MR2 L4-132 2164cc 2.2L DOHC (5S-FE) (1993)
Maximum body clearance: 0.3 mm (0.012 in.)
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 straight edge 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.
Drive and driven gear thickness: 10.715 mm (0.4219 in.)
If the thickest gear can not make the side clearance within standard specification, replace the oil pump body subassembly.
4. CHECK OIL PUMP BODY BUSHING
Using a dial indicator, measure the inside diameter of the oil pump body bushing.
