Joint washer
A joint washer for the primary chaincase area, later superseded by 57-1770.
This is the joint washer that sits in the primary chaincase area, listed in the parts book under the CHAINCASE AND CHAINS figure. It's a gasket-type piece meant to seal a joint in that assembly and keep oil where it belongs rather than seeping out around a mating surface.

On the older side of the parts books this one carries the alias E11463, and the catalog shows it was later superseded by 57-1770 — so if your bike's book or an older parts list calls for 71-1463 or E11463, that's the same physical piece as 57-1770 today.
We don't have detailed dimensions or material spec on hand for this one. If you're ordering, have your engine or chaincase numbers ready and we can confirm it's the right joint washer for your setup before it ships.
