BSA BOTTOM VALVE SPRING CUP A10SR
Bottom valve spring cup for the BSA A10SR, part number 67-0886 (also B182B).
This is the bottom valve spring cup listed under BSA number 67-0886, also known by the older B182B designation. The catalog description ties it to the A10SR engine, and it's a valve train part rather than anything from the Triumph side of the shop.

A valve spring cup like this sits under the valve spring and gives it a proper seat against the cylinder head or spring retainer, keeping the spring aligned as it compresses and releases with each valve cycle. Beyond what the description tells us, we don't have more detail on this one in our records.
If you're sorting out valve gear on an A10SR, this is worth checking against your parts book before ordering, since our listing is brief and doesn't give us fitment notes beyond the model name in the description.
