Hello, I have a 5mt duel range transmission in my brat, I would like to have it rebuilt (noisy bearings) it's annoyingly whiney, are there parts avaliable to rebuild them, bearings, sycros, I'm shure someone has been through this, thanks.

Yes, some of the parts are still available. I personally wouldn't rebuild the whole thing if just the bearings are noisy. The sychros rarely, if ever, go bad. To clarify, if it's grinding going into a gear, it's not the synchro. It's the blocking ring that's worn. It's a common misconception since the blocking ring is part of the synchro assembly, but serviced separately. It's a cone shaped bronze ring that rides on the cone shaped side of the synchro hub. When you shift, the shift ring that is moved by the shift fork slides over the outside of it pushing it against the synchro hub causing it to slow down  so the speed between the two gears/shafts matches and they mesh without grinding.I would replace just the blocking ring for the gear that's grinding.

Sycros are fine I only threw the question in because I was asking about part availability, Thanks.

Does anyone have some suggestions on where to get the parts?
