So has to run rich after Pony motor is fully warmed up.

Anyone know where can I buy brakes (shoes, cylinders, shoe springs) for this model 8T7290, 1955, driveline brake also?

What is the lever right above the button for the electric push start

Do not give it Ether! Also let the Diesel Build oil pressure before giving it Fuel and Compression. Than Close The decompression and and let the engine Warm up Before giving it fuel.

Hello sir, I have recently acquired the same model of machine it runs and your pony motor start video was very helpful thank u , do u have a operating instruction guide video possibly or know of one that u would recommend? Thank you

Thank you for explaining everything. That is seriously lacking on the 'Tube.

i was taught to let it turn over till oil pressure comes up then start . who knows

Parabéns pelo vídeo amigo, sonho ter uma motoniveladora caterpillar mecânica, mas, no país que moro, é muito difícil de comprar maquinário. Forte abraço amigo

How long does the pony motor need to run to get everything warmed up?

You didn't mention a compression release on the diesel. I assume you have one and did use it since you seemed to be handling two levers when you engaged the pony motor to the diesel. Your diesel starts right up, but it seems that most people let the diesel turn a while with the compression release employed to warm the diesel and make it start gently. Great video.

Using a starter motor is cheating you should use the hand crank, it will give you manly arms

I used to stop and start an old a-jax one lunger oil pump jack. We used gas,then propane then to natural gas. It was wild spinning that big wheel.

Great video Darren! That looks like it will work for many more years.

Great detail on how to. Thanks.

Great video thanks for posting

I use a dryer exaust tube put oner pony and plow exaust on fuil rail in real cold if i must start big engin works realy well

Great motor grader ... what a wonderful engineering 👏

Aack! It is NOT a 'pony' motor. Caterpillar NEVER called it that. The correct term is 'starting engine'. Please stop using that other word. It hurts the ears.

Nice video . Only one thing scares me . Seriously be absolutely certain the transmission is in neutral . You are knocking on deaths door where you are standing .

I used to start a Cat D69U the same way, one question though, you dont open the compression release? I would have to release the compression release then as the Diesel engine would start puffing out smoke, I would engage the compression release.

I would build fuel& oil presure then hit compresion releaf

Long live the D318

I got the same name just spelled Darrin. Also have the same engine but in a D6

Thank you for the wonderful clear video! What a nice old grader you have with the pony start! Where did you film the grader start? It looks to be the foothills somewhere out west.

I thought it was hard to do it's that easy

Gawd, that brings back wonderful memories. Thank you mate.😊👍

Is that pony a 2 stroke?

Not being rude I got a 1950 cat d4 6u dozer in the winter just let the pony motor run the Diesel engine with compression closed for 20 30mins depending how cold then open the fuel and she will start right up with out any either but starting up the pony slowly close the compression but very nice grader tho

What a process. We’re so spoiled now am days.

nice

Man am I glad I found this I've been hill starting mine !

2:25 "...and then preset my diesel fuel for startup..." Not to be rude, but isn't it a better practice to start the pony motor with the main engine set to compression release and starved for fuel. Then, once the main engine has oil pressure and has warmed up a bit, to shut off the compression release, then to introduce diesel fuel?

If you ever need ether in the diesel you are doing something wrong. Daddy had an RD-8 and the starting sequence goes like this. Start the pony, ours was a crank handle. Let it warm up, 3-4 up to 10-15 minutes depending on temp. Very cold weather, half a tank of gas. Doing this you are warming the coolant shared by both engines. Next put pony in low, it was a two speed some were single, and start the main turning over. This is pulling warm air from the pony exhaust that is heating the intake manifold internally into the main cylinders. After a few minutes, again time varies by temp, put the pony in high and throw compression lever to half. Now watch for the temp gauge to start to move. Once you get a little temp in the water jacket, throw compression to full and put the fuel to it. If it doesn't start after 2 revolutions, shut the fuel off and let it warm up some more. If you try any and start it before it's ready, you're just dumping raw fuel into the cylinders washing the lube oil off the cylinder walls and causing extreme wear and diluting the lube oil. NEVER use ether. Starting at 20 below takes a couple tanks of gas but no ether. Hope this helps. Please feel free to ask me questions. I loved that old Cat with it's LeTourneau pan.

It's not a pony doorknob. It's a pup.

What is the lever above the ignition and starter button? Compression release?

Does the starter engine run the exhaust through the big engine and warm it? Thanks for the video.

great video. keep up the good work and have fun with your CAT.
