[QUOTE="John Appleton, post: 7994, member: 760"] The main shaft selector fork is totally b..g...d and has filled its corresponding channel between the dogs with brass. Hi Upstreeter, my Rapide used to do this on a regular basis! Found the cause to be excess end float in the clutch mainshaft, which I rectified by fitting a 40 thou. spacer ,in addition to E76, behind the bearing in the gearbox manhole cover. You should also check that the G30 spindle is not bent as a result of the siezure.It is also worth mentioning that ,since renewing the gearbox bearings in a recent rebuild, the extra spacer is no longer necessary although there is no obvious wear in the original bearings John [/QUOTE]
