I'm in the precess of reassembling my gearbox and have hit a problem.
This is the bit I'm talking about:
This shot does not show the problem because of the perspective, but demonstrates quite nicely how much water/condensation there must have been in the box at some time!
The gearshift pawl is not making contact with its spring and so will not move to engage with the ratchet:
The pawl is new, purchased from RGM and I suspect, like some of the other stuff I have bought from them, is not quite to spec. I have not had the chance to compare it with another pawl - I chucked the old one and can't get to Norvil (just up the road from here) until next week to do a comparison.
I seem to have two options. Either grind out the spring indentations in the gearshift stop plate to bring the spring closer to the pawl, or to wait until I can replace the pawl. Of course, because the bike was a real 'bitsa', the stop plate could be wrong. I'd have thought this unlikely, given the age of the design of the box. I do know that original pawl and spring were in proper contact. However its a 31**** box, but contained some gears from pre Commando days!!!
I would be happy to grind out the stop plate indentations, but do not know how critical the spring pressure or equal spring pressure is to correct operation. Also, can anyone help me out with a measurement across the widest part of the pawl so that I can compare it with mine?
Cheers, Bob
