BSA Oil pump scavenge gear, driver
Driver gear for the oil pump scavenge side, turning the scavenge gear to pull oil back from the crankcase.
71-1144 is the driver gear for the scavenge side of the oil pump. This is the gear that gets turned by the pump drive and in turn spins the scavenge gear inside the pump body, pulling oil back out of the crankcase and up to the tank so it doesn't collect down below and get thrown around by the crank.

Our catalog record only ties this one appearance to the oil pump and gearbox sprocket area, with nothing more specific in terms of which model or year it was fitted to beyond the one entry we have on file. If you're matching this against a pump you've got on the bench, check the tooth count and shaft fit against your existing gear before you order.
Given how thin our records are on this part number, give the shop a call and we'll help confirm fitment before you commit to buying one.
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.
