I have an MB with a CJ2A engine in it. It used to start great, then the
starter got weak. I had it totally revamped and took the jeep 250 miles
away to my dads farm. Since then the bendix rarely engages, and I have to
shake it while someone else holds the starter switch down just to get it to
engage. After doing that for two years, the flywheel ring gear is all
butchered up. There is no good place to work on it at the farm, and no
competent mechanics nearby.

This week I took off the starter, counted the teeth. There are nine (9). I
did not count the teeth on the flywheel.
The old bendix drive which I had replaced on the starter has ten (10) teeth
(Yes, I kept the old parts, just in case...).

I have a Bendix Drive, NOT the Overrunning Clutch Drive or the Folo-Thru
Drive models shown in my CJ2A manual.

My manuals have different info on starters, ie.

Universal Jeep Service Manual
Bendix Folo-thru, 9 teeth, mates to flywheel with 129 teeth, .375" tooth
face width.

Universal Jeep Parts Lists, Group 10-21,
for CJ2A Flywheel #A-1443 and ring gear #635394 with 97 teeth.
for CJ3A Flywheel #641960 and ring gear #641955 with ?? teeth.

Should I :
Buy a new ring gear, heat it up and install it in the field? Is that hard
to do?
Buy a new flywheel, install it in the field? Is this a bad idea due to
balancing problems?
Go back down to the farm and put the 10 teeth bendix back on the starter?
Roll start the jeep from now on?

Your help is appreciated!

Brent
