TIMING SIDE BUSH BSA A65
Timing side crankcase bush for BSA A50/A65 engines, also known by its older B316 reference.
This is a timing side bush for BSA A50 and A65 engines, not a Triumph part despite where it landed in our numbering. The catalog description is plain on this one: it's a bush that lives on the timing side of the crankcase, supporting the crankshaft where it rides in the timing side of the motor. The old book alias for this part is B316, so if you're working from an older parts list and see that number, it's the same physical piece.

We don't have a lot of extra detail on file for this listing beyond the description itself. If you're rebuilding a BSA A50/A65 bottom end and need the timing side bush, give us a call and we'll confirm what you've got before it ships.
Bushings like this wear over time and play a role in keeping the crankshaft properly supported and aligned in the case, so it's a common item to check during a rebuild.
