I have recently had my bus restored, apart from paint. The engine/box was out and the engine rebuilt. Gearbox wasn't but is/was fine. I have driven the bus 130 miles and the gears were hit and miss. 3 times I broke down. I adjusted the gears by loosening the 2 bolts at the bottom of the gear stick procedure and it is perfect when the engine is off. BUT when I start the engine I cant select any gears 9 out of 10 times I try, also when going for reverse it crunches real bad. Not sure what has happened, it was OK before the engine was taken out. Any ideas people. Thanks guys
Well, I have seen clutches bind up on the friction surfaces if they're left somewhere damp, but as snotty says, you ideally want the bite nearer the top
