Gearbox:
All bushings and bearings new. Layshaft was reground and all bushings fitted nicely. Even got one of those fancy SRM nut with the seal.
I had to use three gear boxes to get enough parts for 1 and a half.
Both shafts have a pressed on gear, these each have a circle as a gear stop.
In taking each box apart, I noticed that none of the gears were pressed home on the clips. They varied from maybe 10 thousand to maybe 40 thousandths. The endfloat on the two boxes that were not rusted tight was good. The third box was immobile and a complete mess.
I just pressed the gear onto the layshaft and pressed it home. My endfloat is excessive, maybe 25 thousandths.
It took a lot of pressure to press that home, meaning it is not going to wiggle, vibrate, or ever come back off without a press.
I started wondering, because none of the six shafts had the gear pressed completely home if this is how BSA controlled endfloat when these were built at the factory?
It would be a fast, economical way to do this in my thinking...
