BSA Inner timing cover with fixed fittings
Inner timing cover with fixed fittings for the gearchange mechanism, cataloged for 1971-1972 BSA A65 twins.
The 71-2277 is an inner timing cover, the plate that sits behind the outer timing cover and carries the fixed fittings for the gearchange mechanism. Catalog records place it in the 1971-1972 window, and the figure title ties it specifically to the gearchange side of the timing chest rather than the ignition or oil pump side.

This is a BSA part rather than a Triumph one - the catalog title on file for this number references the A65 twin, not a Triumph model. If you're working on a Triumph and this number turned up in your parts book by mistake, double check the figure before you order.
Because it's described as carrying "fixed fittings," expect this cover to come with certain hardware or bushings already fitted rather than as a bare plate. Confirm exactly what's included before ordering, since our record doesn't spell out every piece.
Sorry if we got something wrong here. If you think this information isn't correct, .
