CONDITION SUMMARY:
Situation:
A ‘clattering’ noise may be heard from the engine. Upon further investigation, including removing the
supercharger drive belt and running the engine to confirm the noise is no longer present, the noise may be found
to be coming from the supercharger assembly.

Cause: This may be caused by the following conditions:
• The torsional isolator spring may fail due to lack of adequate input shaft pilot support, leading to
overhang and increased stresses in the torsion spring and causing excessive backlash in the
supercharger drive and no torsional damping.
• Bearing contamination.

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.
Action: In the event of a customer concern of the above, refer to the Repair Procedure outlined below.
