BSA Washer — cam plate plunger plug
Sealing washer fitted under the cam plate plunger plug in the crankcase.
This is the washer that seats behind the cam plate plunger plug down in the crankcase. It shows up in the crankcase and crankcase/generator figures, so it lives in the bottom end area where the gearbox cam plate plunger assembly is fitted. The plug it pairs with holds the plunger and spring against the cam plate detents, and this washer sits under that plug to seal the joint.

Our catalog listing carries this under 15-0203, with 15-203 as an alternate form of the same number. It's a small part but not one you want to skip when you're rebuilding that area — a missing or worn washer at the plug can let oil seep out around the plunger.
Our records don't tie this to a specific model or year beyond the catalog span noted, so if you're matching it up to a particular machine, give us a call and we'll confirm fitment before you order.
