Chain Primary Drive Clutch
A chain drive version of our belt drive clutch, not an absolute copy of an original but an updated and improved version that integrates right into a chain primary drive set up.
42 tooth drum to suit 1/2" x 5/16" chain as fitted to Primary Drive`s on all things British including Manx Norton AJS 7R and Matchless G50. Centre is machined to fit all AMC gearbox mainshafts and later derivatives (Quaife, TTI etc)
The standard centre requires a minimum of 22mm of mainshaft spline length to fit correctly.
6 spring clutch, fitted as standard with steel plates & bonded fibre plates, however we can supply the clutch with alloy plates & lightweight fibre plates.
The drum is made from Hard Anodised Aluminium, whilst the centre and pressure plate is self colour aluminium. We HIGHLY recommend you opt to have the drum lightened to improve dust clearing, and the pressure plate can also be lightened.
Drum Lightening Saves 105g
Pressure Plate Lightening Saves 80g
Alloy Plates Save 315g
