Clutch Release Bearings

The clutch release bearing is installed between the clutch and the transmission, and the release bearing seat is loosely sleeved on the tubular extension of the first shaft bearing cover of the transmission. The shoulder of the release bearing is always against the release fork through the return spring, and retreats to the rearmost position, maintaining a gap of about 3~4mm with the end of the release lever (release finger).

Since the clutch pressure plate and release lever operate synchronously with the engine crankshaft, and the release fork can only move along the axial direction of the clutch output shaft, it is obviously not possible to directly use the release fork to pull the release lever. The release bearing can make the release lever move along the axial direction of the clutch output shaft while rotating, so as to ensure that the clutch can be smoothly engaged, gently separated, reduce wear and prolong the service life of the clutch and the whole transmission system.

The clutch release bearing shall move flexibly without sharp noise or jamming, and its axial clearance shall not exceed 0.60mm, and the wear of the inner race shall not exceed 0.30mm.
