Thank you so much for going deeper into the old gear box! I’d made a new bush for that area too. We had some aluminum nickel bronze bar ends so that’s what I used. I’m curious why you used stainless instead of bronze🤔. When I installed the new seal it made it turn alot slower. I’’m hoping it wears in eventually. My complete gear assemblys needed some better less-worn gears which I found on ebay. Just hoping that I got the spacers correct in them. It’s great watching you do all these projects!
Hunter, Thanks for your comment, always appreciated. I guess you have noticed that I am not a precision engineer or bearing expert but over the years I have pressed out many steel bushes from gearboxes. I sometimes buy ready-made bearings but there’s no fun in that. Where “spinning” shafts are concerned I would always use Phos_Bronze or iolite type bushes but on kickstart and gear lever shafts which don’t spin I have no problem with stainless as there is less chance of corrosion. I’ve checked the subject on Google and it seems stainless is OK. If any experts out there can advise me further it would be appreciated, sharing knowledge is what RU-vid is all about Cheers B
Hi Brian. thanks for the vids - i'm refurbishing a similar box. I noticed you didn't check or shim the end float on the selector shaft or layshaft so the gears mesh well and the dogs are centered. I'm assuming i need to do this... no? yes? thanks
Hi, thanks for the comment. This was the first gearbox I had apart and didn’t find any shims inside, I more or less rebuilt it as found. I am about to refurb another SA box and will measure the end float and look for shims. The video should be on RU-vid shortly. Thanks again Brian
Nice work Brian! Do you feel the gearbox bearing will last longer running in oil as opposed to leaving the shielding on and letting it run in it's own grease?
Dave, another good question.The BSA bearings I pressed out were Hoffman un- shielded That’s why I removed the shielding, I guess the White Grease in the bearing will dissolve in the oil in the gearbox over time. I bought a second gearbox for spares and noticed that it was full of White Grease when I took the covers off and I would worry that the grease would not reach all the moving parts in the box. I’ve noticed some guys on the BSA forums do prefer grease but I guess it’s to reduce the chance of oil leaks. Thanks again, great comment. Cheers B
