- This is the startup sequence for most Cat D2 and D4 tractors equipped with a starting engine. I used my 5U series Cat D2 to demonstrate the procedure.

Thank you for this video. I have a D-2 that was my dad’s. It’s parked inside my tractor shed. It hasn’t been run since the early 1990s.
I’m working on getting the pony motor operational. The magneto had no spark, so a buddy of mine got it working for me. Next I have to take a look at the carburetor.
When I was a little kid in the 1970s we had a Cat 955 high lift.
My dad used to let me drive it around the farm when I was 9 or 10 years old.
You did that exactly right! I’m a retired Cat mechanic of 50 years and even back in the day, customers would tear up the pinion and ring gear because they didn’t understand the pinion brake and clutch mechanism. I also noticed you gave the pinion just a touch of clutch to get the pinion and ring gear teeth to align. Also have to compliment you on the restoration and paint “correct period color” job. Looks like a 44 hyd. Control on the front as well...brings back many good memories👍👍👍☝️
wonderful period knowledge ~ complimént!!
Wow, real old school involved sequence, requiring actual knowledge of the operator. I like that.
Im restoring a 1949 D4 crawler 7u .Thanks for you knowledge i need all i can get.
Used to love watching my dad start up his D2. His uncle bought it new to have my dad do custom plowing. Made some money and kept his then teenaged nephew out of trouble.
Dad ran that Cat like it was an extension of his body. He, too, was very safety cautious and respectful of the engines.
Great memories!
By far the best D2 video on CZcams. Other people make videos, but they just never seem to understand what viewers are looking for.
My grandfather owned 3J796 and 3J2984SP, and later a 7U D4. All ag tractors and none with electric start on the pony. I’ve skinned a lot of fingers pulling on starting ropes. You have a sharp rig there.
My grandparents lived next to an undeveloped field and one day another old man bought that property. He brought in an old bulldozer to clear the land with, but as far as I know, he never got that old dozer fired. He worked on it every day that summer, and I started going over to talk with him. He was about 70 and his wife would come with him every day. He worked and worked and worked on that machine, just grinding away on the pony motor. I learned a lot from him, asking about how this or that worked while he toiled away. All summer long, that poor pony motor just ground itself and the main motor over and over and over, but never any fire. I eventually moved back home the next winter and I never knew what happened to that old man and his dozer, but I hope he got her running and got his land cleared. I remember him fondly, and seeing videos about old dozers like this remind me of him. :)
That little cat has always been one of my favorite machine from caterpillar!👌😎👍
My father in law had a D2. It was always an adventure to get started.
I don't own one, but I could start one now! Very clear instructions, no BS, and we get to see a bit of the machinery.
See? Not every CZcams video needs to be 10 minutes of some guy rambling on about things nobody cares about (not talking about you, you did a good job).
This video was just posted at Jalopnik in a discussion of early aftermarket car electric starters. Very nicely done.
Very well explained. D47U, father bought it over 50 years ago, we pulled it to start it yesterday, after about a ten year nap.
In the mid 1960's, when I was a toddler living in my native Tulare County, California, my dad made a living for the family by doing farm work for the landlord. Sometimes my dad would take me with him when he went to start up the landlord's tractor or bulldozer. I wish now that I'd asked my dad what make and model the dozer was. All I can remember is that starting It was a multi step process, just like in this video. Watching this brought back fond memories from a half century ago. Thanks for sharing.
It truly is small world. I was raised and still live in Tulare County. I have a lot of fond memories of riding on equipment with my Dad. He did a lot of work all over the County.
EXCELLENT video&thank you. There were still quite a few pony motor started heavy equipment pieces back in the mid 1960s here in Western Wyoming when I broke in. This video brought back lots of memories. The operators in those days could do some amazing things with their equipment. Much respect to them, and to you sir!
Wow. Brings back some military memories. Back in 1963 I was introduced to a cable D-6 dozen with the pony motor. It had a rope pull start. Moved up to a Cable D-8 with a pony motor. The D-8 pulled a cable scraper. Never did feel comfortable with that cable scraper because the cables weren't in the greatest of shape. Went overseas where I operated a cable backhoe. Your hands and feet were always busy on that cable backhoe. On day i spotted a hydraulic excavator being operated by a civilian. I immediately realized that this meant the end of the old cable backhoes.
WOW I am 56 years old I would do this for may Dad when I was 9-10 years old what an awesome memory thank you my Friend...
This is a very good video. Everything is done right beginning with "securing the tractor", transmission shifted into neutral, flywheel clutch engaged, brakes set. I am impressed. I operated machines like this when I was a young man.
Thank you that's the most precise description I've seen yet. Something every man should know how to do. Mentally starting your Pony motor can't get you out of bed in the morning when you can't crank up the big motor for some reason.
Our family farmed in the central valley of California from the 30’s through the 90’s. We had a lot of similar equipment to what you restore. It’s great to be able to see and hear some of the machines thatI grew up around. We had a D4, D6, D8 and D9 Caterpillars. None of them were very new but they looked like some of the ones that you have. We also had several farmall M’s and H’s and since we farmed cotton, even a couple of M cotton pickers. Thanks for making these videos and thanks for the memories ! 👍
One sharp looking old Cat.🤩😍❤
Appreciate the video nicely restored machine. Grew up running 6U D4s and 9U D6 tractors. Still have a 7U with a dozer actually has hydraulic tilt. Also have a field ready D6B it has electric start with a glow plug system. Have moved to articulated wheel tractors in recent years. My dad always cautioned me to neve shut the ignition switch off on the pony motor. He had one that stuck off. Worked for another guy same approach. Ran the carburetors dry left the switch on. Never a problem. Crawler were popular in our area because of the hills we farm up to 50% slopes. Many belted tractors anymore as the steel track machines are almost impossible to find parts for. Direct drive like yours. Most of the 9Us were fitted with oil master clutches newer 4s as well. Thanks for posting a bit late to the dance.
Well done !!
Real nice piece of history there .
Happy to see it all shined up and working just like it rolled out of the dealership!
I heard how these started way back in the 70's but have never seen it till now. Thanks for showing that was cool!
ghhiuggg
The actually came out on the 30s
I have to load one of these next week. Thank you for this excellent tutorial. I might actually look like I know what I'm doing.
Outstanding video!
Thanks so much for posting.
I haven't started a D2 in 20 years but I could smell the smoke watching this. You don't run one of these machines with lasers and instruments but by feel and literally the seat of your pants.
Well executed video and beautiful machine.
Well impressed, nicely restored great looking machine .
Thank you for showing Caterpillar owners the correct way to start these tractors.
Thank you for a clear explanation on how to start the old Cat
I bought an old IH Crawler that was about the same size. I was told it didn't run, and the starting valves were all bad. It was about a 1940 as near as I could tell. I was working my way thru college and selling timber and firewood for some cash to eat. I paid $200.00 for it.
I removed the head and it looked pretty good. One start valve was stuck open, but that was all I could see. I replaces the valve and lapped the rest in. I put it back together, and it started on gas after a little cranking. I was told to let it warm up before kicking it over to diesel, so after the temperature came up, I pushed the lever in.
It was a great moment when that old engine came back to life. I used it to drag all kinds of wood out of my Uncle's place. I was surprised at how much traction the little girl had. Still love to hear them come alive, thanks for posting.
It's in beautiful condition, well done and thanks for sharing :)
What a beautifully restored machine! I watched it several times just to take in the machine!
Thank you Sir! So nice to see that you not only keep your equipment in such wonderful shape, but treat it with the respect and good practice that you do. Excellent fine point on throttle position on startup of the pony, and not killing the pony with the mag, and letting it burn out the gas in the carb. Too many cowboys hit the switch, floor the throttle, then reverse on shutdown. You are a gentleman and a scholar, excellent video.
You explained it very well. I still want to watch it again.
This is a man who knows his machine...beautiful dozer!
The Iron Mistress looks beautiful.
She sounds even better.
Very nice D2 and thanks for showing how to start one the right way sir. HOOAH!!!
Thank you, little bit of a forgotten art!!
excellent restoration of your D2 Cat
Perfect start. Hardly any smoke, that i could see. Those engines must be in fine condition. You've done a good job here.
You did a very good job in the restoration of this CAT.
Good video. I like the way you subtly bump the clutch lever to get the starter gear lined up and engaged. I have a 1949 D2 5U, 70 years old and still pushes dirt.
Thank you for sharing the start up sequence.
I remember as a kid that I hated getting near the engine to start our d2 we had. But DAMN I have some great memories of me riding on dad's lap as he operated the dozer. I sure miss the old girl. I always enjoyed watching dad operate the dozer. Fun times back then.
Wow that d2 is mint buddy. Love it. My old dragline I have to let her run half an hr to get enough heat to start the main
That was fun to watch. Nice D2!
i know nothing of tractors, just started following your channel, that thing is beautiful
Very Very good. you did a great job on how it's done. My grandfather, My Dad, & my uncle Leo taught me the same way. 45 yrs ago.
WoW, sure nice to see this machine all rebuilt and taken good care of. It must be a pride and joy for you. These little machines are not to bad to rebuild. Most parts are easy to handle over a larger machine. It would have been a reasonably nice hobby to rebuild it if you had shop space.
We have a '53 7u here in the Karoo region South Africa. These are beautiful machines. Thanks for sharing.
Absolutely brilliant job well done.
SUPERB and BEAUTIFUL !!! Thank you for sharing.
Thank you for this wonderful video!
Nice job on the restoration, looks factory fresh you should be proud.
What a nice machine, and a easy starting one!
Brings back memories, used to plow with a D4 turbo when I was a 15 year old kid. A very long time ago.
This man knows his stuff, anyone tinkering with these old machines should pay attention. His instructions are exactly correct. I generally find that the use of the starting engine is a lost art. Good stuff, excellent vid..
Yes, this starting video is the only one on CZcams where everything is done correctly.
My grandfather had a 56 d4 brings back good memories
Very well done, your instructions were lucid and well thought out , most of all, I can now look at one for sale and know what the guy is doing when he starts it, Thank you. P.S. Your D 4 looks and sounds showroom fresh.
Super cool, I had no idea what was involved or that it even had a pony motor. Thank you
Just beautiful!!! After all these years it run like a new one. Don’t sell it. Keep in the family for your kids.👏👏👏👏👏🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🥰🥰🍺🍺🍺🍻🍻🍻☮️
That is the coolest dozer I have ever seen. Really well maintained, and runs like a swiss watch I'm sure.
im in aus and i bought one off a guy 1954 D2 with all original parts,paint,manuals,receipt of purchase and its only done 2000hrs
2 Thumbs UP. Your one of the few that's know the Correct way to start the Old Cats 🐈
We had two of these at our high school mining and reclamation program. We tore them down and rebuilt them to use during the summer course. Wish I had one now.
Far different way to start than the TD-18 we had.
yeah, I prefer the international engines that start on gas and switch over to diesel by closing an extra starting valve in the head for each cylinder. Over the years, I've had much fewer problems with those than cat pony motors. Heck, one can even drive around slowly operating on gas if necessary.
It takes a lot of steps to get it going great video keep up the good work.
I seen this being done some 40 years ago and I quite didn't understand the process of what I now know to be the PONY MOTOR. What a nice toy for a young man like me. What a nice sound it makes.
Very nice, great restoration,just like a new one. 😊😊😇
well done. that diesel purring is music to my ears
Thanks for a good overview about starting the D2. My dad had one [maybe a bit older] when I grew up on the farm (and he also had an older D4). The pony motors could be a beast to get started. But your directions about the controls are excellent (esp. the throttle control detents advice). Too much knowledge about these older machines is not being passed on to future generations, I'm afraid (24-volt systems, 12v-positive ground, etc.)
Man this makes me miss my best friend. He was a Master on these diesels. Don
That's one nice looking D2 and probably one of the healthiest running pony motors I heard.
I just come from your latest video about removing the starter engine and wanted to see how they work, this was really interesting, nice video :)
Very well done video ! that's a real nice restored caterpillar !!!
good looking machine!!
That was great! Very informative! Thanks!
Electric-start pony motor!
Must be the Luxury version!
This is the first time I ever saw someone give a damn about the pony motor's condition.
One of the most abused parts of the machines. Bit stupid, when you think about it.
You have a lovely machine there.
Cheers.
A+ for your instructions. I wish I had seen your tutorial before I went to look at a '48 D4. When the seller pulled the starter rope, I pointed out that the main engine was engaged by the fact that the fan blade would also turn. He said that was the only way to start the crawler, otherwise the gears would grind if he attempted to engage after the pony was started. Oil spurted out from the flywheel and the hydraulic pump leaked fluid all over. Too many issues for this dilettante so I passed.
He got the starting engine started with it engage to the diesel?!
That was a ton of help for me thank YOU! You do that well
Nice restore. There's seems like alot of steps to follow to start but I'm sure it's simple once you get the hang of it.
best one yet on the net very nicely done i have a 1927 cat starts on 5 trys same old wires to the plugs lucky i think it works so well
Very good and clear video ! Thanks.
I always liked the pony engine because you never have to worry about battery cables and a dead battery. When I lived on my parents farm in the mid Sixties they owned a John Deere 2010. When the loader was attached to it and if the battery went dead you had to detach the loader from the tractor and then remove the battery from the tractor--both tasks were very testy. There were times when the battery was boosted and new cables attached the tractor still had battery problems. All this happened in Southern Ontario Canada.
Nice clean Cat D2 bulldozer; bright yellow paint. He gives us a clear, step by step how to start the older models with Pony engine.
awesome condition, looks like new!
If preceded by a lot of prep.
Gorgeous Machine. WOW.
Note to future Squatch253. You're going to be building 3 starting engines and modifying the main bearings! Double thrust bearing modification on one of them! Brilliant!
Beautiful Tractor
Really nice old Cat.We had a D-4 with the same starting set up.
Uhhmmm... I all the sudden WANT one now. She’s a beauty!
Very nice how you have took real good care of your CAT other people I see with these they are a wreck.
I'm amazed at the many different ways that people start their cats. like you I start mine in neutral, but clutch disengaged, my choke pull is on top throttle on bottom and I've been cracking the diesel throttle open then in my case pull the compression release lever(your lever is what I commonly see on cats) my cat fires right up. I believe my d4d 6u is built in 1950. it's so good too see people who enjoy and maintain their cats.
I served my apprenticeship with Cat in the UK in 1963, I remember this model well. We used to call the petrol start a "donkey engine".
Awesome video and that bulldozer is a great piece of history 👍👍👍👍👍👍👍
I was a city kid who got to drive one of these in Sandpoint, ID in 1972. I remember they used ether to start the pony.
Brings back memories when I had to do it in the mid 60s
I rebuilt a D5 some years back. This D@ seems to have a hydraulic mod as the D5 had all cables and pullies. Nice looking Cat. Amazing to see how these were started ORIGINALLY cause the one I worked on required two hands, and three feet to get started.
Wow, it's so...clean!
You missed one thing. When checking oil levels check the oil in the injection pump as well. It has its own oil sump but if the shaft seal leaks it will drain in to the crank case
