D2 electric starter conversion for main engine

Thanks TOGNOT for the reply. I did search and I found a post going back to August of 2012 by KCB. In that post there are two pictures. The first picture is the same as the housing on my tractor. The next picture is an example of what I want to achieve. In the photo is a plate with 3 bolts. I want to machine out the hole and 3 bolt holes to be as accurate as possible. Having to look for a genset housing will be next to impossible in my part of the world! Wondering if there is a drawing available of this with the specifications. I would like to keep the pony for those minus temperature days, and to have an electric starter for the warm days.

Hi, I now have the information for machining the starter hole and bolt pattern. I have in my parts storage several Delco Starters, both 40Mt and 42Mt. Can someone advise as where I can purchase the proper Bendix and the part number. Also will the Bendix work with the same starter heads ?

J&R 220-12197R 220-12358 Bendix. Or just buy gear replace 42MT straight tooth gear..

Call Kenny at CC Battery in Corpus Cristi. 800 531-1038. I just got a new bendix for my D9G when Cat couldn't find one.
