Gazzar Posted November 10, 2023 Author Share Posted November 10, 2023 So, scrap and replace with new, right? But, NLA. So, I had a look at the scrap input gear, and, while the bearing is junk there was only tiny damage on the teeth. Quote Link to comment Share on other sites More sharing options...
Gazzar Posted November 10, 2023 Author Share Posted November 10, 2023 And I've a spare laygear. So, all is well. Quote Link to comment Share on other sites More sharing options...
Gazzar Posted November 10, 2023 Author Share Posted November 10, 2023 Getting the lay gear in place is fairly easy, I found the best way for me, after trying a few things, was to glue the shim and outer bearing set to the casing, drop in the lay gear, then slide in the inner bearing set. Glue, of course, being LM grease. Quote Link to comment Share on other sites More sharing options...
Gazzar Posted November 10, 2023 Author Share Posted November 10, 2023 Next, the input gear. New toy time! Talking the old bearing off the gear from the scrap overdrive was a challenge. The inner rollers were very reluctant to move, and, noteworthy, there wasn't an inner spacer, I wonder did that contribute to the original failure?

Could just be a lost plug was replaced with whatever came to hand. No sign of either, suspect it's just a production refinement. Quote Link to comment Share on other sites More sharing options...
B reg 90 Posted November 11, 2023 Share Posted November 11, 2023 Gazzer, looked at one of those clamshell pullers before and couldn’t quite justify one. what’s your thoughts on them? which one did you buy? apologies for the thread hijack. adrian 1 Quote Link to comment Share on other sites More sharing options...
Gazzar Posted November 11, 2023 Author Share Posted November 11, 2023 It worked well. Needs a decent impact to drive it. I'm glad I had it, no damage to anything. I think it has a very narrow range of applications, as I suspect it only works on a few bearing sizes. I'd be concerned it would be no use for damaged bearings, where the race couldn't take the strain, but, when you need it, you need it. And it wasn't very expensive, I think. Amazon maybe? From the US. As Stephen suggests, make your own. But for me I need to focus. And. On that topic, I'm NOT, going to build up the scrap OD, I've got to get focused. Gavin has some spare bits, so I'll get those ordered today. He likes using the magnet to remove the layshaft. Quote Link to comment Share on other sites More sharing options...

Use a screw driver or any thinner shaft through the cluster and bearings to keep them in a position that you can manipulative them for alignment later - use the smaller shaft or tool to stir the bearings into alignment with the casing bores. Pack the bearing in Vaseline to hold the rollers in place. Quote Link to comment Share on other sites More sharing options...
Gazzar Posted November 12, 2023 Author Share Posted November 12, 2023 Never found the dishwasher any good for the stained casings. But good for the inside. Anyway the ultrasonic has done enough, and a quick gentle wirebrush and wirewool has gone a good enough job. Quote Link to comment Share on other sites More sharing options...

It’s not difficult to get the lay shaft and its bearings into the casing - it’s difficult to get the output shaft and main shaft components in without the lay shaft bearings falling so far out of position that you can’t reinsert the lay shaft itself once all the parts are in. That is why you need to run a thin rod or bar of some sort through the bearings, shims and gear cluster, keeping them in roughly the right place but offset to allow clearance for the other parts to go in, then once the other parts are installed, use the rod to “stir” the lay shaft bearings into the correct position without offset so that the lay shaft will go in. 2 Quote Link to comment Share on other sites More sharing options...

Gazzar Posted January 5 Author Share Posted January 5 Refreshed and somewhat able bodied in the new year. I cleaned up the input gear, and fitted the new bearings. Quote Link to comment Share on other sites More sharing options...
Gazzar Posted January 5 Author Share Posted January 5 I could do with making some soft jaws for the vice.... 1 Quote Link to comment Share on other sites More sharing options...
Gazzar Posted January 5 Author Share Posted January 5 Soft jaws are cheap! Anyway. The synchro unit is okay, compared to a lot. But I was lucky enough to get a bag of new syncro rings for not much money, so these will go on instead of the old ones. Some macro photos!

Gazzar Posted January 5 Author Share Posted January 5 I agree. Anyway. It all went really smoothly after that, and started to look like an overdrive. So I spun it over and..........it baulked at one point in the rotation. A close examination of the new, to me, layshaft showed a cracked tooth. So, I need another new layshaft..... Still, I know how to do a rebuild now. Quote Link to comment Share on other sites More sharing options...
