BSA Plate — cush drive retaining, inner
Inner retaining plate for the cush drive assembly inside the primary chaincase.
This is a retaining plate for the cush drive assembly in the primary chaincase, listed in the parts books as the inner plate. It shows up in the clutch and primary cover figures, which puts it right in the area where the engine sprocket, primary chain, and clutch basket all live together behind the primary chaincase cover.

The cush drive setup uses rubber (or similar) segments to soften the driveline shocks that come through the primary chain, and the retaining plates on either side keep that assembly located and contained. This inner plate is the one that sits toward the engine side of that stack.
Our catalog record ties this part number to appearances across several years' worth of parts book listings, but we don't have more detail on it beyond that. If you're rebuilding a primary chaincase and need to know exactly how this plate stacks up with the other cush drive components, bring in what you've got or give us a call and we'll work through it with you.
We've never carried this one. Tell us what you're after and we'll go looking — you'll get a price and photos before you commit to anything.
