Remove oil pump cover. INSPECTION AFTER DISASSEMBLY Clearance of Oil Pump Parts • Measure radial clearance using a suitable tool. • Measure side clearance using suitable tools. • Calculate the clearance between inner rotor and oil pump body as follows. 1. Measure the inner diameter of oil pump body to brazed portion (position 5) using suitable tool. 2. Measure the outer diameter of protruded portion of inner rotor (position 6) using suitable tool. 3. Calculate the clearance using the following formula. • (Clearance) = (Inner diameter of oil pump body) - (Outer diameter of inner rotor) Regulator Valve Clearance Body to outer rotor (position 1) Inner rotor to outer rotor tip (position 2) PBIC2827E Body to inner rotor (position 3) Body to outer rotor (position 4) PBIC2828E PBIC0821E Inner rotor to brazed portion of housing 2010 Pathfinder |
