Symptoms:

Push belt slippage & pulley fracture
Chatter on acceleration
RPM surge on acceleration

Cause:

Excess wear of the secondary pressure regulator valve train and bore will result in uncontrolled secondary pulley pressure deviations causing timing issues and slippage between secondary and primary pulleys.

Correction:

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

In Jatco/Nissan JF011E (RE0F10A) units, the secondary pressure regulator valve supplies and maintains oil pressure in the secondary pulley circuit as commanded by the secondary pressure control valve. A worn bore or valve spool can cause loss of oil pressure control in the secondary pulley circuit. Symptoms that may indicate degraded secondary pulley pressure control are: push-belt slippage and pulley fracture, chatter and/or RPM surge upon acceleration.

Reconditioning the bore and installing Sonnax oversized secondary pressure regulator valve kit 113741-21K can restore optimal oil pressure management in the secondary pulley circuit.

Oversized valve paired with OE spring matches OE pressure regulation function

Note

OE secondary pressure regulator valves have four spools. The smallest spool serves no function. Sonnax's oversized valve has only three function spools.
