BSA Unit A50 A65 - Gearbox & Clutch


Specialist rebuilds on both the standard and close ratio versions The gearboxes are stripped, assessed and an estimate is produced for the work and parts required for the rebuild. Worn gears are replaced along with the sleeve gear bushes and the kick-start ratchet gear bush on the main shaft.  New sprockets, tab washers and modern oil seals are used throughout the rebuild. 


Modern friction material in the clutch plates and to fitting the SRM clutch pressure plate conversion (available on web shop) will improve the engagement and release of the clutch. The primary transmission on the engine can be fitted with a complete modern style alloy clutch combined with a belt drive.
