Gear selection issue, when I tighten mainshaft nut, loose ability to select lower gears (2nd, neutral and 1st) and same with outer cover off and manually moving quadrant. Gearbox has all new internals, bushes, gears, kickstart, sleeve gear (AN) , bearings etc, except selector forks, main and layshaft which have checked for strainghtness. Roller bearing on lay, layshaft endfloat 0.006. after shimming. Gears, bushes slide on shafts, only 1st main bit tight on spline but does not extend past boss. Have pulled apart a few times and all appears OK and quadrant timed, selecting all camplate tracks/gear positions with inner cover on, gears out and in. Any ideas? it must be related to the mainshaft but would expect that when tightening mainshaft nut would only pull shaft away from within sleeve gear a small amount and it still rotates OK with no stiff spots.
