When I got my engine back from a local overhaul, I added my rebuild T-90 with new clutch and ring gear on fly wheel (old one had a bad spot chewed into the teeth), dropped it on the chassis and did a fire-up check. (normal fussing with the timing and fuel, but that worked ok) But I threw significant (1" x 1/4" x 1/4") chunk out of the flywheel! OK, new flywheel comes with ring gear and I get it all back together on the chassis (but do not try to start again at that time). Then while I was doing the sheet metal stuff on the body, I sent the starter and generator to a local auto-electric shop for new brushes, and clean up. The body work went a lot longer than I expected. Soooo... two years later I get it all put back together and (with new wiring) turn the switch to start, and the starter spins like crazy. No evidence that it will engage the flywheel. Now the Jeep is at the auto-electric shop and they claim that my flywheel ring gear is "the wrong one." I have 3 ring gears now... the original, the one on the chipped flywheel, and the one in the Jeep. The Jeep is still at the shop, but the two that I can put my hands on are exactly the same, 129 teeth. Would a replacement F134 flywheel come with a different ring gear?
