Mark oil pump rotor locations before removing. See Fig. 30. Remove outer rotor and measure thickness and diameter. Measure inner rotor thickness. Inspect shaft for scoring or wear. Inspect rotors for pitting or damage.
Inspect cover for grooving or wear. Replace worn or damaged components.
Measure outer rotor-to-body clearance. Replace pump assembly if clearance exceeds specification. Measure clearance between rotors. See Fig. 31. Replace shaft and both rotors if clearance exceeds specification.
Install rotors in pump body. Position straightedge across pump body. Using feeler gauge, measure clearance between rotors and straightedge. Pump cover wear is measured using a straightedge and feeler gauge. Replace pump if clearance exceeds specification.

Mark oil pump gear location before removing. See Fig. 32. Remove gears from pump body. Inspect gears for pitting or damage. Inspect cover for grooving or wear. Measure gear diameter and length. Measure gear housing cavity depth and diameter. See Fig. 33. Replace worn or damaged components.
Pump cover wear is measured using a straightedge and feeler gauge. Replace pump or components if warpage or wear exceeds specification, or mating surface of pump cover is scratched or grooved.

Inspection
1. Reverse Shift Lever Clearance - Inspect
Measure the clearance between the reverse shift lever (A) and the
reverse shift fork
(B) with a feeler gauge (C). If the clearance exceeds the service limit, go
to step 2.
Standard: 0.40-0.85 mm (0.0157-0.0335 in)
Service Limit: 0.85 mm
