is the engagement lever always been cut like that?? do the drive dogs spin when you spin the pulley with the lever pulled forward?
(the inside of the wheels may be stripped), i haven't pulled a gearbox apart , never had to, but i have a spare, just have to make sure it's ok.
also, the belt in the top pick is not on right, check the wear on the post...
