Clutch rod bush
Clutch pushrod mainshaft bush for the gearbox on unit-construction Triumph twins, keeps the clutch rod centered as it passes through the mainshaft.
This is the clutch rod bush, sometimes called the mainshaft split bush, that lives inside the gearbox mainshaft on unit-construction Triumph twins. It supports the clutch pushrod where it passes through the mainshaft, keeping the rod running true instead of wallowing around in the bore as the clutch is actuated. Catalog listings put it in the gearbox shafts and gear cluster figures, right alongside the timing cover work.

The part shows up under a few names across the years - the old book form is T1391, and it's also listed as 9368T42 - but they're all the same physical bush. If you're chasing clutch pushrod slop, a worn drag on clutch feel, or gearbox rebuild parts on a unit twin, this is a small item worth checking while the cover's off.
Our catalog record spans a run of years across the 1960s and into the mid-1970s, appearing in fifteen separate listings, so it was used across a good number of gearbox builds in that era. Because fitment can vary by mainshaft type, confirm the bush matches your mainshaft before ordering.
