If the body clearance is greater than the maximum, replace the oil pump body subassembly.
2. CHECK TIP CLEARANCE OF DRIVEN GEAR
Measure between the driven gear teeth and the crescent-shaped part of the pump body.
Standard tip clearance: 0.11 - 0.14 mm (0.0043 - 0.0055 in.)
Maximum tip clearance: 0.3 mm (0.012 in.)
If the tip clearance is greater than the maximum, replace the oil pump body subassembly.
3. CHECK SIDE CLEARANCE OF BOTH GEARS
Using a steel straightedge and a feeler gauge, measure the side clearance of both gears.
Standard side clearance: 0.02 - 0.05 mm (0.0008 - 0.0020 in.)
Maximum side clearance: 0.1 mm (0.004 in.)
There are different thicknesses for drive and driven gears.
If the thickest gear can not make the side clearance within standard specification, replace the oil pump body subassembly.
