Suitable fitment for pre-unit and early unit-construction Triumph twin forks fitted with steering damper assemblies, this split sleeve nut has an open top, allowing the damper rod to pass through the nut. Not compatible with early pre-unit 3T and 1960-1962 6T models with nacelle. Check your model year parts catalog for compatibility as there was some variations in specification.
Finished in corrosion-resistant zinc plating, this sleeve nut is threaded to 26 TPI CEI, with an approximate 1″ ID. Made in the UK.
The nut is split to allow for a very light interference fit within the fork top yoke. When threaded onto the steer stem and tightened, it pulls the lower and top fork yokes together to set the adjustment of the fork bearings.
Once the pre-load adjustment on the steering head bearings is achieved, the adjustment is secured by tightening the top yoke pinch bolt to hold the sleeve nut in place. A light smear of grease on the outer body of the nut will assist in rotation of the nut within the top fork yoke.
Note: This is the 26TPI split steering stem nut which was fitted up to 1968. As 1967/68 were years, we recommend verifying which thread pitch your stem has prior to ordering, see link below for the 28TPI version used 1967 onward.
