Toyota RAV4 Service Manual: Inspection
- Inspect oil pump assembly
- Turn the drive gear with 2 screwdrivers and make sure it rotates smoothly.
Notice:
Be careful not to damage the oil seal lip.
- Inspect clearance of oil pump assembly
- Push the driven gear to one side of the body. Using a feeler gauge, measure the clearance.
Standard body clearance: 0.10 To 0.17 Mm (0.0039 To 0.0067 In.)
Maximum body clearance: 0.17 Mm (0.0067 In.)
If the body clearance is greater than the maximum, replace the oil pump body sub-assembly.
- Measure the tip clearance between the driven gear teeth and drive gear teeth.
Standard tip clearance: 0.07 To 0.15 Mm (0.0028 To 0.0059 In.)
Maximum tip clearance: 0.15 Mm (0.0059 In.)
If the tip clearance is grater than the maximum, replace the oil pump body sub-assembly.
- Using a straightedge and feeler gauge, measure the side clearance of both gears.
Standard side clearance: 0.02 To 0.05 Mm (0.0008 To 0.0020 In.)
Maximum side clearance: 0.05 Mm (0.0020 In.)
Standard drive gear thickness 
Standard driven gear thickness 
- Inspect front oil pump and gear body subassembly
- Using a caliper gauge, measure the inside diameter of the oil pump body bush.
Standard inside diameter: 38.113 To 38.138 Mm (1.50051 To 1.50149 In.)
Maximum inside diameter: 38.188 Mm (1.50346 In.)
If the inside diameter is grater than maximum, replace the oil pump body sub-assembly.
- Inspect stator shaft assembly
- Using a caliper gauge, measure the inside diameter of the stator shaft bush.
Standard inside diameter: 21.500 To 21.526 Mm (0.84646 To 0.84748 In.)
Maximum inside diameter: 21.57 Mm (0.8492 In.)
If the indicator diameter is greater than the maximum, replace the stator shaft.
