The installation process of the clutch friction plate for Mitsubishi vehicles shares commonalities with most fuel-powered cars. However, models like the Pajero have specific torque standards and installation marking requirements. Below is a detailed installation method tailored to Mitsubishi vehicles. It is recommended to refer to the corresponding vehicle's service manual during operation:
Vehicle Fixation and Protection: Park the vehicle on a flat surface, engage the handbrake, and secure the wheels with wheel chocks. Disconnect the battery's negative terminal to prevent short circuits. Lift the vehicle with a jack and support it stably with safety stands—never rely solely on the jack to avoid vehicle slippage. Finally, remove the engine splash shield to facilitate access to transmission components later.
Tool and Accessory Preparation: Prepare socket wrenches, a torque wrench, a clutch kit (including friction plate, pressure plate, release bearing), lithium-based grease, cleaning cloths, and a dedicated alignment tool. Confirm that the new friction plate is compatible with the corresponding Mitsubishi model, and check that the friction plate is free of cracks, oil contamination, spline wear, and other issues.
Removal to Expose the Clutch Assembly: First, disconnect connecting components such as the shift cables and clutch oil lines. Use socket wrenches to remove the transmission mounting bolts, then use a lifting tool to smoothly separate and lower the transmission, exposing the clutch assembly. Subsequently, remove the clutch cover bolts and take off the old pressure plate and friction plate.
Thoroughly clean oil stains, metal shavings, and rust from the surfaces of the flywheel and pressure plate with a cleaning cloth. Check the flywheel for scratches and warpage, and inspect the pressure plate's diaphragm spring for fatigue deformation—replace any defective components promptly. Additionally, check the wear condition of the transmission input shaft splines and add lubricating oil to the pilot bearing on the flywheel.
Positioning the Friction Plate: For Mitsubishi's clutch friction plates equipped with a damping disc, the side with the damping disc must face the pressure plate during installation. Insert a dedicated alignment tool or the transmission input shaft through the splined hole of the friction plate to ensure concentricity with the flywheel, enabling smooth installation of the transmission input shaft later.
Installing and Securing the Pressure Plate: Align the pressure plate with the locating pins on the flywheel and place it over the friction plate. Hand-tighten the pressure plate mounting bolts first, then gradually tighten them in a crisscross sequence with a torque wrench. For most Mitsubishi models (e.g., Pajero), the recommended tightening torque for pressure plate bolts is 25Nm to avoid pressure plate deformation due to uneven force. Ensure the alignment marks on the clutch cover, pressure plate, and diaphragm spring are aligned.
Assembling Release Components: Install the release bearing and release fork assembly, ensuring the release bearing moves smoothly without jamming. Apply lithium-based grease to the contact area between the release fork and release bearing to reduce wear. When installing the rubber dust cover, first insert the compression spring into the release bearing, then pre-compress the retaining ring to 18mm and lock it—control the locking torque of the release bearing at 15Nm.
Transmission Reset: Slowly lift the transmission with a lifting tool, align it with the engine interface, and ensure the input shaft is smoothly inserted into the splined hole of the friction plate. Tighten the transmission mounting bolts to the specified torque, then reconnect the clutch oil lines, shift cables, and other components. For hydraulic clutches, replenish hydraulic fluid and completely bleed air from the system.
Inspection and Adjustment: Reconnect the battery's negative terminal. Adjust the clutch pedal free travel to 15–25mm for Mitsubishi models—for the Pajero, this can be adjusted via the adjustment screw on the clutch pedal. Additionally, ensure the distance between the clutch release fork shaft drive arm and the fixed cable nut bracket is 195mm–205mm. After starting the vehicle, press the clutch pedal repeatedly to test the smoothness of clutch engagement and disengagement, as well as gear shifting. Make timely inspections and adjustments if any abnormalities occur.
The core precautions for installing the clutch friction plate of Mitsubishi vehicles revolve around five key aspects: "Compatibility, Cleanliness, Alignment, Torque, and Protection". Details are as follows:
Confirm the new friction plate is compatible with specific Mitsubishi models (e.g., Pajero, Outlander). Focus on verifying matching spline specifications and damping disc structure, and ensure the surface is free of oil contamination and cracks.
Tools must be calibrated in advance, especially torque wrenches, to avoid component damage caused by torque deviations. The dedicated alignment tool must match the vehicle's spline size.
The vehicle must be supported by safety stands—never rely solely on a jack. Secure both front and rear wheels with wheel chocks to prevent slipping during operation.
Strictly prohibit oil contamination on the contact surfaces of the friction plate, flywheel, and pressure plate. Keep hands dry; if oil is accidentally applied, thoroughly clean with a dedicated cleaning agent, otherwise starting slippage will occur.
Tighten pressure plate bolts in a "crisscross, step-by-step" manner. Strictly follow the vehicle's torque standard (25Nm for most Mitsubishi models, refer to the manual for exact values)—do not fully tighten at once or use insufficient torque.
Apply an appropriate amount of lithium-based grease to the contact area between the release bearing and release fork. Avoid over-application to prevent overflow and contamination of the friction plate. Ensure the rubber dust cover is properly installed, and the retaining ring's pre-compression dimension (18mm) and locking torque (15Nm) meet requirements.
Do not reverse the friction plate installation direction. The side with the damping disc must face the pressure plate, and an alignment tool must be used to ensure concentricity with the flywheel—otherwise, incomplete disengagement and gear shifting jams will occur.
When reinstalling the transmission, insert the input shaft smoothly into the friction plate splines. Avoid forced insertion to prevent spline wear or friction plate damage, and ensure the transmission fits tightly with the engine interface.
Fully bleed hydraulic clutches. After bleeding, replenish hydraulic fluid to the specified level—otherwise, a soft pedal and disengagement failure will occur.
Strictly calibrate the clutch pedal free travel (15-25mm) and the distance between the release fork shaft drive arm and the fixed cable nut bracket (195mm-205mm). Models like the Pajero require precise adjustment via dedicated adjustment screws.
