BSA Thrust plate — clutch lift mechanism

A thrust plate from the clutch lift mechanism, located in the outer timing cover, kickstart, and footchange area.

PN · 57-4497

This is a thrust plate out of the timing cover area, tied to the clutch lift mechanism. The catalog places it in the outer timing cover, kickstart, and footchange figure, so it lives on that side of the engine where the kickstart and gearchange mechanisms are housed.

We only see this part turning up in one catalog listing, and the year range on file is a single model season, so we don't have a lot of extra detail to pass along beyond what the parts book says. A thrust plate in this kind of assembly generally sits against a moving component to take up end-float or provide a bearing surface, keeping things from rubbing metal-on-metal where they shouldn't.

If you're chasing this part down, give us a call and we'll confirm it matches what's on your bike before you order — the record here is thin enough that we'd rather check than guess.
