The installation steps for the clutch friction disc of a modern car are as follows: •  Preparation Work: Park the vehicle in a safe and flat place, pull up the handbrake, and prepare the required tools as well as new components such as the clutch friction disc, pressure plate, and release bearing.  •  Removal of Related Components: Open the engine hood and remove the engine to expose the clutch assembly. Then remove the clutch cover, unscrew the screws fixing the flywheel, take off the flywheel, and you can see the old clutch friction disc.Removing the old clutch friction disc: Make assembly marks on the clutch cover assembly and flywheel assembly, then loosen the fixing bolts 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 in sequence, and finally remove the release fork and release bearing assembly from the first shaft of the transmission.  •  Cleaning and inspection: Wipe the surfaces of the flywheel and pressure plate with a clean cloth to remove oil, dust and impurities. Check the wear condition of components such as the flywheel, pressure plate and release bearing. If there is severe wear or damage, they should be replaced in a timely manner.Install the pilot bearing: Apply lubricating oil to the pilot bearing on the flywheel, then install the pilot bearing into the corresponding hole of the flywheel.  •  Install the release bearing and release fork assembly: Install the release bearing and release fork assembly onto the first shaft of the transmission, ensuring that the release bearing moves smoothly.  •  Install the new clutch friction disc: Place the new clutch friction disc on the transmission, align the splines in the middle with the drive shaft, pay attention to the direction of the friction disc. The side with the boss faces the transmission, or according to the marks on the friction disc, make the side marked "flywheel side" face the flywheel.Inspection and Testing: Check if all components are securely installed and connections are correct. Start the vehicle, check if the stroke of the clutch pedal is normal, if the clutch disengages and engages smoothly, and if there are any abnormal noises or vibrations.

When installing the clutch friction disc of a modern car, the following precautions must be focused on to ensure the assembly quality and the normal operation of the clutch system: 1. Precautions for preparation before installation Component selection and inspection: It is necessary to select original or qualified aftermarket friction discs that match the vehicle model to avoid failures caused by improper dimensions; for new friction discs, check whether the surface has oil stains or damage, and whether the spline hole is smooth without burrs. If there is anti-rust oil on the surface, wipe it clean with a clean cloth (do not use highly corrosive solvents such as gasoline). At the same time, it is recommended to check and replace the pressure plate, release bearing (even if not completely damaged, old components may not match well with the new friction disc), and the pilot bearing of the flywheel synchronously.Tool and Environment Preparation: Prepare tools such as a torque wrench (critical), socket, guide shaft (for auxiliary positioning of the friction plate), cleaning cloth, and grease (special high-temperature grease); the operating environment must be dry and clean to prevent dust and impurities from entering the clutch system, which may affect the engagement accuracy.  •  Safety Protection: The vehicle needs to be lifted with a jack and fixed on a bracket to ensure the stability of the vehicle body; wear gloves during operation to prevent hands from being scratched by the edges of components, and at the same time avoid oil stains from contaminating the working surface of the friction plate.Key Precautions for Disassembly and Cleaning •  Marking Alignment: When disassembling the clutch cover and flywheel, be sure to make assembly marks with a marker pen (such as the positions of corresponding bolt holes) to ensure accurate positioning during installation and avoid uneven force on the pressure plate.  •  Cleaning the Flywheel and Pressure Plate: Thoroughly wipe the working surface of the flywheel and the surface of the pressure plate with a cleaning cloth to remove oil stains, carbon deposits, and wear debris; if the flywheel surface has severe scratches, warpage (the gap checked with a straightedge exceeds 0.2mm), or excessive wear, it needs to be ground or directly replaced. Otherwise, it will cause uneven force on the friction plate, slipping, or jitter.  •  Inspection of the Release Mechanism: Check whether the release fork and release bearing seat are deformed or worn. The release bearing must rotate smoothly without jamming or abnormal noise. Before installation, a small amount of high-temperature grease can be applied to the outer ring of the bearing to extend its service life.
