Thanks for the memories. My Dad bought one of these when I was in high school so my brother and I could learn to operate on the same type of machine he learned on. I was 17 years old and clearing land with one of these. I miss those old machines.
I have cut many roads in Southern California and moved some huge boulders with one just like that. I owned two of them, a 7-M and a 3-T both exceptionally good machines. I subsequently ran many newer models as well. But for cutting dirt roads, that cable blade was hard to beat. It is far quicker than hydraulic blades in making exceptionally fine adjustments on the fly and you could finish dirt roads almost as well as a motor grader blade could. I loved these two old machines. An interesting point here, I rebuilt the engine on the 7-M and the tolerances on the pistons are in the hundredths instead of thousandths. You can install the pistons with the rings on them without a ring compressor. That is why I think they lasted so long. You could establish oil pressure with the pony motor before you put the start load on the engine, and if correctly done you never experienced a dry start of the diesel motor, thus extending its life.
Wow , one of the few people that can start an old Cat properly, as in run it on full compression to warm the cylinders up before opening up the fuel. Seen one guy on here give his some start fluid and has always done so to get it going. Interesting seeing a lot of old Cats starting on here with great clouds of smoke and misfiring and all, only because they haven't been warmed up properly, they all should go and read the manual properly in starting procedures.
I just love the sound of a CAT engine! What an improvement from the time, I just started off as an apprentice operator in the mid 70's until my retirement in 2011. CAT technology and innovations has unbelievably changed the easy operations of their products and different work applications. I always make sure to plan my time for the next ConExpo in Las Vegas, just to keep up with the new & improved equipments from all of the construction manufacturing companies.
Nice pony motor! The one on the D7 I ran 50 years ago was a real challenge to get started. If not careful it would backfire and knock you off the track head over heels...
What a great video. Just loved it. I do have a 1947 cable blade d7 dozer. Engine rebuilt in 1978, but I've only used it for 50 hours. Thinging about rebuilding it again. Every thing is there. Loved your video, perhaps I can get it going again at age 66. It just sits on the property with sticker bushes growing around it. Very sad.
Beautifull machine if you don't have the blade at the precise height it can be a real challenge to get the trunyons in when you angle the dozer blade almost a two man job ! If you are a real cat Skinner it's no trouble 10 minutes and you are chunking out road again. Thank you for sharing your knowledge and your beautifull machine
Brilliant film. I tried to buy D7 about 20 years ago it was similar to this machine but the deal fell through, and it would have been a great to have picked your brain for information!
He’s very stubborn and hardheaded he doesn’t want to fail in front of the camera. He is very proud of that machine you can tell he wants everything to go right even if it leads to pulled back muscle
Operated a D7 very much like that back early 60s Same size blade areal bear hauling down the road ,had to angle blade for decent clearance. Shure was fun ,I was in my early 21s wild and crazy.
I agree, tracks too tight. Get either broke pins or bent one's and throw a track. I used to run one on the Erie Canal in the 70's to dig out spill areas for the HD 1 hydraulic dredge between Buffalo and Syracuse. Lots of rough work in Summer heat, but good pay!
Well I dont know much at all Unca Pete, but I'd say tightening up your tracks tight enough to play dixie on them is gonna lead you to either broken chains or a track off an idler.....
Come on guys, nobody is perfect. All in all he has a nice old Cat, and didn't tear the pinion up like so many do. It must have a bad set of catches on the sliding pinion because he is holding it in all the while. I hope he got it sold, and some new buyer on the road to using old Cats.
No wonder he is selling it. Get a little age on you, and climbing up and down, bending over, standing on your head and man handling a blade adjustment, can put you in traction. Been there, done that. The rails appear thin and the sprocket tips are kind of sharp. As others have commented, the extra tight tracks look good, for the video, but not a good idea for working.
That is what I learned to operate with 1952 3T 20560 ex USAF with a 5speed instead of a 3speed. The tracks would try to come off the idlers if you ran it that fast. I was told that it was built to patch bomb craters in runways. That is why it was so fast
we had a 1962 d8h-46a the exhaust from the pony motor would blow thru the intake of the diesel engine which would cycle thru the diesel engine and heat it up... but yes on a cold day id just let her spin for awhile with the compression lever off... a truely genius design!
Aí é que você precisa de ver aonde começa a experiência do Mecânico operador Eu já cansei de colocar isso aí você tem que mexer na regulagem superior do braço diagonal da lâmina kkk
This guy knows what he is doing. So many on here show how to start. And not know a Fart about doing it . Like the Man said. Watch the Oil Pressure ! ! ! . It never will start. Unless there's Oil Pressure.
Tired of seeing people screw of the starting procedure on these pony motor diesel engines. For a cold engine, start pony motor and let it run all by itself until it warms the head up. Then engage the pony motor to start turning diesel over until it has oil pressure. Once it has oil pressure, give it some diesel, once you see it start smoking close the compression release. Shut pony motor off along with gas supply. Everyone seems to be in a hurry to start turning the diesel engine over, it does not do either engine any good to sit there and turn over waiting on it to warm up. If you try to start it too soon, it runs like shit. For engines that run on gas first, let the engine warm up prior to giving it diesel, if you don't wait on it to warm up your just making things hard on it and you.
My old man had one just like it. Brings back so many memories!!!! Thanks for the video.
best old bush logging tractor you will ever find the 3T cat had a great balance and grunt
Iv always been fascinated by these big machines.Love it.
Thanks for the memories. My Dad bought one of these when I was in high school so my brother and I could learn to operate on the same type of machine he learned on. I was 17 years old and clearing land with one of these. I miss those old machines.
Roll one of these back of the days Indio California
Sure remember those days, pup gas moter to start the main diesel, blade gravity down, no booster cables amazing when hydronic came to town lol

I worked with them for 17 years!!!...
Best pony motor start ever 👍👍🇺🇸
Amazing. Both the pony engine and the main diesel engine starts right away. It sure is in good shape.
Wow , one of the few people that can start an old Cat properly, as in run it on full compression to warm the cylinders up before opening up the fuel.

Love seeing you keeping the old iron alive and well. You not only had to know what you were doing but be careful as well. That thing will bite.
Thank you for passing the knowledge on to another generation on how to take care of and run an icon!!

I started on of these when I was 11 yrs. old. Cranked., No problem. Thanks!
Nice pony motor! The one on the D7 I ran 50 years ago was a real challenge to get started. If not careful it would backfire and knock you off the track head over heels...
Lyle that's exactly what happened to me one morning when my father told me to get her going lol good ol memories huh
Impressive I never even heard of a pony motor that was so interesting love watching a pro who knows his shit
What a great video. Just loved it. I do have a 1947 cable blade d7 dozer. Engine rebuilt in 1978, but I've only used it for 50 hours. Thinging about rebuilding it again. Every thing is there.

If your engine is free you probably do not need a rebuild. Just change your fluids and grease it up and see what happens
What a great video of a guy checking out his nice old Cat D7 and then firing it up!
Great video - very knowledgable chap
It nice to look back on the past and get and understanding of the crawler
Great video! Pony motor is very-cooperative on start-up...! 1970's for me on same-age D8, 2U10000...!
Beautifull machine if you don't have the blade at the precise height it can be a real challenge to get the trunyons in when you angle the dozer blade almost a two man job !

Thank you for posting
Looks to me like that man knows his machine pretty well.
Great vid, l've got an old British crawler - Fowler VF.
Thanks for posting this up, can see your passion for the Cat :)
I really enjoyed this! Thanks!
Brilliant film. I tried to buy D7 about 20 years ago it was similar to this machine but the deal fell through, and it would have been a great to have picked your brain for information!
Love your Cat, I have a few hours on a 3T myself but I have to say that your tracks look really tight!
Nice!!!!( very educational!! Thank You!!)
The army had some of these that had very
Little use.
What a thing of beauty!!
He’s very stubborn and hardheaded he doesn’t want to fail in front of the camera. He is very proud of that machine you can tell he wants everything to go right even if it leads to pulled back muscle
Good job Pete! Nice tractor!
Operated a D7 very much like that back early 60s Same size blade areal bear hauling down the road ,had to angle blade for decent clearance. Shure was fun ,I was in my early 21s wild and crazy.
Thanks for the video Pete, I'm going to try to fire up a 3T and this was a big help.
"no tools necessary ..." just a lot of fuking round .
That new breed of heavy equipment operators would poop their drawers if thats what was needed to be done now. Lol.
They'd be asking where the ac and cup holder are lol 😂
Very informative. Thank you.
Definitely you found yourself a peach low hours corps machine. Well done! Hearing protection highly suggested, lol!
Nvr shut off the poney.
I agree, tracks too tight. Get either broke pins or bent one's and throw a track. I used to run one on the Erie Canal in the 70's to dig out spill areas for the HD 1 hydraulic dredge between Buffalo and Syracuse. Lots of rough work in Summer heat, but good pay!
Beautiful machine, was hoping to see it make some more noise pushing dirt.
Runs nice
Would have to start our D7 3T by rolling it down a hill do to pony motor not working, beautiful old dozers. Very good video
Hillbilly Sniper
Well I dont know much at all Unca Pete, but I'd say tightening up your tracks tight enough to play dixie on them is gonna lead you to either broken chains or a track off an idler.....
that’s all I could see they are about to snap LOL
Back when you actually had to know what you were doing. Not like the premadonna operators today. They turn a key and think they can run equipment
No tools needed, the hernia is free though 😀
Nice machine.
Come on guys, nobody is perfect. All in all he has a nice old Cat, and didn't tear the pinion up like so many do. It must have a bad set of catches on the sliding pinion because he is holding it in all the while. I hope he got it sold, and some new buyer on the road to using old Cats.
A cable blade this size is very handy indeed.
No wonder he is selling it. Get a little age on you, and climbing up and down, bending over, standing on your head and man handling a blade adjustment, can put you in traction. Been there, done that. The rails appear thin and the sprocket tips are kind of sharp. As others have commented, the extra tight tracks look good, for the video, but not a good idea for working.

I used to know an Art Tohill from Tarkio MO. several years ago. Could you be him by any chance?
NICE!
Why does it sound like the camera operator is on an old rickety boat
Nice machine. Are the tracks too tight. I'm not an expert. Just a friendly observation. Love the old iron.
Good old dozers ,yeah tracks way to tight
Hydraulic rules! lol Armchair comfort. Now I’m deaf. 🙁
Great machine but like a few others said, if it was cold the pony should probably be let run for a little while longer, great video
we had a 1962 d8h-46a the exhaust from the pony motor would blow thru the intake of the diesel engine which would cycle thru the diesel engine and heat it up... but yes on a cold day id just let her spin for awhile with the compression lever off... a truely genius design!
hate tell you but that blade was designed for pipeline work back filling the ditch after the line was laid and for clea ring right of way
Tracks are pretty tight.
My 1956 D7 17A has only 3500 engine hours its an ex millitary machine
Aí é que você precisa de ver aonde começa a experiência do Mecânico operador Eu já cansei de colocar isso aí você tem que mexer na regulagem superior do braço diagonal da lâmina kkk
Very sweet, I will send you my address so you can deliver it.
wow,the pony motor makes a lot of force when the main engine has again his compression ,previously to start.
is the cat available still
If you leave gobblers knob hungry it is your own dam fault.
Loosening the turnbuckle on left side was why u had trouble angleling ur blade
Yep exactly. Should've loosened the turn buckle a couple of turns
Yup that’s where I screwed up
This guy knows what he is doing. So many on here show how to start. And not know a Fart about doing it . Like the Man said. Watch the Oil Pressure ! ! ! . It never will start. Unless there's Oil Pressure.
Your tracks too tight.
Tight tracks….
Original means from new not reproductions!
Have a canadian army d7 17 a 3200 hours on it
Uncle Pete needs a larger hat. Just sayin.
UNcle pete I want one caterpila D6 please send it to puerto rico can you ?
No🔧tools necessary to change the blade angle,just need the 💪 strength of GOD to move it with.
Looking for steering clutch parts fo my 17 a
I imagine once you got it running you left it run for the day. You didn't shut it off and start it for the fun of it.
Joli bulldozer,domage que le caméraman donne le mal de mer

Close compression first. Let run. Then give deisel.
Don't watch it then, So many doers. Say this, do that yet never has any videos to show how it's done.
@@BulletBait197031 Malcom Goodwin got the sequence wrong anyway! Lol!
If you use the pony motor to heat up the main engine than why not heat up the pony engine?
Whats the price
Already sold
Стадинец 100 вот оказываеться откуда его скопировали.
An interesting story ruined by hopeless filming & sound. TIP -- check you have camera technique nailed before making entire video.
ALL THAT GOD DAMN CAMERA POPIN' HURTS MY EARS DON'T DO THAT SHIT NEXT TIME!
The sound sucks, can’t watch!
Great dozer. Fire the audio guy.
The BWOSTON accent is as bad as a robot voice.
