Norton Oil Seal, Kickstart Shaft
Oil seal for the kickstart shaft on a Norton gearbox outer cover, PN 06-6145.
This is the oil seal for the kickstart shaft on the gearbox outer cover, part number 06-6145. It sits where the kickstart shaft passes through the gearbox outer cover, keeping gearbox oil in and dirt out at that point of entry.

The catalog record we have ties this part to 1975 and the gearbox outer cover and kickstart figure. Given the manufacturer listed and the description referencing the kickstart shaft rather than any Triumph gearbox terminology, this looks to be a Norton part, not a Triumph one - so if you're working on a Triumph gearbox, this isn't your seal. Confirm against your own parts book before ordering.
It's a small, simple item, but a seal like this is what stands between a dry gearbox and an oily boot, so it's worth replacing anytime the outer cover comes off.
