CAM BUSHING SHORT EX UK - Replaces 70-1516
Short camshaft bushing for the crankcase, UK-spec version, replaces the earlier 70-1516.
71-0287 is a camshaft bushing that lives in the crankcase, per the parts book listing. It's the short version, marked EX UK in the catalog, which tells us this particular bushing was sourced or specified for the UK market rather than as a universal part.

This number replaced the earlier 70-1516 in Triumph's records, so if you're working from an older parts book or pulling a bushing off a motor built before the changeover, you may see that number instead. Both refer to the same physical bushing.
The catalog shows this part appearing across a run of years in the 1970s crankcase listings. Camshaft bushings support the camshaft in the crankcase and take wear over time from rotation and oil film condition, so if you're rebuilding down in that area it's worth checking the bore and the bushing fit rather than assuming the old one is still good.
