SERVICE INSTRUCTION:

1. NOTE: Removal of the supercharger drive belt and running of the engine to verify the clattering noise is emanating from the supercharger assembly must be done prior to the fitting of a new supercharger assembly.

Remove the supercharger drive belt and rotate the supercharger pulley by hand:

• If there is a ‘clunk’ / ‘knock’ noise from the supercharger or significant free play when turning the pulley before the rotors start to turn and not one of the symptoms below, install a supercharger spring isolator kit (see TOPIx Workshop Manual, section 303-12C).
• If any of the following symptoms are present, replace the supercharger assembly. To be performed as a separate claim.
  • The pulley does not rotate freely (‘sticks’, difficult to move, roughness felt in bearing); and/or
  • The blades / rotors are damaged;
  • and/or Customer reported excessive ‘whine’ noise.
