The installation steps and precautions for Sachs clutch friction plates are as follows: Preparation before installation •  Cleaning components: Thoroughly clean the surfaces of the pressure plate and flywheel to remove all oil, impurities, and dust, preventing clutch slippage.  •  Inspecting parts: Check the fit between the splines of the clutch driven plate hub and the input shaft splines; they should move freely without jamming or obvious looseness. At the same time, check whether the new clutch friction plate has defects such as oil stains or cracks. For clutches with newly riveted friction plates, check whether the driven plate and friction plate are too thick.  •  Soaking the friction plate: New clutch plates should be soaked in transmission oil and allowed to absorb sufficient oil before assembly.Installation Steps Make assembly marks: Make assembly marks on the clutch cover assembly and flywheel assembly to ensure correct alignment during installation. Remove related components: Gradually loosen the fixing bolts of the clutch cover, loosening each bolt one turn at a time until the spring tension is completely released. Then remove the fixing bolts, pull down the clutch cover, clutch friction disc assembly, release bearing, and release fork. Then remove the release fork and release bearing assembly from the first shaft of the transmission. Lubricate the pilot bearing: Add lubricating oil to the flywheel pilot bearing to ensure effective lubrication.Install the release bearing and release fork assembly: Mount the release bearing and release fork assembly onto the first shaft of the transmission, and check if the release bearing moves smoothly.  •  Install the friction plate: Apply lubricating oil to the splines of the clutch disc, insert the guide shaft and clutch friction plate into the flywheel assembly. Pay attention to the installation direction: the side of the driven disc with the protruding damping spring should face the pressure plate, the side with the boss should face the transmission, and the flat side should face the flywheel.  •  Install the clutch cover: Locate the positioning pins on the flywheel, fix the clutch cover onto the positioning pins, hand-tighten the fixing screws, gently shake it, and then pull out the guide shaft.  •  Tighten the bolts: Uniformly tighten the fixing bolts of the clutch cover according to the specified torque. Never apply uneven force or insufficient torque.Post-installation Inspection •  Check Connection Status: Inspect whether the connection between the clutch friction plate, flywheel, and pressure plate is tight and if there is any looseness.  •  Test the Clutch Pedal: Start the engine, check if the operation of the clutch pedal is smooth, and if there are any jamming, abnormal noises, etc. Perform a gear shift test to check if the gear shifting process is smooth and if the power transmission is normal.  •  Adjust Pedal Free Travel: Check the free travel of the clutch pedal, which should always be between 20-25mm. If it does not meet the requirements, adjustment is needed.

The following are the precautions for installing the Sachs clutch friction plate:Preparation before installation •  Cleaning and inspection: Thoroughly clean the surfaces of the pressure plate and flywheel to remove oil, impurities, and dust, preventing clutch slippage. At the same time, check if the friction plate has cracks, severe wear, or other issues; if so, it needs to be replaced in a timely manner.  •  Inspection of part fit: Check the fit between the splines of the clutch driven plate hub and the input shaft splines; they should move freely without jamming or obvious looseness.  •  Handling of the friction plate: New clutch plates should be soaked in transmission oil and fully saturated with oil before assembly.Installation ProcessCorrect Installation Orientation: The side of the friction plate with the boss should face the gearbox, and the flat side without the boss should face the flywheel. Ensure the installation orientation is correct; otherwise, it will affect the clutch performance.Use of Special Tools: Special tools such as a guide shaft should be used during installation to ensure the center of the clutch plate is accurately aligned with the centers of the flywheel and pressure plate, avoiding deformation of the clutch cover or improper installation.Uniform Force Application: When installing the friction plate, appropriate tools are needed to press it evenly into the flywheel to prevent deformation of the friction plate due to uneven pressure. Use a torque wrench to alternately tighten the fixing bolts or nuts diagonally according to the specified torque, ensuring secure installation without deformation or damage to the friction plate caused by excessive torque.Lubrication Treatment: Appropriately lubricate the splines of the driven disc and the splines of the first shaft of the gearbox with temperature-resistant and pressure-resistant grease, but be careful not to use an excessive amount to prevent slipping.Post-installation Inspection •  Check the Clearance: After the installation is completed, the clearance between the friction plate and the flywheel should be checked to ensure it is within the normal range. Too small a clearance will cause the friction plate to wear out too quickly, while too large a clearance may cause slipping.  •  Test Run: Start the vehicle, check if the operation of the clutch pedal is smooth, and see if there are any jamming, abnormal noises, etc. Conduct a gear shifting test to check if the gear shifting process is smooth and if the power transmission is normal.
