I've re-built my gearbox with new baulk rings and bearings. When I bolted on the main double roller bearing locking casting it went tight to the casing but the gears would only move about half an inch each way before seeming to come against an obstruction. Loosening the casting off allows the shaft to turn. I've tried the original thin shim with no improvement - is it ok to pack this out further and to what thickness? Also when reverse is selected neither shaft will move - does it look as though I've made a mistake?

It does sound like the bearing needs more shims, have a search on here there will be thread that covers exactly how to do it correctly...or the workshop manual.

 

All looks ok on the photos

 

Reverse wise it needs checking that its moving properly and that the gear is the right way round. You might also find new baulk rings can stick to the cones a bit.

Try it without the layshaft, you may discover it's sticky baulk rings.

Excellent,

Often the 1st gear synchro binds, and needs pulling away by torturing the bearing
