TRUNNION,3CYL THROTTLE

Throttle linkage trunnion for Triumph/BSA three-cylinder triples, pivots the throttle rod at the carb gantry.

PN · 70-9243

This is the trunnion that lives in the throttle linkage on the three-cylinder Triumph/BSA triples. It's the small pivoting fitting that lets the throttle rod connect to the gantry linkage that runs across the bank of three carburetors, taking up the angle change as the rod moves and the throttle opens and closes.

The part number 70-9243 also shows up in older records as E9243, same physical piece under the earlier prefix style. It's a small component but a working one, and gantry linkages depend on trunnions like this staying free and not worn oval, or you'll feel it in sloppy or uneven throttle response across the three carbs.

We don't have a lot more written detail on this one beyond what's in the parts books. Sold each, not in a set, so check how many your linkage actually calls for before you order.
