Clutch makes a noise

The following easy to use charts are provided to enable clutch problems to be easily identified and make diagnosis simpler.


Problem Cause Remedy
Bearing running eccentrically to diaphragm fingers Bearing not centreing Renew bearing
No drive Renew pressure plate or driven plate
Incorrect driven plate Torsion damper incorrect for vehicles application Fit correct driven plate
Torsion damper broken Incorrect damper Fit correct driven plate
Release bearing defective Not rotating smoothly Renew bearing
Spigot (pilot) bearing defective Bearing seized Renew bearing
Damaged damper spring breakout Incorrect driving habits
Wrong gear selection
Renew driven plate

1. Worn diaphragm spring fingers
Cause 
• Release bearing seized
• Faulty release system
• Incorrectly adjusted release system

2. Damaged idle damper
Cause 
• Incorrect fitting
• Incorrect driven plate

3. Retainer spring damaged
Cause 
• Incorrect fitting
-> Incorrect diaphragm spring in clutch assembly


4. Spring window damaged
Cause 
• Incorrect driven practice
-> Driving the vehicle in too high a gear at low revs
• Incorrect clutch driven plate


5. Torsion damper spring broken out
Cause 
• Facings contaminated with oil
• Out of tune engine
• Faulty release mechanism
-> Chatter vibration damages the torsion damper


6. Torsion damper stop rivet worn
Cause 
• Incorrect driven practice
-> Driving the vehicle in too high a gear at low revs
• Incorrect clutch driven plate


7. Spline damaged on one side forming a taper, torsion damper damaged
Cause 
• Faulty spigot (pilot)
• Misalignment condition between engine and gearbox


8. Worn splines
Cause 
• Worn or missing spigot (pilot) bearing
• Misalignment condition between engine and gearbox
• Damaged gearbox input shaft
• Induced torsional vibration


9. Casing and ball bearing damage
Cause 
• Overheating of release bearing due to incorrect clearance causing loss of grease and break up of bearing


10. Release bearing worn
Cause 
• Incorrect adjustment of release arm
• Insufficient bearing preload
(specification 80 – 100 N)


11. Gearbox snout worn
Cause
• Incorrect grade of grease or no grease used
• Damaged release bearing


12. Running surface on release bearing worn
Cause 
• Release system worn
• Incorrect bearing preload
(specification 80 – 100 N)


13. Worn release lever
Cause 
• None or incorrect grease used


14. Release bearing tappet points worn
Cause
• Tappet points not lubricated
• Release system worn


15. Push rod wear mark off centre
Cause 
• Damaged release system
-> Bearing worn
-> Guide bush worn


16. Damaged bearing lugs
Cause 
• Damaged release system


17. Bearing fouling clutch cover
Cause 
• Clutch cover and release bearing mismatch


18. Torsion damper broken
Cause
• Incorrect driven practice
-> Driving the vehicle in too high a gear at low revs
-> Grease/oil contaminated facing


19. Hub assembly broken
Cause
• Incorrect fitting
-> Driven plate fitted the wrong way round
