[QUOTE="john998, post: 1090, member: 289"] [b]Clutch[/b] Hello Allan, The end float is set by a spacer E76 in the gearbox between the constant mesh pinion G6 and the input bearing. It is not critical, as the nut on the output sprocket holds the hollow shaft over to one side and the clutch nut holds G6 over to the other. As long as there is movement before those nuts are in place, to allow oil into the bushes of the hollow shaft. A tenth of an inch should be OK, the only caveat is that if the constant mesh pinion is too far over to the clutch side, this will effect the depth of engagement of top gear. As far as looking inside the box goes, the lay shaft will almost certainly fall out and you will be stuck with a tricky job. The only thing you have to remove on the gear change side is the kick start mechanism, held by one cir-clip. It is possible to assemble the gearbox without removing the cam plate spindle. Wire all the bolts and the selector paul hex on the gear box end plate. On an different note I shall be missing for a while as I am going to the Hever Rally. Regards John. [/QUOTE]
