Mercedes-Benz (Taking Hydraulic Clutch as an Example, Common in Most Domestic Mercedes-Benz Passenger Vehicles)

1. Pre-Installation Preparation

• Lift the front of the vehicle with a jack and secure it with safety stands. Disconnect the negative terminal of the car battery to avoid short circuits.

• Prepare tools such as wrenches and torque wrenches. Verify that the new release bearing matches the specifications, is free from damage, and rotates smoothly.

2. Assembling Release Bearing Components

• If the release bearing is integrated with the slave cylinder:

1. Clean the outer housing of the slave cylinder.

2. Immerse the new seal ring in brake fluid and install it on the piston, ensuring the working edge of the seal ring faces the spring side.

3. Apply clean brake fluid to the cylinder bore, install the spring (with the large-diameter coil end facing the rear of the cylinder body), and smoothly push the piston into the cylinder bore.

4. Finally, install the push rod with dust cover and secure it with a circlip.

3. Installation to Clutch Housing

• Install the slave cylinder gasket with the notched side facing the clutch housing.

• Mount the slave cylinder (with push rod) into the housing, ensuring the push rod fits into the spherical groove of the clutch release lever. Secure the slave cylinder with bolts.

4. Post-Installation Procedures

• Connect the hydraulic oil pipe, fill the clutch hydraulic system with compatible brake fluid, and bleed air from the system.

• Reconnect the negative terminal of the battery. Start the vehicle to test gear shifting smoothness, and check for oil leaks, abnormal noises, or other irregularities.

A. Manual Transmission Models (e.g., Bora, Sagitar 1.6, etc.)

1. Preprocessing

• Lift and secure the vehicle. Remove peripheral components such as the battery, air filter, and starter motor in sequence. Then remove the tires, control arm bolts, drive shaft, and finally the bolts and mounts connecting the transmission to the engine. Lower the transmission to expose the release bearing.

2. Bearing Installation

• Clean the release sleeve and mounting contact surfaces. Apply an appropriate amount of grease to the surface of the new release bearing.

• Slide the new release bearing onto the release sleeve (ensure correct installation direction), then install the assembled release sleeve and bearing onto the transmission input shaft.

3. Reset and Debugging

• Install the clutch fork to ensure precise alignment with the release bearing.

• Use a special tool to align and fix the clutch disc and pressure plate. Lift the transmission back into position and reinstall all components (drive shaft, tires, etc.) in reverse order.

• Start the vehicle to test the normal engagement and disengagement of the clutch.

B. 7-Speed Dry Dual-Clutch Transmission (e.g., DQ200 Gearbox)

1. Installing Forks and Bearings

• First install the K2 clutch release fork, and tighten the fixing bolts to 8 N·m with a torque wrench.

• Then install the K1 clutch release fork, place the corresponding adjusting shim according to the specification of the original old shim, and sequentially install the K2 and K1 release bearings.

2. Gap Adjustment

• Use a special measuring tool to check the gaps: the standard gap for K1 is approximately 1.0mm, and for K2 is approximately 0.6mm.

• If the gap does not meet the standard, replace the adjusting shim with the corresponding thickness until the gap is within the specified range.

3. Fixing and Matching

• Use a special tool to press-fit the dual-clutch assembly onto the input shaft and secure it with a circlip.

• Join the transmission to the engine. Turn on the ignition switch, access the transmission system via the diagnostic tool, and perform adjustment matching through Group 60.

• After the data meets the requirements, start the vehicle and test the smoothness of gear shifts.

Precautions for Installing Clutch Release Bearings on Mercedes-Benz and Volkswagen Vehicles

I. General Core Precautions

1. Component Compatibility Verification

• The new clutch release bearing must be fully compatible with the vehicle model and transmission type (e.g., the Volkswagen DQ200 transmission requires a dedicated release bearing, and the Mercedes-Benz hydraulic clutch bearing must match the slave cylinder specifications). Verify that the part number is consistent with the original factory to avoid installation interference or functional failure due to mismatched models.

• Inspect the new bearing for no scratches, rust, jamming, or abnormal noise during rotation, and ensure the seal ring is intact and undamaged. Use original factory or equivalent specifications for supporting parts (such as gaskets, circlips, and seal rings); mixing gaskets of different materials is strictly prohibited.

2. Installation Environment and Tool Specifications

• The operating site must be clean and dry to prevent dust and oil from entering the clutch housing or hydraulic system. Use special tools for disassembly/installation (e.g., Volkswagen dual-clutch gap measuring tool, Mercedes-Benz hydraulic slave cylinder pressing tool). Do not directly strike the bearing outer ring or fork with a hammer to avoid component deformation.

• Calibrate the torque wrench in advance. Critical bolts (such as transmission fixing bolts and fork fixing screws) must be tightened according to the original factory torque standards (reference values: Volkswagen fork screws 8N·m, Mercedes-Benz slave cylinder fixing bolts 12-15N·m). Avoid loose bolts causing abnormal noise or over-tightening damaging the threads.

3. Lubrication and Cleaning Requirements

• Thoroughly clean the release sleeve, fork contact surfaces, and input shaft journal before installation to remove oil, rust, and old grease. Ensure no impurities on the mounting surfaces affect the fit.

• Apply a small amount of high-temperature grease only to the sliding contact surface between the bearing and the fork (recommended to use the original factory-specified model, such as Volkswagen G005000, Mercedes-Benz 0019892502). Do not apply grease to the bearing's internal balls or clutch friction plate to prevent slipping and failure.

4. Safe Operation Specifications

• When lifting the vehicle, must fix it bidirectionally with safety stands; do not rely solely on a jack for support during operation. After disconnecting the negative battery terminal, wait 10-15 minutes to ensure the circuit is fully powered off, avoiding short circuits during disassembly.

• Before removing the transmission, drain the clutch hydraulic oil (for Mercedes-Benz) or mark the pipeline positions to prevent oil pipe distortion and leakage. After installation, promptly refill with the corresponding type of oil (Mercedes-Benz uses special brake fluid, Volkswagen manual transmission uses clutch fluid G004000) and bleed air from the system in accordance with specifications.

1. Original Factory Maintenance Technical Specifications of Volkswagen and Mercedes-Benz

• Details in the text such as the installation torque, gap standards (K1: approximately 1.0mm, K2: approximately 0.6mm), and fork installation sequence for Volkswagen's DQ200 7-speed dry dual-clutch transmission are consistent with the core maintenance points mentioned in the practical tutorials for DQ200 transmission clutch replacement on Douyin, including the 8 N·m torque and shim gap adjustment.

• Operations like diagonally tightening the pressure plate bolts of manual transmission models and positioning the clutch disc with special tools also match the general installation specifications for clutch kits published on platforms such as PCauto.

• Steps related to Mercedes-Benz's hydraulic clutch, such as the integrated installation of the release bearing and slave cylinder, hydraulic system bleeding, and seal ring installation, align with the general logic of hydraulic clutch release bearing installation on platforms like Autohome. Key requirements include soaking seals in oil for softening and fully bleeding air from the hydraulic system.

2. General Practical Experience in the Automotive Repair Field

• General precautions in the text, such as verifying bearing specifications before installation, securing the vehicle with safety stands, tightening critical bolts to factory torque standards, and avoiding clutch friction plate contamination by grease, are mentioned in multiple articles related to clutch release bearing installation on platforms like Autohome and PCauto.

• These are common requirements for the installation of precision transmission systems such as clutches in the automotive repair industry, serving as the basic guidelines to ensure the normal operation of the vehicle after installation.
