Uh-oh! - I can see OM snorting fire from his nostrils over this website! They claim that drilling holes for MT series starters in the flywheel housing is prone to major error .. and that conversions using the pony helical gear is the only way to go! 😞
They are pretty shy on a lot of further detailed info .. and pricing in particular. They look like an expensive conversion.

We had a post on that topic just a couple of days ago.

Those conversions are a genuine POS.....I don't think their alternator conversions are any better.
I didn't find it all that hard. .except for boring the 3 5/8" hole, and that was just tedious as I used a 1/2" drill motor and had to stop frequently to let it cool. The first time I did this conversion I used a bi-metal hole saw and had to resharpen it several times. .this time I used a hole saw that was carbide tipped. The trick is to measure everything, then recheck the measurements and just before you start, check 'em again leaving several days between each check. I tapped the holes 1/2-13 NC and got bushings from NAPA to sleeve the holes in the drive end housing from the 5/8" holes that was in it.
All in all, I'm quite satisfied with the end job. Now if I could just find another adapter that bolts in where the generator is so I could mount an alternator. Either that or sacrifice one of the generators I have and make my own adapter.
