PRIMARY GASKET A10
Primary chaincase gasket cataloged for the BSA A10, also known as GAS 36 / GAS-36.
This is a primary chaincase gasket listed in our records as PRIMARY GASKET A10. The A10 designation in the description points to a BSA A10 application, not a Triumph, even though this number lives in our Triumph-numbered catalog system. It also shows up under the older GAS 36 / GAS-36 reference.

A primary gasket like this seats between the inner primary cover and the crankcase (or between inner and outer covers, depending on the joint it's cut for) to keep the primary chaincase oil where it belongs. We don't have more detail on this one beyond the description and the alternate part numbers it's cataloged under.
Given the A10 callout, confirm this is the gasket your BSA A10 primary case needs before ordering — call the shop if you want us to check it against your bike.
