Question for brain trust----talking to OM

I haven't tried using a 30MT but from what I can tell the same parts used to convert a 40, 42, 50MT starter with SAE #3 mounting pattern would also work on a 30MT but the motor itself is of lesser hp.

Do you have a reference for the starters? I mean the source for the dimensional measurements, I can't read the numbers in your pages on the site. I want to be sure
that the bendix is correct to match to the ring gear. Was there a model, circa 50's, that came with direct start and generator? If so I'd like to see a picture, to fabricate a bracket for the generator. On this genset there is a winterized package that features a diesel fired coolant warmer (electric element) and by size could fit the space left by pony removal, ever heard of something like that on a cat?

What dimensions are you looking for?
Yes, Cat had direct electric start in about 1955. It was an inertia type drive unit with separate solenoid and glow plug provisions. Requires the larger later type pre-combustion chambers. Either an 11 tooth or 12 tooth helical drive is required (11 tooth preferred). Generator was direct mount gear drive.
All manner of preheat devices, gas fired, diesel fired, and electric have been utilized.
