BSA Washer — crankcase bolt
A crankcase bolt washer, part number 75-0156, used in the crankcase and generator area of the engine.
This is a washer that sits under a crankcase bolt, part number 75-0156. It shows up in the crankcase and generator area of the parts book, doing the plain job a washer does at that joint — spreading load under the bolt head and keeping things seated as the crankcase halves and generator mounting come together.

Our catalog record on this one is thin. We see it appear twice in the books, spanning 1971 to 1972, tied to the crankcase and generator figure, but we don't have more detail on it beyond that.
If you're rebuilding a bottom end and need to match this washer up, bring in your old one or give us a call and we'll confirm fitment before you order.
