Mainshaft bearing

A mainshaft bearing for the gearbox side of the engine, cataloged as 70-8014 (earlier reference E8014).

PN · 70-8014

70-8014 is a mainshaft bearing that Ed's records tie to the gearbox side of the engine, showing up in crankcase and gear cluster figures. It's part of what carries and locates the mainshaft as it spins, so it takes the load from the gearbox side of the drivetrain.

The older book reference for this one is E8014, so if you're working from an early parts list and see that number, it's the same physical bearing under a different catalog era.

Our records show this part across catalog entries running from 1968 into 1971, but we don't have a breakdown of which specific model or engine size it was fitted to within that span. If you're not sure this is the right bearing for your gearbox, give the shop a call and we'll help confirm before you order.
