WHAT CAUSES MISALIGNMENT?

  • Missing or damaged dowel pins allowing the transmission to be bolted off centre.
  • Mislocated 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 with the engine running.
  • Deterioration of the clutch until non-release occurs.
  • Failed drive plate.
  • 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.

How to check for engine/transmission misalignment;

STEP 1
Mount indicator to flywheel and determine concentricity of bell housing bore to centre line of crank rotation, SPECIFICATION: 0.15mm max, T.I.R.

STEP 2
With indicator still mounted to flywheel ensure rear surface of housing is square. SPECIFICATION: 0.15mm max, T.I.R.

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.
