Different models of Mitsubishi vehicles may have differences in the installation details of the release bearing, but generally speaking, the installation method is as follows:Preparation Work: •  Tool Preparation: Prepare common tools such as wrenches, sockets, jacks, safety stands, etc. A special installation tool for the release bearing may also be needed.  •  Vehicle Protection: Park the vehicle on a flat and safe ground, pull the handbrake, and place wheel chocks to prevent the vehicle from moving. Use a jack to lift the vehicle steadily and support it firmly with safety stands to ensure that the vehicle will not shake or drop during the operation, then remove the tires to provide sufficient space for subsequent operations.  •  Disconnect the Power Supply: Disconnect the negative cable of the battery to prevent dangers such as short circuits during the installation process.Remove related components: ◦ Remove the transmission: First, remove the drive shaft and other components connected to the transmission, then loosen the fixing bolts of the transmission, and take the transmission off the engine and place it properly. ◦ Find and remove the old release bearing: The release bearing is usually located between the clutch disc and the clutch fork; carefully remove it from its installation position, paying attention not to damage the surrounding components.Cleaning and Inspection: ◦ Clean the installation position: Use a clean cloth or solvent to clean the installation position of the separator bearing, removing oil stains, impurities, rust, etc., to ensure that the mounting surface is clean and flat. ◦ Check related components: Check if the clutch pressure plate, clutch friction plates, release fork, and other components related to the separator bearing are worn or damaged, and replace or repair them if necessary. ◦ Check the new separator bearing: Inspect carefully for cracks, scratches, or other damage on the appearance of the new separator bearing, rotate the bearing to ensure it rotates smoothly without any sticking, and also check if the axial clearance of the bearing meets the requirements. Install the new separator bearing: ◦ Apply grease: Apply an appropriate amount of grease at the installation parts of the separator bearing, such as where the inner ring of the bearing contacts the journal and where the outer ring contacts the mounting seat hole, to ensure that the bearing can work properly and receive sufficient lubrication. ◦ Install the bearing: Correctly install the separator bearing onto the clutch release fork, ensuring that the bearing is in place and fits tightly with the release fork. Some models may require using a rocker on the removed clutch release fork shaft to press the separator bearing against the pressure plate, causing it to catch the spring and fix in the correct position. ◦ Adjust the gap: With the action of the return spring, the shoulder of the separator bearing should always be against the release fork and retract to its final position. Generally, a gap of about 3-4mm between the separator bearing and the end of the release lever (release finger) is required to ensure that the clutch can work properly.Reassemble other components: Install the transmission, drive shaft, and other components in reverse order of disassembly, ensuring that they are securely fastened and the connecting bolts are tightened to the specified torque. 6. Connect the negative battery cable: After installation is complete, check all components to ensure they are correctly installed and there are no omissions or loose parts. Once confirmed to be correct, reconnect the negative battery cable to the battery. 7. Test: Start the vehicle, step on the clutch pedal, and check if the release bearing is working properly, if the clutch is separating and engaging smoothly, and if there are any abnormal noises or other issues. If the release bearing is functioning normally, it indicates a successful installation; if there are problems, they should be promptly identified and resolved.

When installing Mitsubishi separator bearings, the following key points should be noted to ensure normal operation and extend the service life: Component inspection and matching • Model adaptation: Ensure that the new separator bearing is fully compatible with the vehicle model specifications, including size, structure, and tolerance requirements. Different Mitsubishi models may use different specifications of separator bearings due to varying displacements or years of production. Misfitting can lead to installation difficulties or early damage. • Quality inspection: The surface of the new separator bearing should be free from cracks, deformation, or rust, and it should be flexible and free from jamming when rotated. The axial clearance must meet the standard (usually not exceeding 0.3mm). If any abnormal noise or jamming is found, it must be replaced immediately.Installation Pre-Cleaning and Treatment: • Thorough cleaning: Use a lint-free cloth or special cleaning agent to clean the separator bearing mounting seat, contact parts of the separation fork, and related journal surfaces to remove oil stains, iron filings, and carbon buildup. This prevents impurities from entering the bearing and exacerbating wear. • Prohibition of striking: Separator bearings are precision components, and direct hammering during installation is strictly prohibited. They should be pushed in with a special tool or with even force to prevent damage to the internal balls or cage.Lubrication Specifications •  Selection of Grease: Use the special high-temperature grease recommended by the vehicle manufacturer (such as lithium-based grease). It is prohibited to use engine oil or ordinary butter to avoid lubrication failure caused by melting at high temperatures.  •  Application Position and Quantity: Apply a thin layer of grease only on the contact area between the inner ring of the release bearing and the journal, and the contact area between the outer ring and the release fork. The quantity should not be excessive to prevent excess grease from splashing and contaminating the clutch disc, which may cause slipping.

Installation Position and Clearance Adjustment:

• Installation Direction: Some release bearings have clear installation direction markings (such as "Facing the Pressure Plate"), which must be installed correctly according to the markings to avoid incorrect installation that leads to insufficient separation stroke or abnormal wear.

• Clearance Control: After installation, ensure that there is a free clearance of 3-4mm between the release bearing and the clutch release finger (end of the diaphragm spring). If the clearance is too small, it will result in incomplete clutch separation; if it is too large, it will cause an excessive pedal stroke. This can be achieved by adjusting the length of the release fork lever.

Reinstallation and Testing • Component Reinstallation Sequence: When reinstalling the transmission, it is necessary to slowly align it to avoid collision between the separator bearing and the pressure plate. The fixing bolts must be tightened symmetrically according to the specified torque (refer to the vehicle model manual, usually 25-35N・m) to prevent deformation of the transmission case that affects the bearing load. • Functional Testing: After starting the engine, repeatedly press the clutch pedal to feel if the travel is smooth and whether there is a 'squeaking' abnormal sound (sign of bearing wear). When shifting gears, there should be no jamming or tooth-grinding phenomenon. If any abnormalities are found, immediately stop the engine for inspection.

References：The content of my advice on the installation precautions for Mitsubishi separable bearings is a compilation based on information from multiple automotive repair platforms, and there is no specific single source. Among them, multiple articles on Autohome mention the need to pay attention to cleaning the installation location, correct installation direction, lubrication conditions, etc., when installing separable bearings. The content on Pacific Auto Network also emphasizes the importance of checking the bearing's movement flexibility, axial clearance, etc., before installation, and conducting test runs after installation. Additionally, relevant explanations from Shanghai Lingxiu Automation Technology Co., Ltd. include information on selecting the right bearings and following the manufacturer's guidelines. I have integrated and organized these key points from different sources to form the content of my previous answer.
