Symptoms:

  • Push belt slippage
  • Pulley breakage
  • RPM surge
  • Chatter on acceleration

Cause:

Excessive bore/valve wear allows circuit cross-leakage that exhausts critical oil pressure and volume. Wear at the inboard valve spool may cause high line pressure. Wear at the other spools will typically lead to low line pressure.

Correction:

Restore proper hydraulic control by reconditioning the bore and installing the Sonnax oversized secondary pulley/pressure regulator valve kit.
