I have the gearbox apart, so far so good.
the front cover is leaky and the first motion shaft has lots of runout. New bearing

There's 8 thou endfloat in the laygear thrust washers, I need to see if that's acceptable
The layshaft seems fine and not too worn
what has surprised me is the reverse idler and shaft which is very....very worn

that has lead to very worn teeth on the idler
