BSA Oil release valve body
An oil release valve body from the lubrication system, part number 70-9214.
This is an oil release valve body, listed under part number 70-9214. It shows up in the catalog under oil pump and gearbox sprocket figures, so it lives in the lubrication side of the engine rather than being a gearbox internal itself despite where it's filed.

A release valve of this type is generally there to bleed off excess oil pressure so the system doesn't build up beyond what the pump and feed lines are meant to handle. Beyond that, our record on this one is thin.
The catalog entry only ties it to a single year's listing, and we don't have enough detail here to say which specific models it was fitted to. Call the shop and we'll confirm fitment before you order.
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.
