Areas of Importance
1. Clutch Rigid Pipe Installation
Before installing, check to make sure that the rigid pipe flare contact area is in good condition, the pipeline is
clean, and that there is no foreign materials.
2. Clutch Hose Installation
Check the surface of the clutch hose to make sure that there is no scuffing and that the pipeline is clean.
3. Coat grease on the U-joint of the pedal and the master cylinder.
4. Strictly adhere to the set torque guidelines when tightening the pipe fittings.
Rigid pipe and the master cylinder: M10 16±2 N·m
Clutch rigid pipe and hose: M10 16±2 N·m
5. While the clutch system is undergoing the exhausting process, make sure that all the air bubbles in
the pipeline are cleared out. Then check the brake fluid level in the reservoir, it should be between
MIN and MAX.
Troubleshooting
The numbers in the table represent the order of the possible malfunction causes, so be sure to check each part in
turn. If necessary, replace the part.
SymptomsPossible Causes
Clutch vibration1. Engine mounting bracket (loose)
2. Clutch plate (axial runout is too much)
3. Clutch plate (oil build-up)
4. Clutch plate (polished)
5. Clutch plate (hardened)
6. Diaphragm spring (damaged)
Clutch pedal is spongy1. Clutch pipeline (air entering)
2. Clutch master cylinder cup (damaged)
3. Clutch slave cylinder cup (damaged)
