PUSH ROD T140
Pushrod for the Triumph 750 unit twin (T140/TR7RV), running between tappet and rocker in the top end.
71-3330 is the pushrod for the 750cc unit twin engine, the T140 and TR7RV. It rides between the tappet and the rocker, transferring the lift from the camshaft up to the valve gear so the valves open and close on schedule. It shows up in the parts book under the cylinder block and head sections as well as the manifold and tappets figure, which tells you where it lives in the top end.

These wear at both ends where they seat against the tappet and the rocker adjuster, so if you're doing valve gear work it's worth pulling the old ones and checking for pitting or a bent rod before you put the head back together. Catalog records show this number appearing across cylinder head and tappet figures for the 750 twin from the mid to late '70s.
When you order, make sure you're getting the right count and matching set for your engine - these get sold and fitted as a set rather than piecemeal, so check what you already have before ordering just one.
