Made by our good selves to replace the worn bush in your BSA standard 4 speed Mainshaft top gear (Sleeve Gear)

41-3045 57-2753

Machined as a full bronze bush to help with heat dissipation.

These two bushes replace the single long bush used on earlier engines.

Two are required but sold individually.

Bushes once press in need finishing to size.

It's always better to hone to size, rather than ream if possible.

If you are unable to do this we have a comprehensive machine shop that you can send your sleeve gear too.

A fitting and finishing charge will be required.

Our sleeve gears do not require them as we have modified the sleeve gear
