The correct alignment of the driveline is critical for the operational life of your new Mantic Performance Clutch. Failure to have correct alignment will cause premature wear and / or driving release problems.
What causes misalignment?
- The most common causes of driveline misalignment are: Missing or damaged dowel pins allowing the transmission to be bolted off centre.
- Incorrectly located front bearing retainer.
- Foreign matter between the engine block and the transmission mounting faces.
- Missing or worn pilot bearing.
- Broken block flange.
What are the symptoms of misalignment?
- Pedal graunch (grating sound) with the engine running.
- Deterioration of the clutch until non-release occurs.
- Failed drive disc. (Generally broken between the hub and the facings)
- Red dust covering clutch and/or groove worn in the diaphragm by the release bearing.
How do I prevent misalignment?
Whenever you are replacing a clutch, inspect the old components. If misalignment is present you will need to find the cause.
- Inspect all dowels and dowel holes for condition.
- Inspect release bearing guide and replace if necessary.
- Clean all mating surfaces.
- Inspect block flange for damage.
REMEMBER - IF MISALIGNMENT IS PRESENT, FITTING A NEW CLUTCH KIT WILL NOT FIX THE CAUSE OF THE PROBLEM AND THE MISALIGNMENT WILL QUICKLY DESTROY THE NEW CLUTCH.
How to check for engine/transmission misalignment:
Does the clutch you have just removed show any of these signs of wear?
- Broken clutch disc.
- Loose pivot rings inside the cover assembly.
- Worn diaphragm fingers.
- Release bearing guide worn on one side.
- Red dust covering the clutch assembly.
If it does, the clutch has probably failed due to driveline misalignment. Fitting a new clutch without rectifying any misalignment will lead to possible premature failure of the new clutch.
