Barnett clutch plates have long been associated with competition applications, and this plain steel clutch plate is manufactured to the highest quality available. Suitable for use in the 4-spring clutches used in the unit-construction BSA and Triumph single-cylinder models from 1959-1973. Not compatible with the Triumph T20 Cub models. This listing is for (1) or (6) steel clutch plate(s).
Made in the US, the driven plain steel clutch plate has a unique finish with tiny shallow indentations to enhance engagement with the driving friction plates. The plate measures .060″ thick.
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 (5) driven steel plates are used in the clutch chainwheel.
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.Â
