Does anyone have a kick start bush retaining strap for a 3 speed gearbox (1947) surplus to requirements. The kick start bush has rotated on mine and the slot for the ratchet to engage in is at the bottom part of the rotation. The part that retains this bush is missing on the strap that I have?
Earlier gearboxes have the kickstart boss held in position by a small dowel that engages into the gearbox end cover, but numpties abuse this by operating the kickstart with the bike on the rear stand, so the pedal goes to the limit and tries to turn the boss, which causes the dowel to tear itself a slot in the end cover. This can be alloy welded, but the best long-term remedy is to go for the later type pedal stop, held in place by two of the end-cover retaining sleeve nuts, and by the central 3/8″ dowel. The stop has a tongue on its bottom edge which engages with a cut-out in the flange of the kickstart boss, and stops it from turning. I believe that Eddie Shermer and Alan Noakes can supply them.
Remove the kick start pawl, remove all the bolts.
The cover should move a bit, I then heat up the end cover with a gas torch to make it expand and a sharp, quick pull, the bearing should be free from the end case
