Yeah, I new that. I did not try to force the bolts, just threaded them in till I fixed the problem and put the tiller mount back on.

I got the oil drained and the cover taken off. I got bad news. I found a lot of um stuff in the bottom. I found a gear tooth, a bearing ball, and their weight in metal shards. the crown is in horrid shape, cut my finger on every tooth. the whole system has a little bit of play. I cannot find the gear with the missing tooth. the spiders, and the crown are not missing it, but I don't want to stick my finger in to check the pinion while it is moving. the gasket was in decent shape. it was dry except for the bottom portion, which was wet everwhere. how do I get a new gasket to not be so attracted to the housing? I'm using a paint scraper, and it is takeing a long time, like an hour.

Unfortunate news Tyler. In my experience there are very few "easy" ways to get a gasket off once they have been there a few years. If you are using a paint scraper, be sure to go easy with the presure and try not to notch the gasket surface. It will make your new gasket a lot happier when you have a flat clean surface to stick to. Use some brake cleaner or alcohol on a rag to make sure the gasket surface is perfectly clean before you install the new one.

Thanks for the advice. I did not know if I could use brakclean, because it would get inside, and internal parts would not be happy. I am going in to town to get a roll of gasket material. how thick? any other suggestions? can I still use ground engaging implements/plulling with the missing tooth and ball?

I always use an angle grinder with a wire brush on it. It'll clean it right up!

If you've got a ball bearing and gear tooth floating around in there, I would tear the rear apart and see what's going on. Something had to cause the tooth to break off and a bearing to fail. You should be able to find good used gears easily.

I always spray cleaners on a rag, then apply it to the surface being cleaned. It cuts down on over-spray, especially when around freshly painting items! Going to have to take a pass on the gasket making material, it's been 20 years since I have actually made one from scratch.

Sorry to say. I don't have the time or the desire to tear into the rear end. I think I might just pick up the 128 with a creeper, and if and when the rear goes on the 1200, the other rear will just slide right in. I have not seen any other gear drives around except for the 128, (400 miles from me) and another gear drive (about 60 miles away) those are the only two I know of. If I had a little bit more experience and time, I might do it. but not this time.

I know it's not as pretty but I use this blue sealant. One tube will last several times.

Ok. I finnaly go the entinre gasket removed from the rear end.I used industrial strength CNH penetrating oil to soften it up. I determined that the loose tooth must be off a transmission gear, since the spiders, and the crown and pinion all had them. the tooth is very rounded on the front, makin me think that was wear from being shifted in and out of gear. a real harsh shift might have caused it to break. I used some 180 dry sandpaper to buff up the gasket contact surface. the rear cover is rust pitted bad on the outside. the tiller mount was left on and water sat in there for a while. not affecting its function though. I used a oil magnet to retrive any metal shavings from inside the housing. should be ready for the hy-tran as soon as I gest some gasket stuff
