The friction surface is subjected to high-frequency quenching treatment, and the surface roughness is controlled within Ra3.2 to ensure uniform contact.
Some models use chromium molybdenum alloy cast iron to improve high-temperature stability.

The clutch pressure plate needs to be checked regularly
Check the surface of the pressure plate for wear, scratches, fractures, or warping deformation.
Measure the thickness of the friction plate, if it is lower than the minimum value calibrated by the original factory, it needs to be replaced.
