Came here to say exactly the same thing, knowing without a doubt I wouldn't be the only one. One day, eh? Think my wife would kill me. A small dozer on the other hand....She wants a homestead garden after all. Shhhh, no one tell her you don't need a cat D6. Okay okay fine - an old D2 would be ok I guess. She even called one she saw cute. Think I'm off to the races
Mate,I have operated these trucks for 20 years and trust me they are the most uncomfortable things to drive,they have no real suspension (they do but it's for holding such weight and not comfort) the seat is the only suspension you get. If you drive into a hole that's a foot deep you will get thrown around the cabin even hit your head on the roof,that's if you don't have your seat belt on,and there are times you just jump in and go forgetting the belt.
I’ve worked for a Cat dealer since 1994. I spent many hours fixing and actually did quite a few rebuilds of these good old girls. Thanks for the memories this brings. Tranny oil is definitely not good. Too much water can ruin the clutch discs.
@@amunderdog hard to say. Could be moisture build up from years of sitting, maybe fill cap left open for a few months, top cover gasket gone and winter snow melts in spring gets into case. Ive seen plenty of dozer winches full of milky oil and not due to sinking in water but just top cover gaskets are shot and water migrates in. It doesn’t take a lot of water to cloud oil, the problem is, lots of water will effect any clutch packs that have friction discs made from cellulose based material vs rubber. Water causes them to swell so when you think the clutch pack is not engaged it’s actually still rubbing and contacting. Typically first gear is a rubber based disc and other are more water sensitive.
We bought a new log splitter back in May this year and the damn oil was full of water in a couple months of letting her sit. Weather changed and went from cool to humid in a couple of days. Almost hoopa jooped the damn thing. Fuel had a good bit of water as well,luckily we caught it.
Amazing - not a single gasket or hydraulic leak on the whole thing!!!!!! Here in Aus we would run a CEM engine flush to clear the buildup around the rings, a very good chance that would fix the blowby. I have used that flush in a Toyota 2H diesel engine with 400,000ks, drained 14 litres of oil and goop out of a 10 litre engine!

In other words, you didn't pull that engine and fix everything on that haul truck. You did what was smart and correct investment to get the work you need done!

A little TLC she'll make it to 25K.......I have seen quite a few D-8 listed with close to 50K hours. Might need a couple tires eventually, engine sounds really good, blow by looks "normal" . Someone probably left the fill cap off the tranny or it was stolen and sat quite a while before someone noticed it was missing.
Best thing you can do with it is make sure you run it as much as you can. In other words if you are not going to use it daily, at least start it ,idle it, and move it around a little bit. Will save you money in the long run and it will help you sell it when it is that time. Enjoy your real big toy to work with.

Haha, we picked up a couple of those to finish up a job and send the newer 40 tonners to a new job. One old timer said, 'Boss, I have a rule not to run anything older than me and that pos qualifies". He was about 60.
After looking below at just a glance and seen a short comment by a english teacher, I feel I met my match in witticism an cut to the chase. I am guessing that even though most of these large machines get put to bed wet.... I have to think with that many hours some haven't been as hard as say those gold miners on the Yukon where soft wire is the best they have for cotter pins. If its a liquid then close enough for who we work for. I have worked up there when the famous Tony Beets was a pup or guess what mom, there is a foccell in our yard and it moves. I have only memories of things we did an sometimes they are worse than the trip uncle sam gave me in the late sixties. I mainly spent most of my time in the southeast alaska islands and when something large came... it died there. All those islands where there was mining or logging mostly has the carcuses of dead equipment laying in pits and we called them bone yards as it was where we got our "new to use" part just repurposed for it. Out at Thorne Bay where government subsidized roads to open for public eventually, was muskeg that just didn't have a bottom and we hauled rock into those spots. A dozer gets stuck and started down, they gave a half hearted attempt to get it out and then if not our, let the muskeg have it and build road over it. One crazy spot was known to have got three D8s and something else in it too deep before moving forwards with the road. I think it will last a while this machine that you got as a whole looks fair to me. What would I know though and only thousands of miles away on a computer.... at least it is not a grandmothers basement/LOL
Ran one of those at a coal mine that was converted into a fuel truck beat the shit out of it for three years didn't break once. Heater sux ass but 30 below Wyoming winters are pretty cold.
Drove one much like this in a sandpit.Had mud up to the hubs once and the trick was to keep off the gas and let it chug.Just like an old riverboat pulled real slow,but kept going.
Awesome video sir! Pretty cool with the J Paydirt shoutout. Being from Montana, I've watched him for 3-4 years now. He is a Cat man through and through. The trans fluid sure reminded me of calf scours yellow. Gotta love it.
@@tjlqk3 -No kidding, but the application of off road vs on road causes different ware patterns. In the 25 years of being a heavy equipment mechanic the only time I ever see bearing wear is lack of oil. Ring wear is expedited in the mining/dirt works because of dust injection into the motor. That blow by is nothing compared to what I have seen, and those engines run on for thousands of hours.
Very nice looking haul truck. Looking forward to see what project you have lined up. Don’t forget to check the pumpkins and planetary oil. Thanks for the video.
i work for caterpillar and build and weld up the dump bodies in the UK, its good to see how well these hold up over a time period and the beating they take.
Interesting watching the maintenance on the ol' girl. Sounds good for being tired. Got to watch a crew a few years ago doing roadside maintenance on one of the big belly scraper earth movers - for some reason, they decided to flop it on it's side...
Hello, don't know how you feel about free advice but to get the big windfall moving I would have done two things different. First of all I would have filled the truck with dirt or gravel or something to increase your traction friction ratio. The big difference would be to put your choker or chain on and back up so you can rotate the cable around the base several times (4-5 times) and cause the tree and stump to roll once the cable gets tight. Loggers do this all the time to roll a tree away from the stump. I might not have explained this strategy clearly but I tried. Cheers from Canada.
Thats a niiiiiiiiiiiiiiiiiiiiiiiiiiiiice 6x6. I think it would be worth fixing it up back to very decent specs. This would also increase its value. If it was mine...hell...I'd even give it a fresh coat of paint too!
I think you got a good deal on it, should last a couple thousand hours easy. The next time you need help with the belly pan use your other left hand, a come-a-long.
I don't know anything about heavy machinery. I like how you pointed out "that's the transmission" because I don't know what that could've been. Thanks!
In all those 18 years ive been an hydraulic mechanic/engineer ive never seen a truck so dry and clean around all of the hydraulics, not a single flange is leaking and all the hoses in the frame look really good too. Its not really a POS if you ask me 😂
I have this dilemma that's unclear to me and I want to ask since you sir seem like the correct person to ask. It's just very confusing to search for it online. Do hydraulic cylinder speeds vary, can you make them go faster or slower with a faster flow oil pump? Can the hoses actually limit the flow and the speed of the cylinder and the pump? Theoretically, if you use wider diameter hoses would you be able to achieve more speed? I'm just very curious what's the limiting factor. Do you lose power if you make a cylinder go faster, if that's possible ofcourse. Thank you for your time, I'm only 23 and I'm learning, these things are very interesting to me along with everything related to mechanics.
@@nikola6413, Yes yes and no haha, more oil flow will result in faster movement of the cylinder and also more speed/rpm if you would connect a hydraulic motor. Hoses can be the limiting factor for sure but the size of each hose and connection is always over engineered or rated well over the flow that is needed in that application. Too much restriction in hoses/couplers will turn into heat and create pressure differences which in simple terms just means you will lose pressure from the beginning {the pump} to the (machine/cylinder/whatever) All these things are losses which cost money as you do have to put the power in to the pump but you are not getting all the power out of it. Regulating the oil flow with the pump itself is very common, im not going into all the details but many pumps have a variable flow capabilty which can be controlled in many ways to speed things up or to keep temperatures under control ot even keep the input power (the Amps or KW's contant). So yes, you can make things go faster by flowing more oil out of the pump itself and hoses are very rarely a limiting factor. No, higher speeds dont necessarily mean you lose power because the power you are referring to is probably the way you would describe how strong a cylinder is and thats not exactly how it works. The amount of force a cylinder can put out is a result of the pressure and offcourse the dimensions of the cylinder but that is not relevant in this example. Lets say a cylinder is mounted so it can lift things and lets say it can lift 10 tons at 250 bar pressure This 250 bar is max pressure which get set by a pressure relief valve somewhere in the system. Flowing more oil has nothing to do with pressure, (well it has but thats way to much info haha). it would simply mean it would also move faster as well but still being set at 250 bar it would still lift 10 tons. BUT, there is a catch offcourse, Flowing MORE oil at the same pressures Costs more energie to be put in to the machine so again, more Amps and KW's for the E-motor that drives the pump. Thats why some systems/pumps have variable flow so it can speed things up when there isnt much load on the system and when the load increases the flow gets less and less and the pressure builds up so you can have the best of both worlds.
@@jeroen1914 thank you so much for this detailed explanation, I really appreciate it. I'm gonna read this multiple times to understand it completely and not just memorize it
I've only ever cut down two trees totally by myself. From felling, to limbing, to logging (bucking?) and hauling it all off. But I had to move the trunks off my friend's lawn without murdering his grass & beautiful landscaping etc. So dragging them like you did was out of the question, plus my li'l old 38hp 2wd tractor hasn't got the cojones for it. So, Necessity, southern ingenuity & innovation kicked in, (even though I'm yokel from N.E. England) I made a few wraps around the trunk with a long chain hooked to my tractor. That thing rolled right out of there and didn't leave a mark. Now I have some beautiful White Oak for my woodworking projects, and a happy customer.
Awesome content!! love it when you breathe fresh life into old neglected machines (new oils and filters) being an allround operator in the Logging and earthmoving industries you know how hard these machines work with no mercy given.
I'm a gold prospector so I'll definitely be checking that channel out and subscribing👍 my friends used to work at a local tyre garage and they would repair any tyre. I used to go out and get the wheels with them. Often earth movers. When they got them back they would cut new treads into them and I had a go. It's not hard to do so maybe give it a go and save yourself a fortune. Obviously the perished ones you will have to replace. It's quite therapeutic cutting them.
I really like how you keep things clean while working on your equipment, and how your shop and yard looks. One of the better looking redneck amusement parks I have seen.
Use to play with matchbox cars and tonka trucks and here I am grown up but still young at 23 still into these toys but bigger(I’m automotive certified and work on cars on my own not with a shop but want to get into diesel equipment more now)
drove one of those the entire summer of 1999 in a new landfill cell, brand new machine. loved the jake brake, especially when the dump was not down fully (exhausts through the bed of the dump)(that exhaust is not the original placement) fun truck to drive
Always nice to see such close ups videos of this big machinery, love the mechanics of this monster the moving parts. I loved it. It’s a real work horse.
ik little to nothing about diesels and which engines diesel fans hold in high regards but i think this thing sounds badass when you row through the gears
Man, I wish we had the D series of trucks at work. From my experience(s) you got a case of the condensations in your transmission. And TDTO and equivalent, likes to show condensation. Looks pretty solid to me, but I'm just pixels on the interwebs.
@@KT3406E I agree with your reckoning on the trans oil cooler. Also, if the cooler were at fault, would there not be oil in the coolant as oil is at a higher pressure than coolant?
@@KT3406E just watching the blow by puff pattern, I suspect a single-cylinder fail. It's not puffing on all six. Did you happen to do a compression check during your servicing? Or, and this is a strong possibility, I have no idea what I'm talking about.
We all would like it if you'd post a little more often. Doesn't matter if it's your thousandth Cat overhaul and almost boring to you, it's an adventure to us. Same as Jpaydirt pushing Idaho dirt. Now for some Cutty Sark. Beter than Busch light, IMO.

All those islands where there was mining or logging mostly has the carcuses of dead equipment laying in pits and we called them bone yards as it was where we got our "new to use" part just repurposed for it. Out at Thorne Bay where government subsidized roads to open for public eventually, was muskeg that just didn't have a bottom and we hauled rock into those spots. A dozer gets stuck and started down, they gave a half hearted attempt to get it out and then if not our, let the muskeg have it and build road over it. One crazy spot was known to have got three D8s and something else in it too deep before moving forwards with the road. I think it will last a while this machine that you got as a whole looks fair to me. What would I know though and only thousands of miles away on a computer.... at least it is not a grandmothers basement/LOL
wtf are you talking about
Ran one of those at a coal mine that was converted into a fuel truck beat the shit out of it for three years didn't break once. Heater sux ass but 30 below Wyoming winters are pretty cold.
"I just warmed up the transmission...Oh shit!!!" Just the other day I saw that happen to another youtuber fixing his machines.
Drove one much like this in a sandpit.Had mud up to the hubs once and the trick was to keep off the gas and let it chug.Just like an old riverboat pulled real slow,but kept going.
Didn't think you had enuff barrel there for a bit .
Another great video. Everyone needs a 40T rock truck.
Man I wish you would post more often I enjoy your videos more than almost every other youtuber
You are one of those guys that even when your working on and old wore out piece of equipment you still do outstanding work well done sir
Awesome video sir! Pretty cool with the J Paydirt shoutout. Being from Montana, I've watched him for 3-4 years now. He is a Cat man through and through. The trans fluid sure reminded me of calf scours yellow. Gotta love it.
The blow by is from being a dirt machine…the engines eat dust. Haul trucks/scrapers are notoriously for being hard on engines due to all the dust.
I'm sure he is quite aware of what causes blowby...
@@tjlqk3 -No kidding, but the application of off road vs on road causes different ware patterns. In the 25 years of being a heavy equipment mechanic the only time I ever see bearing wear is lack of oil. Ring wear is expedited in the mining/dirt works because of dust injection into the motor. That blow by is nothing compared to what I have seen, and those engines run on for thousands of hours.
Just finished watching . can't wait to see this truck work and the shenanigans when it stops. Glad to see you back.
That transmission fluid was giving me flashbacks of a bad night of Taco Bell nachos.
Very nice looking haul truck. Looking forward to see what project you have lined up. Don’t forget to check the pumpkins and planetary oil. Thanks for the video.
Yes is old but as long she can finish his job without any broken part or error code that good to me
The sticker repair was F ing awesome! 👍👍
If he crossed out the "CA ENVIRONMENTAL REGULATION" as well, he would have had a double kill.
The way the coolant cap spins is so satisfying
i work for caterpillar and build and weld up the dump bodies in the UK, its good to see how well these hold up over a time period and the beating they take.
Love old Cats run a 928G with a grapple welded to it every day to feed the cows. Old girls got 15,758hrs and 65,000km
Interesting watching the maintenance on the ol' girl. Sounds good for being tired. Got to watch a crew a few years ago doing roadside maintenance on one of the big belly scraper earth movers - for some reason, they decided to flop it on it's side...
Hello, don't know how you feel about free advice but to get the big windfall moving I would have done two things different. First of all I would have filled the truck with dirt or gravel or something to increase your traction friction ratio. The big difference would be to put your choker or chain on and back up so you can rotate the cable around the base several times (4-5 times) and cause the tree and stump to roll once the cable gets tight. Loggers do this all the time to roll a tree away from the stump. I might not have explained this strategy clearly but I tried. Cheers from Canada.
I guess that's why Dad always said to get him a big bucket when he was servicing the transmission. Thank you for another great video!
Looks like urine to me
@@staceytowers9056 I rekon I'd be headed to the clinic if it looked like that.
Having lived by the Amish I understand your saw mill reference. Outstanding job, who wants a milkshake!
Who needs a sports car when you've got one of these. :-D
Thats a niiiiiiiiiiiiiiiiiiiiiiiiiiiiice 6x6. I think it would be worth fixing it up back to very decent specs. This would also increase its value. If it was mine...hell...I'd even give it a fresh coat of paint too!
I think you got a good deal on it, should last a couple thousand hours easy. The next time you need help with the belly pan use your other left hand, a come-a-long.
I don't know anything about heavy machinery. I like how you pointed out "that's the transmission" because I don't know what that could've been. Thanks!
In all those 18 years ive been an hydraulic mechanic/engineer ive never seen a truck so dry and clean around all of the hydraulics, not a single flange is leaking and all the hoses in the frame look really good too.
Its not really a POS if you ask me 😂
I have this dilemma that's unclear to me and I want to ask since you sir seem like the correct person to ask. It's just very confusing to search for it online.
Do hydraulic cylinder speeds vary, can you make them go faster or slower with a faster flow oil pump? Can the hoses actually limit the flow and the speed of the cylinder and the pump? Theoretically, if you use wider diameter hoses would you be able to achieve more speed? I'm just very curious what's the limiting factor. Do you lose power if you make a cylinder go faster, if that's possible ofcourse.
Thank you for your time, I'm only 23 and I'm learning, these things are very interesting to me along with everything related to mechanics.
@@nikola6413,
Yes yes and no haha, more oil flow will result in faster movement of the cylinder and also more speed/rpm if you would connect a hydraulic motor.
Hoses can be the limiting factor for sure but the size of each hose and connection is always over engineered or rated well over the flow that is needed in that application.
Too much restriction in hoses/couplers will turn into heat and create pressure differences which in simple terms just means you will lose pressure from the beginning {the pump} to the (machine/cylinder/whatever)
All these things are losses which cost money as you do have to put the power in to the pump but you are not getting all the power out of it.
Regulating the oil flow with the pump itself is very common, im not going into all the details but many pumps have a variable flow capabilty which can be controlled in many ways to speed things up or to keep temperatures under control ot even keep the input power (the Amps or KW's contant).
So yes, you can make things go faster by flowing more oil out of the pump itself and hoses are very rarely a limiting factor.
No, higher speeds dont necessarily mean you lose power because the power you are referring to is probably the way you would describe how strong a cylinder is and thats not exactly how it works.
The amount of force a cylinder can put out is a result of the pressure and offcourse the dimensions of the cylinder but that is not relevant in this example.
Lets say a cylinder is mounted so it can lift things and lets say it can lift 10 tons at 250 bar pressure
This 250 bar is max pressure which get set by a pressure relief valve somewhere in the system.
Flowing more oil has nothing to do with pressure, (well it has but thats way to much info haha). it would simply mean it would also move faster as well but still being set at 250 bar it would still lift 10 tons.
BUT, there is a catch offcourse, Flowing MORE oil at the same pressures Costs more energie to be put in to the machine so again, more Amps and KW's for the E-motor that drives the pump.
Thats why some systems/pumps have variable flow so it can speed things up when there isnt much load on the system and when the load increases the flow gets less and less and the pressure builds up so you can have the best of both worlds.
@@jeroen1914 thank you so much for this detailed explanation, I really appreciate it.
I'm gonna read this multiple times to understand it completely and not just memorize it
Love the steel cable theft protection of the ignition key. :)
"More hours than an Amish sawmill" 🤣🤣🤣
I've only ever cut down two trees totally by myself. From felling, to limbing, to logging (bucking?) and hauling it all off. But I had to move the trunks off my friend's lawn without murdering his grass & beautiful landscaping etc. So dragging them like you did was out of the question, plus my li'l old 38hp 2wd tractor hasn't got the cojones for it. So, Necessity, southern ingenuity & innovation kicked in, (even though I'm yokel from N.E. England) I made a few wraps around the trunk with a long chain hooked to my tractor. That thing rolled right out of there and didn't leave a mark. Now I have some beautiful White Oak for my woodworking projects, and a happy customer.
Awesome content!! love it when you breathe fresh life into old neglected machines (new oils and filters) being an allround operator in the Logging and earthmoving industries you know how hard these machines work with no mercy given.
Your a bad ass dude would like to call you a friend.. from GA I am, glad we still have folks like you and paydirt entertaining us 🇺🇸
I'm a gold prospector so I'll definitely be checking that channel out and subscribing👍 my friends used to work at a local tyre garage and they would repair any tyre. I used to go out and get the wheels with them. Often earth movers. When they got them back they would cut new treads into them and I had a go. It's not hard to do so maybe give it a go and save yourself a fortune. Obviously the perished ones you will have to replace. It's quite therapeutic cutting them.
Lovely to see that truck. I used to work for DJB of Peterlee England the company that sold articulated trucks to Cat. Thanksd for the video.
Great video! I miss the old 400 trucks. They sounded great.
That bit of blow-by is pretty normal for that Cat engine. You might be surprised what a chain saw can do for you .
Good toy and nice playground. Brings back memories from my childhood.
I really like how you keep things clean while working on your equipment, and how your shop and yard looks. One of the better looking redneck amusement parks I have seen.
The old transmission oil reminds me of lancing some lump jaw on a cow! :)
Everyone: "Hey KT why'd you buy that" KT: "cuz i fucking can"
The one dislike is from a Prius owner
Might have been Greta
Use to play with matchbox cars and tonka trucks and here I am grown up but still young at 23 still into these toys but bigger(I’m automotive certified and work on cars on my own not with a shop but want to get into diesel equipment more now)
i honestly laugh out loud at least 5 times watching ur vids listening to you describe something🤣🤣
enjoy your thanksgiving my friend
drove one of those the entire summer of 1999 in a new landfill cell, brand new machine. loved the jake brake, especially when the dump was not down fully (exhausts through the bed of the dump)(that exhaust is not the original placement)
fun truck to drive
Exhaust is original placement. Heated dump body is an option, they don't all have it.
Always nice to see such close ups videos of this big machinery, love the mechanics of this monster the moving parts. I loved it. It’s a real work horse.
Whaddya sayin'!!?? She's beautiful...in her own way. She'll be good for ya'! Enjoy!
Average Joe buying a old rig might be unwise but as I see this man works on heavy machines so this makes sense .
Brings back memories of the Komatsu rocktruck i ran on a hiway job
ran a Komatsu wa500, was a 96 best loader ive touched.
I love this channel, this Man is a master of his craft!!
ik little to nothing about diesels and which engines diesel fans hold in high regards but i think this thing sounds badass when you row through the gears
Man, I wish we had the D series of trucks at work. From my experience(s) you got a case of the condensations in your transmission. And TDTO and equivalent, likes to show condensation. Looks pretty solid to me, but I'm just pixels on the interwebs.
Hope so. Gonna check on the trans vent when I get time. Only thing I can figure.
@@KT3406E I agree with your reckoning on the trans oil cooler. Also, if the cooler were at fault, would there not be oil in the coolant as oil is at a higher pressure than coolant?
@@KT3406E just watching the blow by puff pattern, I suspect a single-cylinder fail. It's not puffing on all six. Did you happen to do a compression check during your servicing? Or, and this is a strong possibility, I have no idea what I'm talking about.
We all would like it if you'd post a little more often. Doesn't matter if it's your thousandth Cat overhaul and almost boring to you, it's an adventure to us. Same as Jpaydirt pushing Idaho dirt. Now for some Cutty Sark. Beter than Busch light, IMO.
looks like its ready for its next service. the hour meter is just past what the stickers service interval is at.
Our boy got it covered
You got the BEST back yard toys!!
Thanks for making these videos. Always a pleasure to see what your up to.
