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.

• Hardcoat anodized aluminum valve combats premature wear
• Oversized valve paired with OE spring matches OE pressure regulation function
