Gearbox overhaul

I'd been experiencing gear crunching at high rpm shifting for a couple of years, especially in 3rd and 4th gear. After sudden and complete loss of synchronization above 3000 rpm in 5th gear I decided to rebuild the gearbox.
3 main bearings, a complete set of new Synchrotech carbon synchros, new 3/4 sleeve+hub, mint 5/R sleeve, were replaced. 
Very costly rebuild indeed, but the crunching is now completely gone and shifting is much crisper thanks to new carbon synchros.


  1. looks like it really needed that. That was a lot of work! It must feel good having it rebuilt

    1. indeed it feels much better now, not having to worry about gear crunching
