Clutch release bearing, also known as clutch throwout bearing, is an important component in the automotive transmission system. It is located between the clutch and the transmission, and its main function is to separate the clutch pressure plate from the friction disc when the driver depresses the clutch pedal, thus cutting off the power transmission from the engine to the transmission system. The release bearing ensures smooth clutch disengagement by eliminating the heat and resistance generated by direct friction, which is vital to the normal operation of the vehicle.

How the clutch release bearing works:

- When the driver depresses the clutch pedal, the release bearing pushes the pressure plate, separating it from the friction disc and interrupting power transmission.

- The release bearing seat is loosely fitted to the tubular extension of the transmission's first shaft bearing cover, and the convex shoulder of the release bearing is always pressed against the release fork by the return spring and backed up to its final position, maintaining a clearance of about 3~4mm with the end of the release lever.

- The movement of the release bearing should be flexible without sharp rattling or jamming, its axial clearance should not exceed 0.60mm, and the wear of the inner seat ring should not exceed 0.30mm.

Clutch release bearing replacement cost:

The cost of replacing a clutch release bearing varies depending on a number of factors, including vehicle make and model, location, labour hours, and cost of parts. In the United States, the average cost to replace a clutch release bearing can range from $200 to $500, but this is only a general range.

Generally speaking, the clutch release bearing replacement cost for vehicles in China is roughly between RMB 1,200-1,600, and if you choose to have it done at a professional workshop, you may be able to enjoy a more affordable price of around RMB 900-1,200. For imported models, the repair cost will be slightly higher, around RMB 1,600-2,200. This is mainly due to the fact that different makes and models of cars may require different parts, and parts for discontinued models are often difficult to find, increasing the repair cost.

In some cases, the cost may be higher if more parts need to be removed to access the release bearing, or if the vehicle is a premium brand.

It's important to note that when a release bearing fails, it can affect the overall performance of the three-piece clutch package, which includes the pressure plate, friction disc and release bearing. Therefore, when replacing the release bearing, the service personnel will usually recommend simultaneous inspection and consider replacing the clutch three-piece set to ensure the proper operation of the vehicle. This may increase the overall repair cost accordingly.

Summary:

The clutch release bearing is an important part that ensures proper clutch operation, and its replacement cost is affected by a number of factors, including the type of vehicle, the region where it is located, and the cost of labour hours. In order to obtain an accurate replacement cost, vehicle owners are advised to consult a professional repair shop or a repair centre authorised by the vehicle manufacturer.

Regular inspection and maintenance of the release bearing can avoid sudden breakdowns and reduce unnecessary financial losses. If the release bearing fails, timely replacement is necessary to ensure the normal operation of the vehicle and driving safety.
