Symptoms:

  • Push belt slippage & pulley fracture
  • RPM surge or chatter on acceleration

Cause:

Loss of pressure control to the secondary pulley. Low pressure to the pulley causes chatter, push belt slip, surface fretting and metal contamination. With low pressure, pully diameter will not change and ratio remains the same.

Correction:

Refurbish the bore using the Sonnax tool kit and install the Sonnax valve and end plug.
