The clutch throw out bearing, also known as a “throw block bearing” or “throw out bearing”, is a critical component in the manual transmission of an automobile. It is located between the clutch pressure plate and the flywheel, and its main function is to push the release bearing through the release fork when the driver depresses the clutch pedal to separate the clutch pressure plate from the flywheel, thus interrupting the power transmission between the engine and the transmission. Due to long-term friction and pressure, the release bearing may wear out or fail, leading to problems such as difficult clutch operation and unusual noise.
- Make sure the vehicle is in a horizontal position and prepare appropriate tools such as wrenches, screwdrivers, sockets, jacks, safety stands, etc.
- Prepare the new release bearing and other parts that may be required (e.g. clutch plates, pressure plate, etc.).
- Raise the vehicle using a jack and support it with safety stands to ensure safety.
- Remove tires, wheels, brakes, etc. to access the transmission.
- Disconnect wires, fuel lines, etc. associated with the clutch.
- Remove drive shaft and transmission connection to engine.
- Remove the clutch pressure plate, release lever, and old release bearing.
- Clean the related parts to ensure that there are no impurities.
- Install the new release bearing, making sure it is properly aligned and secured.
- If necessary, replace the clutch disc and pressure plate at the same time, as these parts tend to wear together.
- Reinstall the clutch pressure plate, release lever, etc., in the reverse order of disassembly.
- Restore all connections, including driveshaft, gearbox to engine.
- Lower the vehicle, start the engine and test the clutch operation for smooth operation and no abnormal sound.
- Check for oil leakage around the clutch system and make sure all seals are installed correctly.
- Adjust the clutch pedal travel to the specified range to ensure smooth clutch release and engagement.
The cost of replacing the clutch release bearing varies depending on a number of factors, including the following:
- Release Bearing: The price of a new release bearing varies by model and brand, usually ranging from a few dozen to several hundred RMB. For high-end models or special configurations, the cost of parts may be higher.
- Other parts: If other parts such as clutch plates and pressure plates need to be replaced at the same time, additional parts costs will be incurred. The cost of these parts may range from a few hundred dollars to thousands of dollars, depending on the model and brand.
- Labor hours are one of the major costs of the replacement process because it involves multiple steps and specialized skills. The labor cost is usually calculated based on the technician's labor rate and the time required for the replacement. At a 4S store or specialty repair shop, the hourly rate may be higher than an outside shop. The average labor hourly rate is around RMB 120 to RMB 300 per hour and the whole process may take 4 to 10 hours, so the labor hourly rate may range from RMB 480 to RMB 3,000.
- Diagnostic fee: If the problem has not been identified before, additional diagnostic fee may be required. Diagnostic fees usually range from 100 to 500 RMB.
- Additional Repair Costs: Additional repair costs will be incurred if other damaged parts (e.g. clutch plates, pressure plates, etc.) are found during the replacement process.
- Lubricants and other consumables: Although most modern designs of release bearings do not require direct lubrication by the user, in some cases it may be necessary to replace the lubricants or other consumables, which will also add some costs.
Taking all these factors into account, the overall cost of replacing a clutch release bearing may range from a few hundred to a few thousand RMB, depending on the following factors:
- Vehicle model: The cost of parts and labor varies greatly from model to model, with higher-end models usually costing more.
- Repair location: 4S store costs are usually higher than ordinary repair shops, but the quality of service and technical level is also relatively more secure. Parts brand: choose different brands of parts and labor hour costs, high-end models are usually more expensive.
- Parts brand: choose different brands of parts will affect the price, the original parts are usually more expensive than the sub-factory parts.
- Whether to replace other parts: If you need to replace the clutch plate, pressure plate and other parts at the same time, the cost will increase significantly.
1. Choose a suitable workshop: Although 4S stores provide original parts and professional services, they are more expensive. You can choose a reputable independent garage, the cost is usually lower.
2. Purchase parts by yourself: If you have some mechanical knowledge, you can purchase parts by yourself and choose the garage to install them, which can save part of the cost of parts.
3. Regular maintenance: Regular inspection and maintenance of the clutch system, timely detection and treatment of problems can extend the service life of the components and reduce the frequency and cost of major repairs.
Replacement of clutch release bearing after replacement
- The newly installed release bearing needs a certain break-in period to avoid overly aggressive driving during initial use, which may cause early wear. It is recommended to keep driving gently in the first few hundred kilometers after replacement, avoiding frequent sharp acceleration and hard braking.
- When using a new release bearing, avoid prolonged semi-linkage state to reduce unnecessary clutch pedal shaking to prolong the service life of the clutch.
- Pay attention to whether the clutch pedal feels normal or not. If there is any abnormality (e.g. too heavy pedal, too long or too short stroke, abnormal noise, etc.), the clutch system should be checked immediately.
- Check whether there is any hydraulic oil leakage in the clutch system.
- During driving, watch for abnormal noise, such as noise that may be generated by improperly installed release bearings.
- Regularly check the condition of the release bearing and the entire clutch system according to the manufacturer's recommended maintenance intervals to ensure that it is working properly.
- Adopt good driving habits and avoid frequent hard acceleration and hard braking to reduce the wear of the clutch.
- Pay attention to the working temperature of the clutch. If the clutch is found to be overheated, it should be stopped and inspected to avoid clutch failure caused by overheating.
- Record the date of release bearing replacement and mileage for future maintenance and care.
- If you have any questions during the break-in period or use, you should consult a professional automotive service technician.
Summarize.
Replacing the clutch release bearing is one of the necessary maintenance to ensure the proper functioning of the clutch system of a manual transmission vehicle. The replacement process requires a certain degree of skill and experience and is usually recommended to be performed by a professional. By following the above steps and precautions, vehicle owners can ensure that clutch release bearing replacement goes smoothly and extends the service life of the clutch system. Timely replacement of the release bearing can prevent further damage and ensure a smooth and safe driving experience.
Choosing a high-quality release bearing and professional repair service is a smart move for both car manufacturers and car owners to ensure vehicle performance and enhance customer satisfaction.
The cost of replacing a clutch release bearing varies depending on a number of factors, mainly including the cost of parts, labor hours, and other possible additional costs. The overall cost may range from a few hundred to several thousand RMB, depending on the car model, repair location, brand of the part and whether other parts need to be replaced. To save money, vehicle owners can choose the right workshop, purchase the parts themselves and perform regular maintenance. Timely replacement of the release bearing can prevent further damage and ensure a smooth and safe driving experience.
