you and yours...
I can remember as a kid in winter hearing the pony motor on the road grader running for 10 or 15 minutes before they would get the diesel engine going. That was back in the 1950's
Read the last step here before trying again.
The pup motor is not the problem. Bolt down the pup motor so you can use the clutch to engage & disengage it. There should be a lever to allow the main engine to turn over faster by opening a valve to allow decompression. Then once it is spinning fast, close the valve. Clean the air filter as well as all fuel filters. Then bleed and prime the pump and injectors. I would add an ether injection fitting into the intake. There are factory ones, but you can make your own too. Heating the intake will also help because warm air is better than cold. Use a heat gun on the intake but try not to burn wires or get any one spot too hot. Bottom line, you need to first make sure you have compression, fuel and air. Timing of the injectors is necessary to make it run after you get it to fire. Make sure you have a way to shut it down via fuel cutoff, or air flow cutoff so it wont runaway.
Much better than my suggestion
If you use diesel fuel that was filled in summertime this might get fuzzy under winter conditions. Could you use fresh diesel with a winterizing Additive?
Greetings Joachim
The original designed pony motor was excellent you also could use glow plugs and a block heater ensure you have good winter fuel with gas line anti freeze that is a good dozer
I agree on the fuel. I have sat for hours trying to get a deisel to go and finally emptied the tank and put in fresh stuff and it turned over right away. Check your fuel first.
Hi, if theres a smell of gas in your oil the cab/ float is not set right,/flooding cab/.
over full oil will past the rings and smoke out the exhaust.
First, bolt the Poney Motor (PM) down, making sure the engine is secured tight and the belt is also tight. As you sit in the dozer, feel down to the left where you found that lever before. That will engage the PM to turn the dozer engine over, but before all that, you need to make sure of other things.
Check the oil dip stick to see if water has gotten in. If there are signs of water, oil will be a milky light brown colour, and the head gasket could be blown, easy fix. Look inside the oil filler cap, too, for the same sign. If the oil is black, that's good.
Next is fuel.
The diesel could be very old. If it is, it will smell a bit like polish. If it were me, I would drain the diesel into a container and use fresh. Don't discard the old diesel as it can still be used once the engine is running properly. You just add a little at a time to the new diesel, about half a gallon to a full tank.
Loosen the injectors and turn the engine over. One of you should turn the engine over while the other inspects the injectors. You can do this on your own with difficulty, but as there are two of you!
If fuel is leaking out of each injector as the engine is turning over, that's good. Tighten the injectors up.
If no fuel is leaking, then there could be an issue with the fuel pump. At which point you need to seek help from someone who knows what they are doing. See what youtubers are in your area who know about diesel engines in particular dozers and ask them to visit you.
Watch your video back. You will see smoke coming out of the exhaust. That, to me, tells me there is hope. What you really need is for someone to give that engine the once over, a full service if you like.
Next up, the undercarriage.
Check the tracks. They look OK on camera, but what about the drive sprockets? What about the track adjustment? If these need replacing, sell the dozer for repair or scrap. Get what you can for it. Take the money and run, just like the person who sold you the dozer in the first place did.
First lesson: When buying any mechanical machine, never, ever trust what the seller tells you. They will lie. They will say anything, just to sell their piece of junk.
Second lesson. Never buy a machine without testing it first. See it running, hear it running, and test it yourself. Try starting it, and if it won't start or there are strange grinding, crunching sounds, then don't buy it.
Third lesson: Always take someone with you who knows what they are talking about and knows what to look out for. If they say don't buy it, then don't buy it. As the expression goes; there are plenty more fish in the sea.
Fourth lesson: Don't buy the first machine you see. Yes, it may be a good buy. Even if your helper, the person who knows what they are doing tells you to buy it, don't! Go check out at least two other possibilities, then go for a cup of coffee and discuss your options.
Last lesson: If possible, look further a field, up to say 100 miles away. Always have options, just in case you return and find someone who has beaten you to it.
Oh, and I never agree to pay the asking price. Haggle a bit, just don't flash that cash. Keep it well hidden until the last moment you hand it over.
Why am I giving you these tips? Well, that's easy because, like you guys, I learnt the hard way.
I purchased a forklift. The seller told me it worked, that it was recently serviced but had just run out of gas. Gas as in gas, not petrol, not diesel and it was late afternoon on a Saturday.
The engine looked like new, heck, the whole forklift looked great, exactly what I was looking for. Apart from the brand new Volvo diesel forklift sat in his workshop. That was a beauty.
The seller agreed to deliver it on Monday because the trailer I had was steadily booked for the following week and i had to drop it off before11am Sunday.
Monday came, and I was so excited. We had been without a forklift for almost two weeks, losing business, then, our replacement arrived.
The guy backed up his trailer into our workshop and rolled the forklift down. I asked why it was nit running but yhe guy said the gas company were backlogged and couldn't delivervuntil Thursday.
It moved easy with two of us giving it a push. Cash was handed over, £12,000 which was the asking price i hastily agreed too. But it didn't matter becsuse we had a new forklift. Well, new to us anyway.
After the guy left and I put the kettle on for a mug of tea for everyone my mechanic looked puzzled and scratched his head.
As I gave everyone their tea he asked me why I had purchased such a piece of junk? What, I asked. He said the engine is knackered and there are parts that are not even connected up.
It was obvious that the seller had duped me. When I looked it was not the same engine! The body was the same alright, same scratches, same dent on the engine cover but definitely not the same engine.
My mechanic did his best for three days. Connected the engine up, tryed getting the engine started but in the end we had to accept the engine was toast.
We reluctantly purchased a replacement reconditioned engine, a diesel engine for £6,000. New hydrolic hozes all round, fittings, even the breaks were knackered so they were overhauled.
There was some electrical work that had to be carried out and two gages replaced. Brand new diesel tank with all the ususl pipes and fittings.
The total amount paid out just to get the forklift working right, £9,389. The total price out of pocket paid in the end was £24,768. Thats 28,784€ or $31,496 or $42,061 Canadian.
I could have purchased an 18 month old reconditioned demonstration model Hyster forklift from the manufacturer with a 3 year guarantee for £31,400. If only I had done my research and not rushed into buying the first forklift I viewed.
I wish you well guys.
I learned a hard lesson, will you?
The original PM had its exhaust plumbed into the intake manifold of the Diesel to preheat the engine It worked like a charm
Great
Alan Clark .A really helpful CZcams to watch is Diesel Creek, He is always buying old equipment, mostly diesels, and getting them running and, showing all the steps he takes. Some of his stuff is as old as yours. Love your vids. Cheers from U K.
The pull start on that pony motor should be adjustable to at least get the rope/handle in the right direction. I know that doesn't do anything to get the bulldozer running but....usually you can remove a couple screws on the pull start housing then turn it and bolt it back on. Quick change that puts the "pull" direction in a convenient place.
Look up " Off-griders " , ( Ambition Strikes ) . They invested in a old Bulldozer that's probably as old as yours and requires a ' Pony motor ' to start it . Happy Trails from Eastern Canada to Western Canada 🇨🇦 ✌ out
CZcams channel Diesel Creek is all you need to learn about old heavy equipment. Matt is an expert machinery mechanic and has a vast collection
First off make sure to cover exhaust when not in use to keep rain out. I'd get the motor bolted down good first and the pulley size does make a difference, smaller on motor for more torque but less rpm's and larger on motor for more rpm's but less turning power. Worse thing for diesel motors is air in fuel system as far as hard starting. Suppose to be able to start pony and then engage it to turn diesel over so get the belt as tight as you can so it doesn't slip. Glow plugs help in cold weather too.
Add a block heater. Even newer engines need help when it is cold.
As someone who follows your channel and comes from the former Yugoslavia, I was pleasantly surprised that you got a dog that is originally from this part of Europe. It is difficult for everyone to pronounce the dog's name correctly, but the most correct pronounce in English is "sharplaneenatz". That dog breed was named after the Shar mountains that separates Serbia from Macedonia. It is true that the Turkish conquerors (Ottomans) brought large sheepdogs with them when they conquered this part of Europe and that some of their dogs probably evolved here into different breed. Greg was probably right (by chance) 🙂
Both of you are doing great work.
Best regards.
Use propane torch to preheat the intake manifold to facilitate starting. I would try hooking up the pony motor to the clutch. I think you will damage the pony motor putting the stress onto the pulley and engine crankshaft. Neat dog!
My impression is that starting a lerge diesel with a pony motor, you shoud have a decompression lever on the diesel - you use the pony motor to get the diesel spinning in the decompressed state, build some oil pressure, get the fuel flowing a bit ... then dump the compression lever and let the momentum of the diesel's flywheel do the starting - not the pony motor.
Hey guys, I just got this off Amazon to fill my tanks on my boat and mower, what a life saver this is, thought you might be interested, well worth the investment and takes all the work out of transfering fuel the old fashioned way. "TERA PUMP 4th Gen TRFA01 Fuel Transfer Pump with Auto-Stop for Over-fill Protection (2.4 GPM) 3 Gas Can Adapters, Long Hose, Hand Fuel Pump for E15, E85, Gas, Diesel - Never Lift Heavy Gas Cans again" I am getting to old to hold heavy cans and fill my tanks and most filler necks now are rigid and you have to push them down to release the fuel, who ever thought of that idea needs to be tared and feathered lol. Hope this helps, love your vids and homestead!!!
I wish I lived closer I grew up with those old buggers. Your right you need a bigger pony the original was gear drive about 16hp so a 13 with a belt tightener lever should do it. You haven't shown the leftside of the motor for the compression release to help starting it.
I've heard of a 'manual' clutch before, but never one that functions even close to the one on your 'dozer. LMAO!
That is remarkable. Whatever works! I think it's awesome! Most guys just fix cars.
Put a block heater and an oil heater in it and plug it in hrs before you want to start it. Also get Katie to spray the either in it while cranking, it stops it from binding up. Your troubles should be over. You can keep it running on ether if you spray across it while its cranking,until it picks up the fuel. Gl
Clean the needle and seat in the pony motor then change the oil. Use a torch of some kind to heat the intake on the diesel motor before cranking it over.
by spraying the starter fluid before cranking it evaporates before being sucked into intake / spray starter fluid as you are cranking and the motor will suck the start fluid into intake before it can evaporate ,,,, try it
the idea of a pony motor was to start in cold weather ,the factory motor would be hoked up to the exhaust manifold to pre heat the air ,let the pony motor turn the big motor over till it warms up
I noticed Aspen immediately in the opening footage. She is a good looking dog and will fit right in with you, all the animals and activity on the homestead. It will be intersting to see how Juniper adjusts to her size, it will be fun to watch them all playing and going on walks with you and Greg. I look forward to all the sage advice from followers enabling Greg to get the Dozer going. It will be fun to see your plans for it unfold as it becomes another useful tool on the property. Have a great week and a blessed 2024. Larry, Central Valley, Ca.
Apply ether while cranking the engine. The way you are doing it , the ether evaporates before you crank the engine.
You need to check for spark , compression, possibly timing , fuel on that pony . You could strap the blue start motor with a tie down strap .
You need to spray starting fluid while its turning over. It was smoking so its trying to start. A magnetic engine heater on the oil pan would help as well
You could bolt the motor down better as there is too much slack in the belt. 😊 when you pulled back it took up the slack and the motor was spinning and it did start it. Good luck you are doing great.
You need to pull the compression release when starting the diesel
Farmcraft 101 (CZcams) is doing a dozer start right now. He's really entertaining while he does it.
You definitely need to heat the motor up whether that’s with an oil pan heat pad or one that goes in the dipstick. It may not be a bad idea to send the injectors out to get rebuilt or just buy new ones depending on the price. If you let it sit for a while, make sure the fuel system is very well bled out of any air.
Went on CZcams to conferm my suspicions. That pony motor is a backyard DIY setup. The drivebelt is connected to the flywheel of the REAL pony motor. The Cat pony motor is watercooled so once you start it and start cranking the main engine over(fuel shut off)it will warm up the main engine making it easier to start when the fuel is turned back on. The way this is set up you are turning over the Cat pony engine AND the main engine and with that pulley system there is no way you can spin everything fast enough to get the main engine going. Get the original Cat pony engine working would make starting a lot easier.
Back in the 70's I built an electric starter motor v belt starter for CAT pony motor. Like you pulling the motor to tighten the belt I had a car starter motor I modified on a pivot. Had a handle attached to the plate to starter motor was attached to which had a push button to activate a starter solenoid. Pull the handle to tighten the belt and push the button to spin the starter motor. Spun it fast enough to easily get the pony started. Your setup should work when you can get enough speed and starter fluid in CAT intake.
Im not an engineer however I watch Ambition Strikes who have a much larger bulldozer but have had similar issues with theirs.
Great idea with the larger diameter pully on pony motor! It seems to be turning the engine pretty well. You might want a little bigger one if it doesn't cause to much drag on the pony motor. A couple people have already said to find a way to tighten the pony motor down with the belt tight, that would help you a lot. I noticed that you would spray the starting fluid, and then take your time trying to start it. Try spaying the starting fluid while you crank the engine. I think you will have better results. heating the intake manifold may help a little. Try to remember you are compensating for an old tired engine. I think you should fix the steering column shifter problem in the Chevy truck! Look on CZcams, there is a bunch on those.
She is a very sweet and pretty puppy.
Chris wanted to agree with the comment about the clutch lever comment. As well add: you should get some heat on that motor.
He’s a HD mechanic. That’s a good place to start.
Hi Aspen! You’ve got a very sweet mask ❤
You need spray the starter fluid in the intake when the engine is turning over, and tighten the belt.
I don't know about the D4,but larger cat diesels have a compression release. This must be closed before the diesel will start. The pony motor was designed for the exhaust was routed through the exhaust manifold to warm the engine before disengaging the compression release.
Get a couple of fuel transfer pumps, one for gas and one for diesel. The new fuel can nozzles are crap. Guardian dogs are a great addition to a homestead. Welcome to Aspen. Thanks for the episode.
Oh you are in for a rude awakening having a LGD! The barking, oh the barking........all night long! What a beautiful puppy. We have Great Pyrenees and oh the barking, but we know that comes with most LGDs. Can't wait to follow Aspens progress. Ours is getting up in age and need to consider what breed is next. Best of luck!!
So Sweet Junipur has a new play mate 😊 She is one big puff ball. Love it. Welcome to the family, Aspen.
Amazing what you can fix! Katie you know the transmission is next on the old pickup don’t you. 😮.
Love the pup so cute anyway your motor is big enough but it isn't helping you that it's loose if you can keep the belt tight you should be able to get the pony motor going and pull your handle at the opposite side and give it the sauce 😉at same time but take of main motors air filter and then spray the sauce into engine miigbt work better if your wondering how I know old farmer been there done that many times to many😮
When push things lower is better. Lose so much power by pushing up high. Look at football. All about leverage. Also warm the starting fluid it works best warm.
You defiantly need a bucket over that exhaust when not running. Also you need a way to preheat the engine especially the intake manifold. Carefully with a propane touch is a good way.
You NEED to cover that exhaust pipe when storing the Cat.
Not sure this will help as you have had a number of good directions but take things one step at a time especially when you really don’t know.
Tighten the pony motor so the belts are tight, no slack. Probably now is a good time to replace the belt.
You know the pony motor will start and run but I would replace with an electric start motor of higher power. I know the sequence is wrong, sorry.
Go to harbor freight and get a few welding blankets to tarp the Diesel engine area. Build a fire under the engine as a block heater. If it can be fitted with a heater then that is a better choice. Get a case of starting fluid to keep on hand. Heat will liquify any gelled fuel in the lines. A thought....if you can get a tent of sufficient size get that instead of blankets and super heat inside of tent that you erect over the dozer. It will make working on it much easier. Check that you have fuel in filters and if not, fill with trans fluid for easier starting. Hope this helps and not redundant.
i think your pup motor might have gas in the crankcase hence the over fill of oil mixed with gas the carb may have leaked gas into the crankcase and filling the cylinder also making hard to pull maybe drain the crankcase and fill with fresh oil but also close off the fueline going to the carb untill you are going to use it good luck
Thanks for the very nice video. A high oil level in the pony could indicate water with the oil. If so be by now you have a milk shake. Sincerely hoping the Cat becomes a helpful tool for you. The house exterior looks very nice. The days are getting longer. Ron PTL USA, Next to Canada.
Great video, always fun to watch. You guys work well together.
Keep at the dozer you’ll get it going.
Can’t wait to see that thing running!
The float on the pony motor is probably sticking too
Great video Greg and Katie
Put a tarp covering the engine area and put a heater in there for an hour or 2 to warm the engine up
Your pony motor is close....perhaps a slightly bigger pulley on the pony side to get a faster engine turn. One thing you should first is get the pony motor mounted solid and utilize a lever to tension the belt......I'm sure the dozer has an existing setup for using the pony motor....get that working. If after that doesn't work....perhaps purchasing a larger pony motor. Changing the diesel filter, and purge the lines of old diesel fuel. If the fuel in it is not adequately treated for cold weather, it may be a bit gelled.
Hello family, blessings and happy new year. Since they are puppies, these dogs are accustomed to wearing spike collars so that they can take care of their pack (the animals on the farm) and protect their lives. They are very effective.
Another great video. Welcome to Aspen, what a lovely dog. I used to share a home with a Pyrenean Mountain dog, I’ve no doubt related to these dogs way back when and they are still used today guarding flocks in mountains of France. The dogs are hugely intelligent, incredibly protective of stock and property in addition to being amazing soft family pets. I can see Aspen being the new STAR of ‘This Off Grid Life’. What a great start to 2024.
good morning how are you guys doing today and I like what you guys are doing I guess you guys got a new toy to fix today all right well you guys work on that new toy and hope it works cuz you guys do definitely need it around the property text the property up better all right guys have a great day and God bless you
Pony motors worked well when they were set up and adjusted properly. I have owned 2 older D-4 7U series cats, and they worked well, most of the time. But they could be cantankerous and hard to live with. That's why I recommend going with an electric start crawler dozer. A lot less headache and more time spent working then trying to get the blasted Cat to fire up!
Diesel Creek channel used a hand held gas saw modified with pully and belt.
Getting a LGD is a very smart move, considering where you live.
I had to find the the sight the sight is Pacific Northwest Hillbilly if you want info I would think he could help. Good luck!!
Beautiful pup.
You almost had it the last few times with the pony motor when it started smoking from the exhaust. You didn't let it go long enough. It looks to be hard to keep pressure on the pony motor to keep the belt tight? Can't you use a pry bar to make it easier on you?
You're going to tear up the tractor trying to tow that thing...
Yes, she is adorable and Juniper is so active. That’s good that she has another active dog to play with.
AWESOME puppy!! Can’t wait to see what she will do to scare off a predator!!! Maybe the easiest thing would be to have Katie spray while you are trying to crank. To much time is passing between spraying and starting to turn over. We know it runs when it is started. Good Luck with BOTH endeavors!!❤❤
Greg o have had a bunch of experience with old equipment and in my experience, it is very difficult to start those diesels in the best of circumstances when it's cold. I installed an electric block heater which goes right inline with a coolant hose. If you plug that in for a few hours but will make a world of difference in trying to start it! Good luck! Joe Maiato (RI)
Great video! Hold a junk pillow tightly over the dozer exhaust pipe while cranking. Keeps the unburnt fuel in the cylinder causing it to light off. Need glow plugs in the long run.
These engine did not come with glue plugs, that why they use a pony engine and turn it over longer to heat the inside of the compression chamber.
I didn’t know that, I guess you learned something every day. Thank you. I guess I would resort to using a torch to heat the intake manifold and using the pillow to cover the exhaust if I really needed it to start then.
Aspen is beautiful... good luck on the tractor.
She's a beautiful puppy
Well here goes from a cold climate guy.
As you have found out, starting a diesel in cold climates sucks. Not knowing the specifics of that dozer, but knowing how diesels like to be babied.... You have a great advantage though...NO FRIGGIN' COMPUTERS!!
Heat and cranking RPM are key. The warmer you can get that motor the better whether you devise a way to have it suck in warm air through the air intake, heat the oil using an electric heating element or external source like a pile of coals, warming the coolant with a block heater/hot start or combinations of ways to warm it up. I'm sure you know that your tractor has glow plugs that burn and warm up the air inside the cylinder before you crank it. If your dozer doesn't have those you don't have that advantage, if it does, get them working. Warm is good, especially in the cylinders.
A way that is used here on wood skidders to warm them up in the winter is they have flexible coolant lines with quick connects that mate up to the same on a vehicle. So when you pull up to the skidder, you simply connect your truck's cooling system to the skidder's cooling system and circulate. Use the truck to warm up the stone cold diesel. The warmer you get that motor, the happier it is. 100F is a happy place to start with.
Remember, you've likely got 15W40 oil in that thing, that's a heavy oil and when it gets real cold, it's gonna let you know. You're also turning a hydraulic pump with yep....cold thick hydraulic fluid.
Ether....yeah....it needs to be sucked in as the engine is drawing in air.
As others have said, there should be a lever to engage the pony to your main engine and I think I saw it in one of the left side shots. You shouldn't have to be pulling tension on the pony. I'm sure you are aware that diesels run by compression. Is there a decompression valve on the motor somewhere so you can release the compression to get the motor spinning faster without the resistance of compression, then dump the compression valve so that the fuel will ignite?
As for the overfull pony oil, are you sure it was pure oil? Did it come out real thin? If it was pure oil, then ok, somebody overfilled it. If it came out thin, did it smell like gas? Sometimes the float valve in the carb can get stuck down allowing the needle valve to be open and then gravity takes over if there is no gas shut off or it's left open. The gas from the tank drains to the lowest point, down in to the carb, then in to the head area, then seeps down in to the crank case.
That's a cool machine you've got there.
Hey Greg, I felt if I was there....My extra 60 Pounds of Muscle could have gotten that pony motor working correctly. LOL ha ha.....giggle giggle. =) Congrats on the new Pup.....Cool Stuff.
Yes larger pony motor with some type of clutch or pulley assembly would work on spinning the engine over better. But be prepared on a machine that old for other potential issues. Fuel system, steering clutches, track idlers, leaking hydraulic cylinders, low compression. I don’t want to be a downer and if you like working on machinery could be fun to restore. I don’t know if there is anybody near you that has a dozer you could hire for the day and if they are good at it they could do a lot in a day. Spend your time in what you’re good at.
She is beautiful love her name Aspen. Aspen will become a great addition to the homestead ❤️🇨🇦
Wow , she's beautiful . She's gonna be huge also . Definitely an outside dog also . Just make sure there's no wet snow under her after she lays in the snow for a while .
I used to work on these it seems you are able to get the big engine to turn over first make sure you have clean fuel in it and clean fuel filter then loosen the nuts on the fuel lines at the injector then if if has a fuel primer that will pump the fuel to the injectors use it to prime fuel thur the lines and as the fuel starts to push out the lines tighten the line nuts do this to each line once you have the lines bleed it should start if not give it some either to see if it will start if it does not start try turning engine over and rebelled fuel lines. It should start unless injectors are bad. If it does not start remove injectors and try cleaning them. Fuel in a diesel engine explodes and that is how it starts and runs if you have fuel it should start.
First, you need the smallest possible pulley on that pony motor. This will transfer more power at a slower speed.
Second, you need the proper width/depth of the V-belt. This may be impossible because the pulley on the dozer is likely NOT designed for a V-belt.
Third. If the belt is still slipping, you are going to need double sleeves.
Fourth, you need a better way to hold that pony motor tight. Even a turn buckle arrangement. I kept waiting for you to rip that gas tank off !
Get these things sorted out before buying a larger engine. Unless you you have a need for a 10-15 HP engine for other things.
I was worried you guys got scammed buying that old cat, but looks like some of the comments sound like its maybe an easy fix! I bet that puppy is gonna turn into a BIG dog. Nice going,
I don’t have any suggestions regarding the bulldozer, I’m a registered nurse by profession 😊 but I love your perseverance in trying to fix the issue! I love your new puppy, she will be much bigger. I’m a dog lover by heart. I have two rescues myself, a rat terrier and a chihuahua rat terrier mix. I couldn’t imagine my life without my dogs!
Gregg I see that you have a air cooled engine. Ln cold weather you have to put the exhaust into the diesel exhaust manifold g. There should be a pipe inside to heat the incoming air. It will take some time to get it to go. Put the gear box in low gear and engage the starter pinion to turn the big engine this heats up the engine by making the exhaust hotter. The original engine is water cooled and is plumbed tnto the big engine. The pony engine is a horizontal with center crankshaft and the pistons are on each end.
I hope that helps you.
You may have to put a electric engine heater in the water jacket to get heated water.
Good luck.
Spray starting fluid while you’re cranking it over.
I don't know anything bout dozer, much luck with it and hopefully helpful comments... love the new pup addition. Absolutely adorable ❤. Great playmate for juniper...❤ training seems to be working 🎉 so love watching you guys❤ happy new year to you 🎉🎉 keep sharing we'll keep watching ❤❤
you need to mount motor and put a pulley with a handle on a pivot to pull so it tensions the belt
You could use a weed burger to heat the block first get it up to a decent temperature & maybe invest in the adjustable belts too
Agree with several of the comments below, so don’t give up!!
-in-line fuel shut off on pony motor will stop fuel in oil; change the oil.
-find a way to heat the intake on the cat; exhaust from pony, torch.
-bolt down pony solid and either existing (if any) clutch/pressure release, or build tension pulley/clutch
Diesel Creek is a great channel that might help (Matt is great!).
I admire your perseverance!!! It seemed pretty close to going! Congrats on the new pup, beautiful! Thanks for the video
Aspen is gonna have a huge appetite!
