I'm about to put a new ring gear onto exsisting flywheel. Old ring gear came off very hard but OK. Noticed on diameter of flywheel where ring gear was seated that it's a different diameter than further away from this area. There are definately two diameters and the one further away from the flywheel shoulder is larger. This means that in cooling flywheel down and heating ring gear I must hope for enough growth/schrinkage to be able to slip/tap ring gear over a larger diameter than the diameter it actually seats on. I looked at old ring gear inside diameter and both outside diameters on flywheel and saw NO EVIDENCE of the ring gear spinning and causing the difference in diameter. No pickup or scoring of any kind. With a steel ring gear and a cast flywheel there should have been something noticable if ring gear had spun. It almost looks like it's been manufactured that way. Has anyone out there seen this slight difference in the diameter where the ring gear goes onto the flywheel, (looks like maybe .010" on a dia. larger at first then smaller against the shoulder)? Would be nice to know that new ring gear will fit OK onto this flywheel. Have no way of accurately measuring these diameters.

The garden was already sprouting when we hooked up the mid-mount shovel cultivators to the Pony. The seed bed was soft enough that the rear end would spin and slowly work its way to the downhill side of the gardens slight incline. From this, we learned our lesson sinc
