Hi all. I'm working on a gearbox for my WM21 build. This is a first for me, but OK so far... Gears, forks, etc appear to be in good shape visually. I'm replacing both bearings, using a sealed drive side and have read many of the helpful threads and technical articles on this site. However my manuals don't give tolerances for the bushes, especially the sleeve gear. Does anyone have these to hand?
