Triumph 750 T140 TR7 Rocker Shaft Spindle 1973 On UNF PN# 71-3549 E13549

This rocker spindle is the correct shaft with 3/8″-24 TPI UNF threads for the 1973 and later Triumph 750 models, except the TSS model.

The rocker spindle is machined with the correct oilways and threaded for UNF rocker spindle nuts. Made in the UK by LF Harris.

The rocker spindle shaft supports the rocker arms and provides lubrication to the top end of the engine through the hollow oil passage from the rocker feed manifold.

The spindle passes through the rocker box cover and locates the rocker oil feed banjo fittings. The spindle cap is fitted with an o-ring to seal the rocker box after the securing nuts are tightened. 

Note: These do not fit Triumph TSS twins.

LF Harris motorcycle spares are produced to the highest quality standards possible utilizing original Triumph tooling, dies, factory blueprints & materials combined with modern manufacturing equipment, tolerances & techniques.
