Clutch and Flywheel
common clutch issues and causes
Sudden failure
Broken/loose clutch cable
Broken/loose linkage
Failed hydraulic master/slave cylinder
Leaking hydraulic line
Improper fit of throwout bearing with pressure plate
Disc contaminated with foreign material
Gradual failure
Stretched cable
Bent linkage
Failing master/slave cylinder
Low hydraulic fluid
Broken motor/transmission mount
Chattering
Burned or glazed friction surfaces
Oil on friction disk
Loose engine or transmission mounts
Worn splines on clutch disc hub
Warped pressure plate or flywheel
Worn pilot bearing
high petal effort
Links in need of lubrication
Binding cable
Binding petal pivot
Bad Throw-out bearing
Faulty slave cylinder
Fault pressure plate
clutch does not engage at all
Binding in linkage or cable due to corrosion
Bent linkage
Seized slave cylinder
Seized throw out bearing
Failed pressure plate diaphragm
Failed friction plate
Clutch Slips under load
Poor adjusted cable/linkage
Normal friction plate wear from use
Glazed friction surfaces from slipping
Worn flywheel friction surface
