CAM BUSH BSA
Timing-side camshaft bush for BSA unit-construction twins, listed under 68-0025 (also 57-0065 / T65).
This is a timing-side camshaft bush for the BSA unit-construction twins, listed in the catalog as CAM BUSH BSA. It sits in the timing-side crankcase where the camshaft rides, and it's a wear item that gets checked whenever someone's into the timing chest for an overhaul.

The part number 68-0025 also shows up under the older 57-0065 and T65 designations, so if your parts book or an old invoice references either of those, they're the same physical piece. Even though it lives in a BSA engine, it's carried in our catalog under a Triumph-prefix number, which is common for parts that cross-reference between the two makes' catalogs from this era.
Given where these live in the engine, get the actual bore and shaft measured before ordering rather than assuming from the book alone. Call the shop if you want us to talk through fitment on your specific case.
