BSA Clutch spring
A clutch pressure-plate spring for the primary chaincase clutch assembly, cataloged 1969-1972.
68-3321 is a clutch spring that sits in the primary chaincase, working against the clutch pressure plate to keep the clutch plates clamped together. It shows up across catalog listings from 1969 through 1972 under the clutch and primary cover figures, so it belongs to that era's clutch assembly.

These springs work in a set around the pressure plate, and over time they can lose tension, which shows up as clutch slip or a clutch that doesn't fully disengage. If you're rebuilding a clutch or chasing a slipping problem, it's worth checking all of them together rather than swapping just one.
Our catalog record doesn't tie this to a specific model, so give us a call or check your parts book to confirm it's the right one before you order.
