I bought this box off a French guy at Kempton about 5 years ago for £100. It had two layers of army green paint heavily glooped over a layer of black paint, which I've stripped off.
It clicked nicely through all gears in the vice and since taking it apart, the gears all look like new. The mainshaft is an even .001" down from 7/8" through the sleeve gear and there is a little bit of slop! So when Les opens up for business again on the 30th? I'll order a new sleeve gear bush/bushes and ream it to size. Les has the original gaskets too, not the thick ones that are on sale elsewhere. I've also got a sealed FAG bearing coming from Darren W.
The pivot pin for the clutch lever was a bit worn, so I cut a new one from a piece of 1/4" silver steel.
It's just a spare gearbox in case either of mine go wrong......Hopefully I'll never need it:relaxed: Ron
It must be the Corona 'catchup' virus...I've just rebuilt a BSA box for a late A10 RGS that I 'found' when I was looking for something else in the workshop loft...I can't even remember buying it so it's been there a while!....Ian
My mate John made me a new bronze sleeve gear bush. The one I pressed out was brass? I heated the case and fitted Darren's sealed bearing, fitted two new gear change springs and proceeded with assembly this far. It clicks through the gears.... As well as an M20 box can in a vice!!
Tool can be used with rubber stop in place, First roughly place quadrant into outer case & hook the spring onto quadrant, then insert tool and turn until it hits the stop(2nd photo) then turn tool clockwise until you clear the stop rubber in outer case then just push quadrant into outer case. 1st photo shows how to use tool to remove quadrant, same thing insert tool till it catches the return spring the turn clockwise and wiggle out quadrant once clear of stop on outer casing.I made this tool as I got fed up with fiddling around trying to get return spring into place this tool makes it so easy and is worth the 1/2 hour of time to make....
