Clutch Slippage Phenomenon: Insufficient power during start-up or heavy load, weak acceleration, and in severe cases, smoke and a burning smell from the friction plates.

Clutch slippage
Phenomenon: Insufficient power when starting or under heavy load, weak acceleration, and in severe cases, smoke and burning smell from the friction plates.
Cause:
The pedal free travel is too small, resulting in insufficient clamping force.
The friction plate surface is oily, burned, hardened, or the rivets are exposed.
The pressure plate spring is weakened or broken.
Incomplete separation
Phenomenon: Difficulty shifting gears, noticeable impact sound from the gearbox.
Cause:
The pedal free travel is too large, and the pressure plate travel is insufficient.
Inconsistent separation lever height, uneven warping of the driven and driving plates.
Abnormal noise
Phenomenon: Abnormal noise when the clutch engages or disengages.
Cause:
Release bearing is lacking oil or damaged.
The rivets of the driven disc hub are loose, and the splines are worn.
Shaking at start-up
Phenomenon: The vehicle body shakes when starting after engaging the gear.
Cause:
Inconsistent separation lever height, uneven pressure plate spring force.
Warping and deformation of the driven and driving plates, wear of the splines on the driven disc hub.
