The installation of the clutch friction plate for Mitsubishi vehicles must follow specific directional and torque requirements, especially for models like the Pajero which have clear assembly specifications. The overall installation process is synchronized with the assembly of the clutch three-piece set. Detailed steps are as follows:
Park the vehicle on a flat surface, engage the handbrake, and secure the wheels with wheel chocks. Disconnect the negative battery terminal to avoid electrical accidents. Lift the vehicle with a jack and firmly support it with safety stands. Then remove the drive shaft and gearbox to fully expose the clutch assembly.
After removing the clutch pressure plate and old friction plate (driven plate), clean oil stains and impurities from the surfaces of the flywheel and pressure plate with a clean cloth. Meanwhile, inspect the flywheel and pressure plate for wear and cracks, and check if the crankshaft pilot bearing is intact. Replace any damaged components promptly. Additionally, prepare new parts such as the friction plate and pressure plate, as well as tools including wrenches, alignment pins, and grease.
Apply grease: Coat the release bearing, release fork pivot points, and all supporting surfaces with basic grease to reduce frictional wear during component operation.
Position the friction plate: Place the new friction plate between the flywheel and pressure plate, ensuring the side with the damper disc faces the pressure plate. Use an alignment pin or the transmission input shaft for centering to ensure the driven plate (friction plate) is concentric with the pressure plate, facilitating subsequent input shaft installation.
Install the pressure plate assembly: Align the assembly marks on the clutch cover, pressure plate, and diaphragm spring for precise positioning. Fit the pressure plate tightly against the flywheel and secure it with bolts. Tighten the bolts diagonally one by one—for most Mitsubishi models, the tightening torque here is 25Nm to prevent uneven pressure on the pressure plate.
Install the release bearing: Insert the compression spring into the release bearing, pre-compress the retaining ring to 18mm, then lock it in place. Control the locking torque of the release bearing at 15Nm. Subsequently, install the release fork, ensuring both ends of the release fork shaft are concentric, and the distance between the release fork shaft drive arm and the fixed cable nut bracket is between 195mm and 205mm.
Reinstall surrounding components: Reattach the gearbox, drive shaft, and other parts in the reverse order of removal. Ensure all connectors are securely fastened during installation to prevent loosening during transmission.
Adjust pedal travel: Use the clutch pedal adjustment screw to set the free pedal travel to 15mm - 25mm, ensuring the sensitivity of clutch engagement and disengagement.
Startup test: Reconnect the negative battery terminal. After starting the vehicle, test the smoothness of gear shifting and check for jitter, abnormal noise, or other issues during clutch engagement and disengagement. If gear shifting is stiff or abnormal noises occur, inspect the installation direction of the friction plate, the torque of the pressure plate bolts, or the condition of the release bearing, and make timely adjustments to troubleshoot the problem.
The core precautions for installing the clutch friction plate of Mitsubishi vehicles focus on direction, positioning, torque, and condition inspection, which directly affect safety and service life:
Installation direction must never be wrongThe side of the friction plate with a damper disc (or spring damping structure) must face the pressure plate, and the side with the short end of the spline hub must face the flywheel. Reversed installation will cause the clutch to fail to disengage and gear shifting to malfunction.Some Mitsubishi models (such as Pajero, ASX) have a "face pressure plate" mark on the edge of the friction plate. Be sure to check it before installation to avoid confusion.
Central positioning is criticalA dedicated alignment tool or the original transmission input shaft must be used to accurately position the friction plate at the center of the flywheel, ensuring concentricity with the pressure plate and flywheel.If the positioning is incorrect, it will prevent the transmission input shaft from being installed, or cause clutch engagement jitter and accelerated wear after installation.
Bolt tightening must strictly follow specificationsThe pressure plate fixing bolts must be tightened evenly in a diagonal pattern. Never fully tighten one bolt at a time to avoid pressure plate deformation.Strictly follow torque standards: For most Mitsubishi models, the pressure plate bolt torque is 25Nm, and the release bearing locking torque is 15Nm. Never tighten arbitrarily by feel.
Cleaning and lubrication are essentialThe friction contact surfaces of the flywheel and pressure plate must be thoroughly cleaned, free of oil stains and iron filings; otherwise, clutch slippage and abnormal noise will occur.Apply only a small amount of special grease to rotating parts such as the release bearing and release fork pivot points. Never apply grease to the friction surface of the friction plate or the working surfaces of the flywheel and pressure plate.
Necessary condition checks before installationCheck the fit clearance between the spline hub of the new friction plate and the transmission input shaft; it should slide smoothly without jamming.Recheck the flywheel end face runout (should be ≤0.2mm), whether the pressure plate diaphragm spring is deformed, and whether the crankshaft pilot bearing rotates smoothly. Replace any faulty components simultaneously.
Commissioning and testing after installationThe pedal free travel must be adjusted to 15mm-25mm. Excessive travel will cause incomplete disengagement, while insufficient travel will cause clutch half-engagement wear.After starting, first run in neutral idle to check for abnormal noise; then test the smoothness of gear shifting in all gears and check for jitter during 起步. If abnormalities occur, disassemble and inspect immediately.

The core information about the installation methods and precautions for Mitsubishi vehicle clutch friction plates you previously reviewed is integrated from Mitsubishi's vehicle maintenance specifications and professional content on auto repair platforms. Specific reference sources are as follows:
Key details about Pajero clutch assembly here—such as the friction plate with a damper disc facing the pressure plate, diagonal tightening of pressure plate bolts with a torque of 25Nm, release bearing locking torque of 15Nm, installation distance of 195mm - 205mm between the release fork shaft drive arm and the fixed cable nut bracket, and clutch pedal free travel of 15mm - 25mm—fully match the core data in the response, making it one of the important information sources.
Specifications such as the requirement to use a dedicated alignment tool for positioning the friction plate during installation, the need to apply Mitsubishi genuine grease to specific parts, and the alignment requirements for component assembly are consistent with the core points of clutch assembly in Mitsubishi's official technical documents, complying with the exclusive maintenance standards for Mitsubishi models.
General installation processes for clutch friction plates published on platforms like PCauto and Auto Repair Treasure—including pre-installation vehicle fixing and component cleaning, reinstalling the gearbox and other surrounding parts in the reverse order of removal, and testing gear shifting and clutch operation after installation—serve as supplementary content to improve the completeness of the overall operation process.
