The installation steps and precautions for the smart clutch kit are as follows: Installation Steps •  Preparation: Disconnect the negative pole of the battery to prevent dangers caused by misoperation. Prepare tools such as a jack, support frame, torque wrench, and screwdriver, and check whether the clutch kit is intact.  •  Removal of Related Components: Lift and secure the vehicle, remove the connection part between the drive shaft and the gearbox, then 卸下 the old clutch assembly, and record the removal sequence for subsequent installation.  •  Cleaning the Mounting Surface: Clean the surface of the flywheel and the input shaft of the gearbox to ensure there is no oil stain or impurity.Install the new clutch disc: Place the new clutch disc smoothly on the flywheel in the correct orientation. Generally, the side with the damping plate should face the pressure plate.  •  Install the pressure plate: Mount the pressure plate back to its original position. Use a guide locator or the transmission input shaft for centering to ensure the driven disc is concentric with the pressure plate. Then, tighten the pressure plate bolts one by one diagonally to the specified torque.  •  Install the release bearing: Ensure the release bearing makes good contact with the pressure plate and operates without jamming.  •  Install the actuator motor: Gently push the actuator motor until it touches the fork, make a mark, then push it three scales past the mark with force, and tighten the three fixing screws.Reconnect the drive shaft: Check if the connection is secure.  •  Add transmission oil: Since the transmission needs to be removed during the installation process, a large amount of gear oil will leak out, so transmission oil should be added after the installation is completed.  •  Restore the battery connection: Reconnect the negative pole of the battery.  •  Learning and testing: Press the brake, turn on the ignition (do not start the engine), and you will hear the actuator motor automatically relearn the new stroke until the N gear is displayed. Turn off the key again, turn on the power again, start the car, try to shift gears, and check if it is normal.

NotesTool Usage: Special tools should be used during the installation process to avoid damaging parts.Component Cleaning: Before installation, ensure that the clutch kit and related installation parts are clean to prevent dust or debris from entering the inside of the transmission.Correct Orientation: The installation direction of the clutch disc must not be wrong. The side with the boss faces the transmission, and the flat side faces the flywheel.Bolt Tightening Torque: The pressure plate bolts should be tightened to the specified torque. Unless otherwise specified, the general tightening torque is 25Nm.Adjustment of the actuating head motor: The adjustment of the actuating head motor is very crucial. Improper adjustment may cause damage to the motor. It is recommended to follow the original factory manual for operation and use a decoder to perform standard basic settings and matching.
