BMC Engine gearbox JCB 3C 1974

Post by Andy JCB » Sat May 23, 2020 9:45 pm

After fitting a new selector rail into my JCB 3C 1974 I can still not get the gearbox cover to fit with the gears selecting, I must have disturbed the gear selection system. I can get the cover down but the gear stick is locked, Any help would be welcomed as I need the digger for mucking out buildings.

Thank You Andy

You have probably missed the selector fotks on some of the gears. It takes a bit of fiddling and some luck to get them all in the correct spot the first time.
