Outer cover – gearbox, with oil seal, bushes and studs

Outer gearbox cover assembly with oil seal, bushes, and studs, covering the gearchange and kickstart crank area.

PN · 57-2737

This is the outer gearbox cover for the unit-construction Triumph gearbox, listed with its oil seal, bushes, and studs included as a set. It sits on the outside of the gearbox shell and closes off the area where the gearchange mechanism and kickstart crank operate, so it takes wear from both the shift lever and the kickstart shaft passing through it.

Because it comes through with the oil seal and bushes already called out, this is meant to be a complete cover assembly rather than just a bare casting - useful if you're dealing with a cover that's worn oval at the bushing bores or leaking past the seal. The catalog only ties this part to one model year in our records, so if you're matching it against an older or newer gearbox shell, best to check the fit before you bolt it up.

We don't have a lot more detail on this one beyond what's in the figure title and description. Call the shop if you want us to confirm it against your specific gearbox casting before ordering.
