Outer Rotor Side Clearance

See Figure 7-81.

Figure 7-81

1.

Place a straightedge (1) across the oil pump rotor 
bore. Use a feeler gauge (2) to measure the 
clearance between the straightedge and the outer 
rotor side surface. If measurement is beyond service 
limit, replace the oil pump assembly.

Oil Pump Outer Rotor Side Clearance Limit:
0.003—0.005 in. (0.076—0.127 mm)

Inner Rotor and Pump Case Clearance

See Figure 7-82.

Figure 7-82

1.

Using a micrometer, measure the outside diameter of 
the inner rotor shoulder (1).

2.

Measure the inside diameter of the oil pump bore 
hole (2). If measurements are not within service limit, 
replace oil pump assembly.

Inner Rotor and Pump Case Clearance: 
0.001—0.003 in. (0.025—0.076 mm)

Relief Valve Spring

See Figure 7-83.

Figure 7-83

1.

Use a veneer caliper to measure the free length of 
relief valve spring (1). If relief valve spring measures 
less than specification, replace the spring.

Oil Pump Relief Valve Spring Free Length: 2.063 in. 
(52.40 mm)

2.

Using a spring compression gauge (2), compress 
relief valve spring to specification and record the 
force reading. If force reading is less than 
specification, replace the spring.

Oil Pump Relief Valve Spring Tension at 1.516 in.
(38.5 mm) of Length: 17.3 lb-ft (23.45 N•m)
