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.
