Barnett clutch plates have long been associated with competition applications, and this friction driving clutch plate is manufactured to the highest quality available. Suitable for use in the BSA twins from 1966-1972 and Triumph twins from 1947-1983. This listing is for (1) friction driving clutch plate. Most applications require (6) friction plates.
Made in the US, the driving clutch plate has a steel body with bonded segments of Corprene, a durable material that offers excellent friction properties and wear resistance. The clutch plate measures .150″ thick across the bonded segments.
The clutch functions to transfer power from the engine to the transmission. The driving plates and plain steel driven plates are alternated within the clutch chainwheel and located by tabs that fit into corresponding grooves in the clutch center and clutch chainwheel. The tabs must be in good condition and free of burrs to allow free lateral movement of the plates. A total of (6) driving friction plates are used in the clutch chainwheel, in most applications.
The primary chaincase cover is removed to gain access to the primary drive system. Once the clutch spring nuts are free from the studs, the pressure plate can be removed, allowing access to the clutch plates. A magnet can be useful to help remove stubborn plates. Consult the workshop manual for the complete procedure.
