Installation Method for Clutch Release Bearing of Hyundai and Mitsubishi Vehicles

1. Pre-Installation Preparation

1.1 Safety and Tool Preparation

• Park the vehicle on a flat surface, turn off the engine, engage the parking brake, and disconnect the negative battery terminal to prevent short circuits.

• Prepare tools: socket wrench (10-19mm), torque wrench, circlip pliers, flathead screwdriver, cleaning agent (alcohol or carburetor cleaner), high-temperature grease (meeting vehicle manual specifications, e.g., Hyundai recommends SP-4 grade, Mitsubishi recommends MP-3 grade), and rubber mallet.

1.2 Accessory and Component Inspection

• Confirm the release bearing model matches the vehicle (e.g., Hyundai Elantra corresponds to bearing number 41421-26000, Mitsubishi Outlander corresponds to MD755246). Check that the bearing rollers have no jamming or abnormal noise, and the sealing ring is intact.

• Clean the clutch release fork (Hyundai mostly uses resin material, Mitsubishi partially uses metal material) and the contact surface of the release bearing seat. Remove oil stains and rust; if the fork is worn or deformed, replace it simultaneously.

2. Remove the Old Release Bearing (If Not Completed in Advance)

• Remove the transmission according to the vehicle manual (Hyundai requires removing the clutch slave cylinder push rod first, Mitsubishi requires loosening the release fork fixing bolt first) to expose the clutch pressure plate and release fork.

• Use circlip pliers to remove the circlip connecting the release bearing and the fork (Hyundai mostly uses elastic retainer rings, Mitsubishi partially uses bolt fixing), or loosen the fixing bolt to remove the old bearing from the fork.

• Clean the fork installation position: wipe the guide surface where the fork contacts the bearing with a cleaning agent, remove residual grease and debris, and check that the fork has no cracks or excessive wear.

3. Universal Installation Steps (Applicable to Both Hyundai and Mitsubishi)

3.1 Pre-Treatment of the Release Bearing

• Apply a thin, even layer of high-temperature grease to the inner ring of the release bearing (the sliding surface in contact with the fork). Be careful not to let the grease flow into the bearing interior (to prevent contamination of the clutch friction disc after melting at high temperatures).

• Some Hyundai models (e.g., Sonata) require installing a dust cover on the outer ring of the bearing, while some Mitsubishi models (e.g., Pajero) require placing a buffer gasket in the bearing seat. Restore the original vehicle structure as required.

3.2 Assembly to the Release Fork

• Align the release bearing with the guide groove of the fork, and gently push or sleeve it into place (avoid excessive force on Hyundai’s resin fork to prevent breakage; Mitsubishi’s metal fork can be tapped into place lightly).

• Fix the bearing: For Hyundai models, use circlip pliers to install the elastic retainer ring, ensuring it is fully engaged in the fork’s groove. For some Mitsubishi models, use a torque wrench to tighten the fixing bolt (torque is usually 8-12N·m, subject to the manual) to prevent bearing loosening.

3.3 Alignment with the Clutch Pressure Plate

• Push the release fork and check if the release bearing can smoothly contact the pressure plate’s release fingers (Hyundai’s pressure plate release fingers are mostly evenly distributed in 3 points, while some Mitsubishi models use 4 points). Ensure there is no jamming or deviation, and the bearing is fully fitted to the contact surface of the release fingers.

• If the Hyundai model is equipped with a clutch stroke sensor, adjust the bearing position to ensure the gap between the sensor probe and the bearing seat meets requirements (usually 0.5-1mm) to avoid abnormal signals.

4. Model-Specific Details (Hyundai vs. Mitsubishi)

5. Reassembly and Testing

• Reinstall the transmission according to the manual requirements. For Hyundai, first connect the clutch slave cylinder push rod and adjust the free travel (15-20mm); for Mitsubishi, reset the release fork fixing bolt and check the fork’s movement range.

• Connect the negative battery terminal, start the engine, and press the clutch pedal 3-5 times to bleed air from the hydraulic system (Hyundai’s hydraulic clutch) or run-in the mechanical stroke (some of Mitsubishi’s mechanical clutches).

• Testing: Press and release the clutch pedal at idle speed, and listen for "buzzing" abnormal noise (a sign of bearing failure); engage all gears and check if shifting is smooth, with no incomplete disengagement (gear shifting jamming) or overly soft engagement (weak pedal feel).

Core Precautions

• Grease dosage: Apply only a thin layer to the contact area between the bearing and the fork; excessive grease will be thrown onto the friction disc, causing slipping.

• Accurate alignment: The bearing must be fully centered with the pressure plate’s release fingers. Misalignment of Hyundai’s resin fork may cause breakage, while misalignment of Mitsubishi’s metal fork will accelerate bearing wear.

• Synchronous inspection: During installation, simultaneously check the clutch release bearing seat (Hyundai mostly uses plastic, which is prone to aging) and Mitsubishi’s fork bushing. Replace them if damaged to avoid secondary maintenance.
