double and triple check your shim job bolt it up and check that the anti reverse is not rubbing on the spur gear just check check and check some more it can be tricky.

i screwed it up, lost the bushing, and the cost of posted for new shims and bushings are crazy, unless someone has some not being used they want rid of, they are an ass to find on retailers web sites.

Re: gearbox/motor help on an m4

errrm really ? arent shims around £3 and bushings like £6 to £15 a set ? maybe thats just me ? are you trying to by gold plated stuff or something ?

I have a set of 8mm bushings somewhere but Im sure you`ll need 6mm or 7mm.
