Driveline Alignment

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.
