JF017E RE0F10E Oversized Primary Pulley Reducing Valve K it
In Jatco/Nissan JF017E (RE0F10E) units, the primary pulley reducing valve controls and maintains oil pressure to the primary pulley actuator as influenced by the primary pulley solenoid. A worn bore or valve spool can cause loss of oil pressure control to the primary pulley actuator resulting in: chatter on acceleration, high or low pressure at the primary pulley actuator, pulley breakage and slippage in Forward and Reverse. Reconditioning the bore and installing Sonnax oversized primary pulley reducing valve kit 33510N-04K restores optimal oil pressure to the primary pulley actuator.
- Hardcoat anodized aluminum valve combats premature wear
- Oversized valve paired with OE spring matches OE pressure regulation algorithm
Symptoms
- Chatter on acceleration
- High or low primary pulley pressure
- Pulley breakage
- Slips in Forward & Reverse
Cause
Excess bore and valve train component wear allows critical oil volume/pressure to escape the circuit. Wear about the smaller valve spool can lead to excess oil pressure at the primary pulley actuator. Conversely, wear about the larger spools and end plug may cause insufficient oil pressure to the primary pulley actuator.
Correction
Restore proper hydraulic operation by refurbishing the bore and installing Sonnax oversized primary pulley reducing valve kit.
