Disc Contamination
Initiator:
Slipping Clutch/Shudder or Judder
Cause:
1. Rear main engine seal failure/fatigue
2. Front gearbox seal failure/fatigue
3. Excessive lubrication on the clutch disc splines/gearbox nose cone/release bearing
Effect:
Oil or Grease contamination on the clutch disc linings
Action:
1. Replace the clutch disc/kit
2. Inspect the rear main seal for leaking – replace if necessary
3. Inspect front gearbox seal – replace if necessary
4. Inspect any other engine oil leaks which could compromise the gearbox bellhousing (i.e sump gasket, rocker cover etc)
5. Remove any excessive lubrication from the clutch components once they have been checked for compatibility.
