Exhaust camshaft bush
Exhaust camshaft bush for the crankcase, also known as E1516, later superseded by 71-0287.
70-1516 is the exhaust camshaft bush that lives in the crankcase, supporting the exhaust camshaft where it rides in the case casting. It's a Triumph part, and the catalog record for it spans a run of years across several catalog listings, but the record we have doesn't tie it to a specific model, so we'd want to confirm fitment against your engine before ordering.

This one also shows up under the older E1516 form, which is the legacy letter-prefix number for the same physical bush. Further down the line the factory renumbered it again to 71-0287, so if your parts book or an old invoice shows either of those numbers, you're looking at the same piece.
A camshaft bush like this one is a wear item that keeps the cam running true in its bore and controls the running clearance. If you're rebuilding a bottom end and pulling the camshafts, it's worth inspecting the bores for wear before deciding whether to replace it. Call the shop if you want us to confirm which of the three numbers matches what's in front of you.
