OIL SEAL CRANK D/S BSA A10/A65 - NORTON GEARBOX SEAL - Replaces 040132
Crankshaft drive-side oil seal for BSA A10/A65, also used as a Norton gearbox seal, PN 67-0674.
This one is not a Triumph part, despite where it shows up in our numbering. The catalog description points to a BSA A10/A65 crankshaft drive-side oil seal, and the same part also gets called out as a Norton gearbox seal. So it's a seal that does double duty depending on which bike book you're reading from.

Our records show it crossing over to part number 04-0132, so if you've got an older parts list or a newer one, you may see either number for the same physical piece. We don't have much more detail beyond that on file, so if you're matching this up to a specific gearbox or crankcase, give us a call and we can confirm before you order.
If you're chasing an oil leak at a crankshaft drive-side or a Norton gearbox, this is worth checking against what's currently in there before you commit to a number.
