Oversized Secondary Pressure Regulator Valve Kit

Oversized Secondary Pressure Regulator Valve KitPart No. 113741-21K Also fits Mitsubishi F1CJA. Tooling: F-113741-TL21 VB-FIX 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 Note OE secondary pressure regulator valves have four spools. The smallest spool serves no function. Sonnax's oversized valve has only three function spools. Contents Valve O-Ring End Plug 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.
