TROUBLE DIAGNOSIS
Trouble symptom Cause Treatment method Slip of clutch •Free travel (free play) of clutch pedal is wrong. •Abrasion or oil stain for clutch friction disk. •Distortion for friction disk 、 pressure plate or flywheel surface. •Diaphragm springs become weaker. Adjust free travel Change friction disk Change frication disk, pressure plate or flywheel Change clutch pressure plate Uncompleted segregation of clutch •Free travel of clutch pedal is wrong. •Diaphragm springs become weaker or abrasion for stabber fingertip. •Rust for input axle spline. •Mutilation or abrasion for input axle spline of transmission. •Excessive nodding action for clutch friction disk assembly. •Abrasion or oil stain for clutch friction disk. Adjust free travel Change pressure plate
Lubricate Change the input shaft
Change friction disk
Change friction disk Vibration of clutch •Brighten of clutch friction disk (to become glassiness). •Oil stain for clutch friction disk. •Bad skid of segregation bearing on the bearing sleeve of transmission. •Shimmy of clutch friction disk assembly or bad connection of friction disk. •Vibration reduction torsion springs of clutch friction disk assembly become weaker. •Loose of rivet of clutch friction disk. •Distortion of pressure plate or flywheel surface.
•Loose of the binding bolt of flywheel or loose of binding bolt of pressure plate assembly. Repair or change friction disk Change friction disk Lubricate
