These track vehicles are better than women!

Looks great!! Could you explain what happened? Looks like you started a little engine to get the main goin??

[BWAGG1990]

we got a motor just like that (not that pretty tho lol) for our saw mill, it was originally out of a d7, then used as a generator (with only 750 hrs!), we had the pony motor but the arm would sometimes kick back and itd like to tear your arm off, so we got a starter for it but had to switch to 24v and it does awesome now, we love it, burns about 1 1/2 gallon an hour at near full throttle, and it wont ever even think about bogging down, governor hasnt kicked in once, gotta love these old motors!!

Sounds like that big diesel is running at about 300 RPM!!

falou em caterpillar....não tenho palavras..ela fala por nós mecanico e operadaor é a maquina.

THAT started way to easy....somebody knew what they were doing when they rebuilt that diesel engine. IMO

The starter motor, pony/donkey, tomato/tomahto, is a 2 cylinder 4 cycle made by Cat. It shares coolant with the main diesel motor and the exhaust goes to a jacket around the intake manifold. The main motor has a start/run lever. When in the start position the exhaust valves are held off their seats to relieve compression for getting the pony engaged and the main spinning. Once it's spinning it's switched to run and compression starts heating the cylinders. Fuel lever turns fuel on. It starts.

@24preacherboy Thats what I have been saying all along...its a pony engine. Novachevyguy was saying it was start on gas and switch over to diesel

[mowrman100]

fucking NICE! That's sexier than Jennifer Anniston!

@wlaukaitis thats a pony engine. the compression on diesel engines like these are too high for a electric motor it wont even turn it over

[GDLutz]

@wlaukaitis that is exactly what he was doing. Before the technology for electric start with batteries, engines were started by hand crank, but these giant engines were much too big to be started by hand. the solution was to have a small engine that you started by hand and then used to start the larger engine. So the little engine performs the same function as the electric starter motor in your car.

@wlaukaitis Pony motor, little 2 stroke gas starter engine for the big diesel. Back then electric starters weren't very efficient, and you would need a gigantic electric starter and like 5 batteries to handle the compression of the diesels. Thus the high rpm (3500-4000?) 2 cycle pony motor.
