BSA SLUDGE TRAP TUBE A10 A65
Sludge trap tube for the BSA A10 and A65 engine, part number 67-1220.
This is the sludge trap tube listed for the BSA A10 and A65, part number 67-1220 (also seen in older records as 67-0122 or 67.122). A sludge trap sits inside the crankshaft and works as a centrifuge, catching debris and grit as oil is flung around during running, keeping the heavier contaminants out of the oil feed to the bearings and rods.

Because it's a BSA A10/A65 part per the catalog listing, it doesn't belong on a Triumph engine — the description is specific to those BSA twins. If you're rebuilding a crank and pulling the old trap tube, this is worth checking against your crankshaft before ordering, since sludge traps vary by engine family and generation.
We don't have much more detail on this one beyond what's in the catalog record. Give the shop a call if you want to confirm it matches your particular crank before you buy.
