SLC494A SLC495A SLC450AA INSPECTION NMLC0007 Using a feeler gauge, check the following clearances: Unit: mm (in) Body to outer rotor radial clearance 1 0.114 - 0.200 (0.0045 - 0.0079) Inner rotor to outer rotor tip clearance 2 Below 0.18 (0.0071) Body to inner rotor clearance 3 0.05 - 0.09 (0.0020 - 0.0035) Body to outer rotor axial clearance 4 0.05 - 0.11 (0.0020 - 0.0043) Inner rotor to brazed portion of housing clear- 0.045 - 0.091 (0.0018 - 0.0036) I If the tip clearance (2) exceeds the limit, replace rotor set. I If body to rotor clearances (1, 3, 4, 5) exceed the limit, SLC403B REGULATOR VALVE INSPECTION NMLC0008 1. Visually inspect components for wear and damage. 2. Check oil pressure regulator valve sliding surface and valve 3. Coat regulator valve with engine oil. Check that it falls I If damaged, replace regulator valve set or oil pump assem- SLC451A 4. Check regulator valve to oil pump cover clearance. Clearance: 6: 0.040 - 0.097 mm (0.0016 - 0.0038 in) I If it exceeds the limit, replace oil pump cover.
