LU-16 < SERVICE INFORMATION > [VQ35DE] OIL PUMP • Measure the clearance with feeler gauge. tion “1”) - Tip clearance between oil pump inner rotor and oil pump outer rotor (position “2”) • Measure the clearance with feeler gauge and straightedge. (position “3”) - Side clearance between oil pump outer rotor and oil pump body (position “4”) • Calculate the clearance between oil pump inner rotor and oil pump body as follows: OIL PUMP BODY INNER DIAMETER - Measure the inner diameter of oil pump body with inside microme- ter. (Position “5”) OIL PUMP INNER ROTOR OUTER DIAMETER - Measure the outer diameter of protruded portion of oil pump inner rotor with micrometer. (Position “6”) OIL PUMP INNER ROTOR TO OIL PUMP BODY CLEARANCE - (Clearance) = (Oil pump body inner diameter) – (Oil pump inner rotor outer diameter) • If measured/calculated values are out of the standard, replace oil pump assembly. Regulator Valve Clearance (Clearance) = (Valve hole diameter) – (Regulator valve outer diame- • If the calculated value is out of the standard, replace oil pump assembly. CAUTION: • Coat regulator valve with engine oil. weight.
