Primary Pinion Bearing for the manual gearbox, supporting the primary pinion (gearbox input shaft). The primary pinion transmits drive from the clutch into the gearbox. This bearin g carries the shaft and locates it within the gearbox casing, allowing it to rotate with minimal friction and end-float. A worn bearing produces noise and play and should be renewed during a gearbox overhaul. Show more
