Re: Gearbox Noise
2 questions: Has the nut on the kickstart end of the mainshaft got a large internal chamfer on the side which should abut the kickstart ratchet? No. There's a small chamfer, sufficient to clear the bottom of the thread on the shaft. I'll turn a shallow depression there, 0.5 mm deep, to reduce the e...

Re: Gearbox Noise
Here's the mainshaft end float Mick, you can see the gap under the nut.
Light bulb moment - the mainshaft doesn't pull up against the bearing, because the end float is needed to allow mainshaft third to spin.

Re: Gearbox Noise
Not sure how to rationalise near zero axial on the mainshaft small bearing and 0.040" end float on the shaft, was the clamping to the bearing inner removed when measured? No - I hadn't dismantled anything bar the clutch at that point. I'll put the mainshaft back in without the rest of the clus...

Re: Gearbox Noise

They've only done 5000 miles. Fifteen minutes work with various micrometers revealed this: Layshaft 2nd bush ...

Re: Gearbox Noise
Not yet Mick - basically I only had time to pull it out and get it clean. The forks look good and they are a good fit in their grooves; they move easily on the drum but I haven't had the pins out yet.

Re: Gearbox Noise
The latest news is that the BA gearbox from my Square Four is now stripped and washed out. If you recall, some dogs were clattering at idle, in neutral. For the record, there's 0.88 mm (35 thou or just over 1/32") end float on the main shaft and about 0.23 mm (9 thou) on the layshaft and select...

Re: 1930 LF
I've been using this stuff on headlamp switches. Strips the tarnish off brass in few minutes:

Works great on watch movements too, in case your speedo needs a clean!
