CAM BUSH L/H EARLY USA
Left-hand camshaft bush for early USA-spec Triumph crankcases, catalog part 71-0288A.
This is the left-hand camshaft bush, listed in the catalog as an early USA-spec piece, part number 71-0288A (also shown as 71-0288 in some listings). Cam bushes locate and support the camshaft ends in the crankcase, giving the cam a true bearing surface to run in as it opens and closes the valves.

Because this is called out specifically as an early USA version, it's not a one-size-fits-all bush across the model range — the catalog treats early USA-market crankcases as needing this particular number rather than a later or export equivalent. If you're rebuilding a set of cases, it's worth checking which side and which era bush you actually need before ordering.
We don't have a lot more written detail on this one beyond what's in the parts book. If you're not sure whether your cases take this bush or a later variant, give us a call with your crankcase or engine number and we'll sort out fitment before you order.
