The clutch driven disk assembly (1000579175) and clutch cover assembly (1000579174) are a matched set designed for Weichai WP4.1 series diesel engines, with a diameter of 380mm .

1. Installation Location
Both components are installed between the engine flywheel and the transmission input shaft. The clutch cover assembly is bolted to the flywheel, and the driven disk is sandwiched between the cover and the flywheel surface. The driven disk fits over the transmission input shaft splines.

2. Function
The clutch cover assembly applies clamping force through its diaphragm spring to press the driven disk against the flywheel, transmitting engine torque to the transmission . The driven disk features a torsion damper hub to absorb driveline vibrations and a wear-resistant friction lining for smooth engagement .

3. Maintenance and Service
Both assemblies are wear items requiring periodic replacement. A new clutch set ensures consistent clamping force, optimal heat dissipation, and improved anti-slip resistance . The clutch cover assembly is also designed for high-speed stability with reliable diaphragm spring performance . When replacing, both the driven disk and cover should be replaced as a set with new release bearings.

4. Important Notes
Verify the part numbers (1000579175 and 1000579174) match the original components. These are service parts for WP4.1 applications only . Ensure the flywheel and pressure plate surfaces are clean before installation and torque all bolts to manufacturer specifications.
