The installation method for Scania clutch friction plates is as follows: • Preparation work: Park the vehicle on a flat and safe ground, pull up the handbrake and secure the wheels to prevent the vehicle from moving. Disconnect the vehicle's power supply to avoid accidents during the installation process. Prepare the required tools, such as wrenches, sockets, torque wrenches, etc. At the same time, check whether the specifications and model of the new clutch friction plate match the vehicle and whether there is any damage.Remove related components: First, remove components connected to the transmission such as the drive shaft, then gradually unscrew the fixing bolts of the clutch cover. When removing the bolts, to prevent the clutch cover from popping out suddenly and causing injury, it is recommended to loosen each bolt by only one turn at a time until the spring tension is completely released, and then remove all the bolts. Next, take off the clutch cover, the clutch friction disc assembly, as well as components like the release bearing and release fork, and mark them properly for correct reinstallation later.Cleaning and Inspection: Use a clean rag or a dedicated cleaning agent to thoroughly clean the surfaces of the flywheel and pressure plate, removing oil stains, rust, and impurities, ensuring that the mounting surfaces are flat and smooth. At the same time, carefully inspect the flywheel and pressure plate for wear, cracks, deformation, and other issues; if any abnormalities are found, they need to be replaced in a timely manner. In addition, check whether the splines of the transmission input shaft are intact and free from wear or damage.Installing a new clutch friction disc: •  Install the pilot bearing (if required): Apply an appropriate amount of grease into the pilot bearing hole of the flywheel, then gently tap the pilot bearing into place to ensure it is securely installed and rotates smoothly.  •  Determine the installation direction: The installation direction of the clutch friction disc may vary for different vehicle models. Generally, the side with a flange or special marking usually faces the transmission; some models require the side of the driven disc with the protruding damping spring to face the pressure plate. For details, refer to the vehicle's repair manual or the markings on the friction disc. Place the friction disc correctly on the flywheel and align the splined hole with the splines of the transmission input shaft.  •  Install the pressure plate: Align the pressure plate with the assembly marks on the flywheel for installation, then initially secure it with bolts without fully tightening them.Secure and adjust: Use a torque wrench to gradually and evenly tighten the fixing bolts of the pressure plate in diagonal order according to the specified torque value, ensuring that the pressure plate is securely installed and evenly stressed. For clutches equipped with diaphragm springs, it is necessary to check whether the height of the diaphragm spring top meets the requirements. The height difference between each spring's top should generally not exceed 0.5 millimeters. If there is a deviation, use a special tool for adjustment.Install the release bearing and release fork assembly: Correctly install the release bearing onto the release fork, then install the release fork assembly in the corresponding position. Ensure that the release bearing makes good contact with the release fingers of the pressure plate, moves smoothly, and apply an appropriate amount of lithium-based grease to the relevant connection points.  •  Reinstall the transmission: Carefully move the transmission back to its original position, reconnect it to the engine, and tighten the connecting bolts to the specified torque. During the installation of the transmission, be careful to avoid colliding with the already installed clutch components.Connect other components: Reinstall the transmission shaft and other previously removed parts in the reverse order of disassembly, ensuring that all connections are secure. 9. Adjust the clutch pedal: Check and adjust the free travel and height of the clutch pedal to meet the technical requirements of the vehicle. Generally, the free travel of the clutch pedal on Scania vehicles should be maintained between 20-25mm.Inspection and Testing: Check the installation of clutch-related components again to ensure that all bolts are tightened and each part is securely connected. Start the vehicle, press down on the clutch pedal, check if the clutch's separation and engagement are smooth, there are no abnormal noises, slippage, etc., and also check if the gear shifting is smooth. If there are any issues, they should be promptly identified and resolved.

When installing Scania clutch friction plates, there are a few precautions to take:

• Component Inspection and Cleaning:

◦ Check the quality of the friction plate: Before installation, carefully inspect the appearance of the new friction plate to ensure it is free from cracks, wear, deformation, etc., and confirm that its specifications and model match the vehicle exactly.

Installation Process Notes:Ensure the correct installation direction of the friction plate: The installation direction of the clutch friction plates may vary between different vehicle models. Generally, the side with a flange or special marking should face the transmission; some models require that the side of the driven disc with the vibration damper spring protruding should face the pressure plate. During installation, refer to the vehicle maintenance manual or the markings on the friction plate to correctly position the friction plate.Inspection and Debugging After Installation: •  Checking Component Installation: After the installation is completed, it is necessary to recheck whether the clutch-related components are installed correctly, whether all bolts are tightened, and whether the connections of each component are reliable.  •  Adjusting the Clutch Pedal: It is necessary to check and adjust the free travel and height of the clutch pedal to meet the vehicle technical requirements. Generally, the free travel of the clutch pedal for Scania vehicles should be maintained between 20-25mm.
