Crankshaft Timing Chain Sprocket – TR5-6

Crankshaft timing chain sprocket suitable for TR5-6. Also fits Spitfire, 2000 & 2500. These components have a tendency to wear the teeth either due their age or a failure of either the timing chain or tensioner. It is critical to ensure that the teeth remain uniform and consistent, a badly worn sprocket will effect the timing figures of a cam. Made in England.
