As a teenager, I used to summer fallow in Alberta with an RD6. I remember that startup process well but what I liked most was the sound when the diesel kicked in and you shut down the pony engine. Also the incredible sound of the engine when it started to pull down.
Wow this brings back memories. My Uncle had a construction company and two of his oldest machines, a grader and a dozer had the pony motor starting system. He trained us rookies on these.
@@clankplusm I don't think that's true. Even back in the day only farmers would know how to start such a machine. Cars already had electric starters and hand cranking was only done in an emergency.
My father used to tell us about operating these old D6s, D7s, D8s, up in Alaska in the early fifties. This is the first time I've actually seen one. Such torque!
Quite common even today. It’s essentially what an auxiliary power unit is in an aircraft (that jet engine you hear when boarding before they actually start the jet engines on pushback).
My grandad had several Caterpillar pony motors running various equipment on the farm. I remember a generator, a backup well pump, even a sawmill. That was the first engine I ever rebuilt as a young teen ( I'm 50) I still have two that run and parts of several other
Grew up driving a Diesel 35 on a wheat farm in Eastern Washington. Our Diesel 35 was almost identical with the RD 6 which several neighbors had.. Broke my arm starting the gasoline starting motor when i was about 14, . Got lots of advice on how to hold the crank afterwards - I was putting my thumb around it instead of cupping it in my hand. I think I ran the gas tank dry and then when I filled it the float stuck flooding the engine and it backfired. That was the only time I had any trouble starting it or the diesel motor. A great video. Appreciate your taking the trouble to put this online.
@@17industries42 Here's a link to crank starting a model T th-cam.com/video/oN-JbmBTOPA/w-d-xo.html The principle is the same as regards hand cranking the RD6. The issue is that if the engine back fires and you're holding the crank wrong, it can break your arm. In a nutshell, you want to hold it in your cupped hand so that if it backfires, it will simply knock your hand away from the handle instead of breaking your arm or thumb.
I suppose that, on the upside, you don't worry about finding a dead battery. On the other hand, you have to get up two hours earlier to get the 'dozer ready for work!
@ Chuck Beef Nope Kids today know how to google shit. It’s actually quite funny because many will come back with primary sources debunking the bullshit you supposedly lived though.
@Carl - any tips on better operating procedure to avoid a broken arm? Would it be better to catch the compression while the starter crank in in an upward motion?
@@stanpatterson5033 pretty small motors with pretty low compression (6 or 7 to 1 ratio) compared to modern engines. wouldn't break your arm, but could put a good bruise on the hand though.
@@stanpatterson5033 Don't wrap your thumb around the handle. Keep it curled around the same direction as the rest of your fingers. That at least prevents your hand from being ripped apart. But that little pony engine is probably only 6-8 horsepower.
I work in a field where I have to make things stupid simple for an operator. Watching this makes me think that we would be in big trouble as the human race if we had to go back to doing things this way. I love this machine by the way! Stuff like this I enjoy for the simple fact of what I have to do in my profession!
Where were you 30 years ago when we had so much trouble starting our old D4? Now I know what we were doing wrong! Too late now, the old cat's been sold. Keep smiling.
Absolutely incredible. So many cool steps. How awesome to build a small motor attached to the big one to start the big one, knowing we're not going to be able to start the big monster.
Before Dad went off to Korea, the 15 was used for the family saw mill. When it was cold, Dad would build a fire under the oil pan to warm the oil - of course made some safety feature to keep things from burning or blowing up. I love this video you made - thank you.
Nice! A neighbor had one of these when I was a kid - except the pony motor was started with a pull rope that you had to wind on each attempt. Brings back memories.
Nice video, I have a 1935 RD6 that was "Restored" in the 90s and it needs some work. The O-ring between the injector pump and the fuel filter housing it leaking and pouring diesel into the block. So once I get that taken care of, i'll start to get it going again.
WOW does this bring back some memories of some of the dozers we had in the Army Engineers. I remember doing this same thing but they were a lot bigger. Thanks for the refresher course...
The compression you're referring to the engine's compression ratio. Compression ratio is a function of combustion chamber volume, so its shape, not stroke or piston size (which is actually the bore diameter). A 1cc engine could have more "compression" than a 1000cc engine; it's all about geometry.
I was operating one of these at 12 years old!! Lucky for my grandpa there was no You tube! I never could get it started when he was at work as an engineer at Northrup Grumman during the week.
Most modded exhausts sound terrible. Like the glass packs on slow V8 trucks or fart canons on Dodge 12v diesel trucks-both of which would probably lose to the Cavalier. 😂🤣
Wow. An oldie but a goodie. Would be nice to have. Funny but starting procedure / levers remind me of a Ford Model T (?).......why not, it was after all built around that time. For this RD6 to have lasted this long, for sure previous owners truly appreciated and maintained it to a large extent. Heck of a machine that RD6!
Looks like the Pony Motor was rebuilt / I'm thinking that as it has a nice coat of Caterpillar yellow paint. Sure is a nicely working tractor. Thanks for the video.
Squatch , thanks for the excellent vid , My dad had two old Rds he intended to get running , but never did , I would play on them as a kid and allways wondered how they operated and sound , wow that is slick!
My old man worked on Caterpillars all his life. Graduated top of his class at the Cat school just after the war. (47 or 48..?) Never once did he call it a pony. Was always a Donkey in our neck of the woods....
It’s very interesting that you mention the F-16. It’s that specific aircraft that actually uses a miniature jet engine as a starter (with its own electric starting system) to start the main jet. It also has a hydrazine turbine auxiliary power unit for emergency power if its engine fails.
Cool video. There certainly is a procedure. I have an International MD that starts on gas and then switches to diesel but without the pony motor. It has "procedures" too. Love those old complicated machines
This excellent demonstration reminds me of a video on the operations required to start the engines of a B-29 Superfortress during WWII. Look it up: ' Boeing B-29 Superfortress Flight Engineer - 1944'
Just watching a few vids before bed and this put a big smile on my face had a buddy living on an old fish boat and it took two of us to start the BIG 6 cylinder Lister engine (generator) but when you get em goin they sound great
Lamborghini was a tractor manufacturer until the old man got sick of his Ferrari and wanted to make something better. That’s why their logo is a bull rather than something faster.
This is why people think the Earth is flat, they never had to deal with complex machinery...well there's more reasons than that but Instagram doesn't show you how real life works LOL -- this thing is AWESOME and the start up steps are insane, in a good way of course :-)
There's a case to be made that you're correct. Old bombers (B17, B24, B29, etc) had a small, 7hp gasoline engine to provide electrical power for starting their main engines. It was commonly called the "Putt-Putt", even in official documents.
A machine like that, with decent maintenance would last a man a lifetime. And when that man retires he'd still have something with plenty of life left in it to either sell it or pass on to a favorite son or nephew.
I'd always crank the pony on the 8-H on idle and let it warm up and turn the diesel no compression while I drank a cup of coffee. The pony was worn out and would foul a plug if you didn't baby it, which I did anyway as with all the others. When the coffee was gone and the pony warmed up I'd open the pony throttle and kick the compression on. Then after a bit I'd fuel it and see what happened. No pop, more spin, no fuel. Pop? Held the starting lever till it ran. Latches on the pinion were worn out so force was needed. Also found out an oil clutch is like NO clutch till it warms or limbers up. Same as engaged. Like your procedure and the 2!
And i know people today that complain that car manufacturers are still using key start ignition systems instead of the "better" push button start ignitions. Imagine these lazy SOBs having to start one of these bad boys. Love it.
Literally nobody is complaining about no key fobs. I bought a car because it has a key. And something you want to go to the store in five minutes shouldn’t require five minutes to start. That’s why even a Model T was simpler and quicker to start than this.
...réálly enjoyed that, thank you kindly! (getting the oil pressure up makes for longevity...) well done, i really like the caring touch here - this glimpse into times gone by, which i knew well as a young kid, much appreciated.
Love to see how long it takes to start on a cold frosty morning...driver goes to work for 8am..its near 10am before anything gets done...oh look at the time...its break time🤣...what a beauty though...once it gets goin it never stops👍
Step one: evict raccoon from air box. Step two: send a smoke signal to Thomas Edison “ 1: invent electricity “ 2: “ do you know how to rewire a prehistoric catapillar?” 3: have Fred Flintstone make you some oil..
Where I worked in Michigan had a D8 Cat engine with a pony engine from 1950. It had a 6 volt starter as well as the magneto. It had a 2 speed transmission to turn the diesel; low was for turning the diesel with the compression release open to warm the engine and then switch to high to turn the diesel then slowly close the compression release until the diesel fired and caught. Then the pony could be shut down. We could start that thing in any weather. I actually preferred using the crank to start the pony as I could get it to fire quicker than with the starter. The diesel top rpm was 1000 and with 4 gears in the transmission with forward, neutral, reverse; it would do 1.5 mph in 1 st and 12.5 mph in 4 th using No 200 roller chain from the transmission out to the axles. It was fun to run; you picked the gear for the load and let out on the clutch-slowly and then added fuel till the speed you wanted or could get.
Are the cylinder liners specially hardened ? I would have expected that rotating the engine for several minutes (without diesel) would lead to premature cylinder wear.
The oil pump was working while the pony motor pushing the engine. On a slightly side way I'm no metallurgist but I'm pretty sure that back then engine parts werent all that hard because the rings would be brittle. This engine doesnt have a turbo, makes only 40hp, and if I remember doesnt rev over 1000. This engine is huffing and puffing about as hard as grandpa earl watching the price is right. God now I want an old tractor to mess with
jeeeezzzz... i am so glad i did not grow up in that time. i guess i'm spoiled with electronic starter and all that jazz. then again the best sounding engines come from the past. Nothing in this world sounds better than a Detriot Diesel 12v71. well , maybe the Cummins M11 or N14 . i love diesels .
Holly mackerel... going through all that just to start that little diesel engine! All I have to do is turn the key to heat up the glow plugs, turn the fuel level on and start it! With this diesel engine by the time you do all this it's time for lunch !
I was just curious if you live in the Pacific Northwest somewhere because of of your channels name. "Squatch" like as in Sasquatch. I had a Grandfather who had a lot of different heavy equipment and a lot of acres of second generation trees out their. Mostly huge Douglas Firs. But he had one of these Cats and It worked well moving around material and huge trees and stuff. He died back in 2000 and other family members of mine, especially my mother screwed me out of everything. She quickly auctioned off his whole estate and had all those beautiful tress clear-cut. It makes me sick every time I think about it. I just happened to come across this video and it reminded me of working with my Granddad out their around them huge trees and him showing how to start his old D6 just like this.
Back in the day my father had a McCormick Deering WD-9 and it had a gas start too but it was in the same cylinders as the diesel for work/driving if i remember correctly.
So a question.... the fuel control lever appears to look like its graduated... i.e. it has a half way point which doesn't make sense to me.... why do that.... either you fuel a diesel engine or you dont.... so why the graduated fuel control valve ????? the world wants to know this one.... lol :) I am amazed you dont keep the key locked up so no one can steal this american iron.... "the key being the crank" :)
Nice video. I also have a 1937 RD6 that has bee sitting outside for over 20 years. I'm still trying to figure out if its worth saving or, should I just scap it. This helps me a lot... Thank's ,Karl
It's all relative I mean imagine using steam engines and horses to work stuff then this thing comes along it's no different than getting use to using this then one with a key to start it coming along
Good vid, I have a RD6 in the boneyard, basically half a D13000. Used the head off it for a bucyrus equipped with a D13000...5-3/4 bore. Does your pistons have the cutout on top to clear valves? Does the head have the rubber grommets and ferrules for cooling or is it just deck, head gasket and head?

Just like electric cars somewhere down the line is a steam engine, nuclear, hydro, wind solar engine to run the "magic" electric car.
Trust me you would not want to have to Crank that diesel engine to start it
Precisely.

With that complicated startup, at least it shouldn't be stolen.

Fascinating, the amount of ingenuity that took place to get those big engines running. Thanks for posting this piece of American history.
That's a hell of a starting procedure. Diesels have come a long way since then.
This was the beginning of the interest in these machines.
If it had one or 2 more steps to start it , then you could almost say it was a little ridiculous but just the 14 steps this one takes, piece of cake👌🏻
First one I've seen that started like brand new. Looks like you just finished your pony motor rebuild. I like that oil pressure too.
This would work a treat in icy conditions, awesome.
Crazy when you need a engine to start an engine. Serious compression with the size of those pistons and stroke
It was also the state of battery technology back then. They had electric motors moving battleships and aircraft carriers when this thing was made.
The compression you're referring to the engine's compression ratio. Compression ratio is a function of combustion chamber volume, so its shape, not stroke or piston size (which is actually the bore diameter). A 1cc engine could have more "compression" than a 1000cc engine; it's all about geometry.

Awesome.....got same here,WW2 US Army surplus. Runs great.(Holland)
Holy jeepers was waiting for it to blast off in space after that starting procedure
could you add a few more steps to the process? this wasn't complex enough

Starting a modern jet fighter is actually pretty much the same as starting this tractor.

All I have to do is turn the key to heat up the glow plugs, turn the fuel level on and start it!
With this diesel engine by the time you do all this it's time for lunch !
Quite the process!
I was just curious if you live in the Pacific Northwest somewhere because of of your channels name. "Squatch" like as in Sasquatch. I had a Grandfather who had a lot of different heavy equipment and a lot of acres of second generation trees out their. Mostly huge Douglas Firs. But he had one of these Cats and It worked well moving around material and huge trees and stuff.
He died back in 2000 and other family members of mine, especially my mother screwed me out of everything. She quickly auctioned off his whole estate and had all those beautiful tress clear-cut. It makes me sick every time I think about it. I just happened to come across this video and it reminded me of working with my Granddad out their around them huge trees and him showing how to start his old D6 just like this.
Thank you for that i learned a lot
It must take a while to start one of these in the Midwest in the middle of winter.
Back in the day my father had a McCormick Deering WD-9 and it had a gas start too but it was in the same cylinders as the diesel for work/driving if i remember correctly.
Probably a kerosene/distillate tractor. They started on gas, then switched to kerosene when the engine was warm enough.
TD 9 same way main engine had a diesel injectors and carburetor, had another combustion chamber that was valved of to run on Diesel.
Should respray and restore this machine to brand new condition. Would look beautiful with rust removed and a nice paint job
it would yea, if it were a show tractor
Need to pull discs in the field with RD6, a beast
So a question.... the fuel control lever appears to look like its graduated... i.e. it has a half way point which doesn't make sense to me.... why do that.... either you fuel a diesel engine or you dont.... so why the graduated fuel control valve ????? the world wants to know this one.... lol :) I am amazed you dont keep the key locked up so no one can steal this american iron.... "the key being the crank" :)
Nice video. I also have a 1937 RD6 that has bee sitting outside for over 20 years. I'm still trying to figure out if its worth saving or, should I just scap it. This helps me a lot... Thank's ,Karl
Now this is a real man's tractor!
What a sequence. Amazing we survived on this tech - OR - People were way smarter and resourceful back then - ???
It's all relative I mean imagine using steam engines and horses to work stuff then this thing comes along it's no different than getting use to using this then one with a key to start it coming along
i wonder how many people these old Cat tractors maimed, injured, or killed through incorrect starting procedures
"maimed, injured, killed"
Raphael Smithwick yea, they’re three different things
good luck with the eye mate appreciate the videos
If i understand this, that pony motor does the same job as one of those tiny jet engines to power the 747 jet engines?
Good vid, I have a RD6 in the boneyard, basically half a D13000.
Used the head off it for a bucyrus equipped with a D13000...5-3/4 bore.
Does your pistons have the cutout on top to clear valves?
Does the head have the rubber grommets and ferrules for cooling or is it just deck, head gasket and head?
