Right but this thing is way, way beyond taking care of that.

Got a new rear bearing and got back on the transmission a little yesterday. After polishing the shaft mating area I had about .002 interference fit with the new bearing. I honed the inner part of the bearing down until it was around .001 interference, set my heat gun on the inner race awhile until it got up to 200 F and then started it on. Still pretty snug but an least when I tapped on it with a brash punch and small hammer it was now moving so after what seemed like about 60 to 70 punch strikes all around the inner hub it was on. The rest of it went pretty easily. The sticky green transmission assembly lube really holds those rollers in place so no issues after all this time with the countershaft.

I did note that if I screwed the 1-2 screw that holds the detent and spring down tight under the top plate - it was locking the fork/shaft up from sliding. So I had to back it off about 1 to 1-1/2 turns before it shifted freely. The 3-4 and reverse all seemed fine. Good idea to check that everything shifts good and spins fine before buttoning up.

Just have the gasketed parts to assemble and it should be ready to go.

Finished up the reassembly today. Took extra pains to seal all gaskets/bolts. Applied a bead of sealant on all surfaces, installed dry bolts and lightly snugged parts to squeeze and spread sealant but not tighten fully. Then pulled bolts out one by one and coated them with gray RTV and reinstalled and then torqued tight. I sealed the vent holes in the lid gasket with RTV to keep the top of the gasket dry. Hopefully no leaks this time.



Below is a good set of instructions that I was given a link to. It's a little tedious to use because of all the separate photo links and some of the links to photos connect to incorrect photos. But it has some excellent illustrations of the main cluster assemblies and other sub-assemblies that are hard to find elsewhere. I printed out the main narrative and 3 or 4 of the sub-assembly pictures for good detail.

Noticed one issue with my throw out bearing that I need to look into before reinstalling but I think I'll post it in the Transmission forum.

Congratulations Dan, looks great! I recall that Dan Williams instructed me to put some cheap 80-90 weight oil in my new top loader and then take it for a couple of slow laps around the track making sure to not exceed 4,000 rpms and then drain the oil and fill with a high quality 80-90. The idea was to flush out the packing grease and remove any metal pieces as the new gears mesh.

Hope everything goes well. Saw your other posting and do not have anything to suggest regarding the spring.

Thanks, I will probably do something along those lines. It's pretty easy to drain and fill the Toploader due to the drain plug. Interestingly, I still found assembly lube traces inside the cluster gear roller area and in the input roller bearing area. That stuff hangs on.

Well, from the outside it looks perfect....

It looks even better now.





I'm going to say the TO Bearing is self aligning. The inner race has about 1/16 inch, maybe a bit more, lateral play which seems to make no difference in spinning effort or smoothness.

When I pulled out the TO Bearing and I quickly discovered that it would not be a good idea to get carried away with a grease gun lubing these things. When I pulled it out it was well coated/gunked up with grease that had worked it's way out of the race. Fortunately it seems to be a pretty stiff, high temp grease so although it go flung around inside the bellhousing a little, it just stuck and didn't run anywhere. Wiped it down, gave it a very, very light shot of fresh grease and put it back in. Adjusted the clutch where I can push on the fork to bottom the slave and get a slight bit of play at the TO Bearing.

Unfortunately too hot to finish putting the interior back in today.

Well that looks brand spanking new now.

Dan,
Seeing your toploader I'm thinking it's a waste to cover it up with a tunnel! It's a thing of beauty. Plus think how fast you'll feel you're going when you can see the road moving under your feet, and the rocks hitting you in the leg!
