How to Change a Throw Out Bearing: A Comprehensive Guide

If you're experiencing difficulties shifting gears or hearing strange noises coming from your clutch, you may need to change the throw out bearing. This critical component plays a vital role in disengaging the clutch, allowing you to seamlessly transition between gears. Replacing it can be a challenging task, but with the right tools and knowledge, it's achievable.

Basic Concepts of Changing Throw Out Bearing

The throw out bearing is a circular, metal part that rotates on the transmission input shaft. When you press down on the clutch pedal, the hydraulic system forces the bearing against the clutch pressure plate, which in turn disengages the clutch disc from the flywheel. This process enables you to change gears smoothly.

Advanced Features

Modern throw out bearings often come equipped with advanced features to enhance performance and durability. These include:

• Sealed bearings: Prevent contaminants from entering the bearing, extending its lifespan.
• Ceramic balls: Reduce friction and wear, improving shifting performance.
• Grease-filled: Provide lubrication for smooth operation and extended service intervals.

Changing Throw Out Bearing: Step-by-Step Guide

Tools Required:

• Jack and jack stands
• Transmission jack
• Wrench set
• Socket set
• Screwdriver
• Grease
• New throw out bearing

Steps:

1. Safety first: Park your vehicle on a level surface, engage the parking brake, and disconnect the battery.
2. Lift the vehicle: Use a jack and jack stands to raise the front of the vehicle and secure it safely.
3. Remove the transmission: Support the transmission with a transmission jack and unbolt it from the engine. Carefully lower the transmission and set it aside.
4. Locate the throw out bearing: The throw out bearing is typically located on the transmission input shaft. Identify it and disconnect the clutch fork from the bearing.
5. Remove the old bearing: Use a wrench to remove the retaining nut and slide the old bearing off the input shaft.
6. Inspect the input shaft: Check the input shaft for any damage or wear. If necessary, replace the shaft before installing the new bearing.
7. Install the new bearing: Apply a thin layer of grease to the new bearing and slide it onto the input shaft. Tighten the retaining nut to the specified torque.
8. Reattach the clutch fork: Connect the clutch fork to the new bearing and ensure it operates smoothly.
9. Reinstall the transmission: Carefully lift the transmission back into place and bolt it to the engine.
10. Reconnect the battery and test: Reconnect the battery and start the vehicle. Test the clutch to ensure it engages and disengages properly.

Common Mistakes to Avoid

• Using the wrong bearing: Ensure you purchase the correct throw out bearing for your vehicle's make and model.
• Skipping the inspection: Always inspect the input shaft for damage before installing the new bearing.
• Overtightening the retaining nut: Follow the specified torque guidelines to avoid damaging the bearing and shaft.
• Mixing grease types: Stick to the recommended grease type for the new bearing. Using incompatible grease can reduce its lifespan.
• Forgetting to lubricate the clutch fork: Apply grease to the clutch fork contact points to prevent wear and sticking.
