The pony motor is used a lot in many farm and industrial applications in the 40's and through into the 60's it shares the same coolant as the big motor so it can warm up the big engine on cold days it also serves to start the big engine ..
The gasoline burning pony motor had another feature,,, The exhaust was routed through the cylinder head of the big diesel so as the pony motor ran and warmed up it preheated the intake air charge for starting the prime mover.,,, a lot more fool proof system than electrically heated glow plugs. many had a compression release so the engine could be cranked to circulate oil and build pressure before the fuel was sent to the combustion chambers to light off. No wonder so many of these are still around.
Yes you are spot on in what you said and that's one big advantage the pony motor has over the direct electric start, being able to spin the main engine over on decompression for a few minutes to get the oil around and some heat in the cylinders before firing up equals a lot less wear on the engine.
Boy does That bring back some memories! I ran an 830 overseas working stockpiles. It was direct electric start but the pony motor reminds me of the 8H's and 6's and 4's that had them. It had a hookup for a hydraulic pan, not a cable job and it had the tilt cushion blade. They were a bear, also with a straight pipe. Also had 290 Clarks. Same setup but with a Cummins engine. Take it to a tractor pull and mess up peoples minds! Keep on lettin' 'er snort!
You must have been running the newer 830MB the with the electric start and hydraulic box?? We have the tilt cushion blade for this one, but usually leave it off as it's more manoeuvrable if we want to take it out on the road!!
It was. I never ran the pan hooked to it. Just using the blade. I rode in one when I first went in in Kansas but never got the chance from then on. I made up for it after I got out though! OUCH!!
Sounds like a plan to me. I never got to try one out. The closest was an 835 compactor with a straight blade about the size of a 7. It was a b ear and a half for a roller.
Remember many years ago seeing the earth movers starting up in a sand quarry near me using the donkey engines (England) to get the big old diesel engines started.
MERCY that 830 sounds almost TOO good! SWEET! If you had the cab, blade and an LeTourneau? cable pan for it, you'd have something that would turn heads like the triple-6! Figured I'd just watch them all again. Hope all is well!
Well that's what they are there for, to give you a fix when you need it...so go right on ahead and help yourself!!! We have a blade for the 830, but no box, a box would be great as that was part of the original package they were using out in Vietnam.
No I would have thought they got rid of them many years ago ,mine came from Germany/Netherlands ,that’s where a few could be found from the USA bases out their. The one I have the owner said that she had seen service in the Vietnam war but not sure?. Just putting clutch back into a 2u D8 today ,then the engine I got running after being stuck for many years ,this old side boom is slowly getting their ,but she has been a real battle for last couple years as it sat outside for about 35 yrs plus ,everything seized up solid.👍
I bought an old ex-military repainted 830MB from a guy up in Montana to strip out a sand pit years ago. It was in pretty good shape and everything worked well but the tractor with dozer blade and bowl turned out to be a hand full for most guys so I wound up running it mostly myself. It had the old CAT D343 with electric start and I paid the guy I bought it from to put an enclosed cab and glass on it. It moved a lot of hard clay and was quite a slope hugging work horse but you don't see many of them around. I thought it was a pretty good old machine and I never needed a push cat behind it.
+Ramjet74 Nice, ours is the 830M pony start, we have the blade for it, unfortunately no box which would have been a rope operated Curtis Wright, but we haven't been able to find one. We haven't done much hard work with it, but it's nice to hear from someone who has. Are you still in the construction game now, do you have any old gear still?
+Bostonpowercat Under the circumstances I am pretty much out of it nowadays and not because I want to be . The box Gregg Tedford in Montana matched to the tractor I had was also hydraulic and worked quite well. It was 18 yards heaped to overflow and very responsive. He no longer deals in them like his dad but you might be able to contact him about gear or even perhaps the guy who got my scraper. I am told they burnt up the 343 and were considering using an adaptor plate to dump in a Cummins. That was years ago and while I do not know if he still has it you might want to contact Roger Shinn with Ben Shinn Trucking at Eddyville, Iowa. In 2003, I roaded the scraper to him from Mount Ayr, Iowa to a limestone rock quarry near Cincinnati, Iowa. Roger may be able to tell you what happened to it after he and his brother Mike got it.
Thanks for the comment 👍 it's even slightly more unusual as in it's not just a scraper tractor, it was specifically built for the military! Have a look at this blog article on our website for a bit more information if your interested bostonpowercat.com/blog/caterpillar-830m Cheers
This is one of a model 830 m that I have operated while I was in job Corp plus the same one my brother operated I joined 4 years later .in Ozark Arkansas year 1978
Thanks for you kind words, much appreciated:-) If you want to see the outcome of someone backing over the golf check out one of our videos of a tank driving over a Polo!!!
Thanks 👍 It was originally produced for and used by the American Army in the Vietnam war, it would have had a blade on the front and a scraper box on the back, they used them to clear areas for make shift runways and level up areas to form bases.
Glad you enjoyed the new video, as for Vietnam history the previous owner said it was in active service in the Vietnam conflict, but unfortunately we haven't been able to verify this yet, but still looking into it.
Sorry, I think that comment was for another one of your videos but still, this is another great video showing some of Cat's great machines (in green) ;)
I guess it was roughly pre-1970's Cats that used this system, after that they went to direct start. All our videos are of Cats with donkey engines, we just love the old stuff :-)
+Shane Daft your definitely right, obviously from operator comfort and performance the new machines are great, but they just have any character about them
Just wondering here, I don't know much about this subject but I am always curious to learn. Upon startup you had a separate engine that started the diesel, is that correct? Is that common, or is it a very large engine type of thing?
Thanks for stopping by, always glad to help someone learn if we know the answer :-) Yes you are correct, there is a small engine known as a pony motor or donkey engine (depending where in the world you are as to which term people prefer for it) which is used to start the main engine. Is it common? Or a large engine type of thing? Well it's not common anymore and I don't think anything you would buy new now would have this setup, but up until approximately the 1970's it's the only way these machines could be started so it was the norm. Battery technology and starters motors weren't great back in the day so direct starting with a starter motor wasn't possible on these big engines especially in colder climates which requires a lot more effort to turn the engine over. Before the electric start of the pony motor was common place the pony motor would have been started by hand using a handle so I guess it's been a progression over the years as electronics and batteries have improved and been able to handle heavier tasks. Hope this all makes sense and has answered your question, any other questions we will be happy to help 👍
JESSE YEARS AGO, ALL CATS HAD PONY ENGINES TO START THE DIESEL...I WAS IN THE ARMY WORKING AT POST ORDNANCE AND WE HAD TWO D-8'S TO MOVE TANKS AROUND...THE PONY RAN ON GASOLINE, AND WAS TWO CYLINDER...YOU WOULD START IT, ENGAGE THE PINOIN GEAR, THEN THE CLUTCH, SPIN THE BIG ENGINE UNTIL THE OIL PRESSURE CAME UP AND THEN OPEN THE INJECTOR PUMP...DON'T KNOW WHAT YEAR THE CATS WERE, THIS WAS IN 1961, THE BIG ENGINE ALSO HAD A COMPRESSION RELEASE, THAT YOU USED WHEN THE WEATHER WAS COLD...
Gawd that ol' bitch sounds pretty!!! They just don't sound that way anymore, it seems? Of course, then again, it COULD-be that I just can't HEAR a motor in the same way anymore, lol!☺
Don't worry there's nothing wrong with your hearing!! Your definitely right, they just don't sound the same these days what with advances in modern technology. Glad you enjoyed 👍👍
I take it it is the more modern stuff you have been around? Pony motor/donkey engine start isn't country specific, it's just the way all the old Cats used to start, with the engines being so big the starter motors and batteries at the time were just not up to the job of spinning them over. Cheers 👍
It's Cat's own engine, a 2 cylinder 4 stroke petrol, 25hp mounted in line with the main engine. I can't remember the cubic capacity off the top of my head, but should be able to dig it out if you wanted it though. Hope this answers your question? Cheers 👍👍
+James Pendergrass they made there own. some are inline on the bigger stuff and small one are horizontal apposed they are meany different set up's some run 2 speed trans as well.
+Josh Muhl i don't think we do have i am a Canadian. one think are fuel is not made to the same standers are you super re finds stuff. so some time they will carbon up fast.

I can nearly smell the smoke coming out of this thing... Love it! :D

+Lewie McNeely The 830 is basicly a 824 being run backwards. The 824 is a wheel dozer. The cab and controls were turned around, along with diffs etc.
Sounds like a plan to me. I never got to try one out. The closest was an 835 compactor with a straight blade about the size of a 7. It was a b ear and a half for a roller.

There's one floating around someplace.
Listening to this makes me wish I could drive one too :)
@@ejolite Don't know if the Army still has them. I got out in almost 73 and a lot has gone on since then of which I NEVER kept track of. God Bless.

That looks like one hell of a fun beast to drive.
Thanks, it certainly is, great fun in the snow to being 4WD!
I saw those 830s when I was in Vietnam during the war, they had a bulldozer blade on the front, they were big machines used to clear jungle.
Top ride! Sounds great too.
Cheers Gregg.
Cheers 👍
reminds me of the ol'mrs...missippi road scraper I ran in the navy back in late 70's
for the longest time I thought this was some sort of log skidder
never would have guessed scraper tractor!
Thanks for the comment 👍 it's even slightly more unusual as in it's not just a scraper tractor, it was specifically built for the military! Have a look at this blog article on our website for a bit more information if your interested bostonpowercat.com/blog/caterpillar-830m
Cheers
Looks like the 'ol machine is enjoying the romp!
+Dean Johnson Thanks 👍
Yes it certainly is enjoying the ride out :-)
Most excellent, loved the sound of that Cat motor, great videos, thanks.
Brutal, this one makes a particularly good noise.
safe to say, with a bit of modifications cat could have entered the agricultural 4wd game with this beast
Yes they certainly could have, and one has to wonder why they never did....
Thanks for saving this old stuff. Like they say, don't build them. .you know
Dude, you got that thing blowin' smoke rings!
Practice makes perfect as they say :-)
Cheers
This is one of a model 830 m that I have operated while I was in job Corp plus the same one my brother operated I joined 4 years later .in Ozark Arkansas year 1978
Great to hear from someone who used to actually use them, cheers 👍
Great toy and best noise on TH-cam!
Love the comment!! Thanks very much 👍👍👍
Great video! HD is so pretty. Hope nobody backs over that little golf. Lol
Thanks for you kind words, much appreciated:-)
If you want to see the outcome of someone backing over the golf check out one of our videos of a tank driving over a Polo!!!
that would make one HELL of a log skidder
Sure lots of people have horse pastures, but how many have dozer pastures! Love it!
Diesel Ramcharger Lol well these old girls still need some exercise just like the horses!! Thanks for your comment :-)
Great looking Caterpillar! What kind of work is it used for?
Thanks 👍 It was originally produced for and used by the American Army in the Vietnam war, it would have had a blade on the front and a scraper box on the back, they used them to clear areas for make shift runways and level up areas to form bases.
That has to be fun to drive!!!!!
Yeah it certainly is, especially in the snow being 4 wheel drive as well !!
What a machine - possibly my favourite video of yours so far! Does she have Vietnam history?
Glad you enjoyed the new video, as for Vietnam history the previous owner said it was in active service in the Vietnam conflict, but unfortunately we haven't been able to verify this yet, but still looking into it.
Nice to see a good Cat Scrapper in proper Cat yellow
The army "green" is the original colour for this machine as it was used by the American army in the Vietnam war 👍
Sorry, I think that comment was for another one of your videos but still, this is another great video showing some of Cat's great machines (in green) ;)
+farmertrg no problems at all, it's nice to see fellow enthusiasts who enjoy this equipment as well.
Cheers
That's the life. Playing with all that heavy equipment every day. Don't get better than that does it
Very nice machine.
Cheers 👍
Nothing is more fun than burning some diesel on a cool morning.
that is cool as hell,i want one!
+Jacob Abbott yeah it is a beast that's for sure, especially good fun in the snow!!
Great video
+caligsi Thanks very much, glad you enjoyed 👍
im 48 and been around cats and komatus since i was born just never seen them till i sen them on youtube
I guess it was roughly pre-1970's Cats that used this system, after that they went to direct start. All our videos are of Cats with donkey engines, we just love the old stuff :-)
I so agree just the newer with the joy stickes take the fun out of operating them but thats just me
+Shane Daft your definitely right, obviously from operator comfort and performance the new machines are great, but they just have any character about them
Nice smoke rings!
Cheers, it's a bit of a beast on startup!!
another nice old machine
Cheers 👍 👍
yeah, i'd be driving that to town....hopefully smashing a Prius or two on the way!
Some guys get ALL the toys.......

that thing is cool
Cheers :-)
Are the pony engines the only way these things can start?
Yeah it is the only way this particular machine will start (pony engine), the later models 830MB had direct electric start.
Awesome Bro!
Cheers! You have been pretty quiet on Instagram recently, hope your keeping well? 👍
+Bostonpowercat Was in Montana for 10 days.. Awesome State Bro!
Ahh so jealous, so many places in the world to see, glad you enjoyed 👍
Dostum egzost ağzıma girdi 😂
It's amazing the technology they had in the Civil War
Gawd that ol' bitch sounds pretty!!! They just don't sound that way anymore, it seems? Of course, then again, it COULD-be that I just can't HEAR a motor in the same way anymore, lol!☺
Don't worry there's nothing wrong with your hearing!! Your definitely right, they just don't sound the same these days what with advances in modern technology. Glad you enjoyed 👍👍
i have never seen a donky motor before my self and i have been around cats all my life may be we dont have them in Australia
I take it it is the more modern stuff you have been around? Pony motor/donkey engine start isn't country specific, it's just the way all the old Cats used to start, with the engines being so big the starter motors and batteries at the time were just not up to the job of spinning them over.
Cheers 👍
Hey there i have been around them all my life as im 48 just dont remember dad ever useing them as hes operated cats and komatus
what's it cost to buy one like this and get it back to the uk thanks
That things are :-) and it does like 60 or 80°
Get out of my way, hell on wheels.
+benzman 113 very true 👍👍
good nice
Alexandre Costa Thanks :-)
I need one to drive on I-4
what's cost to buy one like this 😬
show the dashboard and hand and foot controls
Will try and sort that out when we do a new video, thanks for the suggestion 👍
Phil Rusciano ever hear of the word "please"?
Mack Thompson Cheers :-)
That thing is it oh ringmaster

Why do american have problem with vw clean diesel ? they are at least clean as this old cat diesel engine..
We aren't American either so can't answer that one.
I was hoping to get some americans by these typical american maschines to answer my question - but thanks, i knew that you come from England.
No problems 👍
+Josh Muhl i don't think we do have i am a Canadian. one think are fuel is not made to the same standers are you super re finds stuff. so some time they will carbon up fast.
