Cat d6 9u starter and wiring

Anyone happen to have a wiring diagram for this starter and anyone know what starter this is? It came out of a Cat d6 9u

The battery cable going to the big stud on the end of the starter is your ground, most likely Negative. The battery cable going to the solenoid is positive. There should be two wires running to a starter switch up on the operators platform. One will run back to that positive battery cable and the other will run to a small stud or flat terminal connection on that 1980- 1990’s era ford F series etc firewall solenoid.

My question: I see a pinion and clutch lever for a pony, does the pony still function? I have several machines set up as "dual start", DE or pony whatever the mood strikes. JM

Thank you, I kind of figured that, I tried to jump the starter directly but the starter didn't make a sound. I figured it would have made a noise with 12 volt batteries but nothing. Looks like it is coming out

This dozer has a pony and electric start. Someone robbed the mag off it way before I got this dozer. A mouse made a home in it and I cleaned it out the best I could. I’m afraid if I turn it over, more mouse house could clog something up down there unless it doesn’t matter then I would be happy to use the pony. The previous owner rolled started the dozer.

That starter is the original style bendex or inertia drive starter. That is what these tractors used from the 1950’s when it was a factory option until the mid 90’s when the conversion drive and nose cone became available. That starter should be 24 volt unless someone went through and changed the internals.

I got the starter out and it spins but backwards for whatever reason and keeps the bendix retracted. We took the back cover off and it’s all oil soaked

clean the brushes up.

clean every thing. the bendix could be stuck make sure it moves freely by hand if it does but wont with power applied then its wired back wards or the brushes are in the wrong order.
