INSPECTION AFTER DISASSEMBLY
Oil Pump Clearance

Measure the clearance with feeler gauge.
–Clearance between oil pump outer rotor and oil pump body
(Position “1”)
–Tip clearance between oil pump inner rotor and oil pump outer
rotor (Position “2”)

Measure the clearance with feeler gauge and straightedge.
–Side clearance between oil pump inner rotor and oil pump body
(Position “3”)
–Side clearance between oil pump outer rotor and oil pump body
(Position “4”)

Calculate the clearance between oil pump inner rotor and oil pump body as follows:
OIL PUMP BODY INNER DIAMETER
–Measure the inner diameter of oil pump body with inside
micrometer. (Position “5”)
OIL PUMP INNER ROTOR OUTER DIAMETER
–Measure the outer diameter of protruded portion of oil pump
inner rotor with micrometer. (Position “6”)
OIL PUMP INNER ROTOR TO OIL PUMP BODY CLEARANCE
–(Clearance) = (Oil pump body inner diameter) – (Oil pump inner rotor outer diameter)

If measured/calculated values are out of the standard, replace oil pump assembly.Standard : 0.114 - 0.260 mm (0.0045 - 0.0102 in)
Standard : Below 0.180 mm (0.0071 in)
SLC932A
Standard : 0.030 - 0.070 mm (0.0012 - 0.0028 in)
Standard : 0.030 - 0.090 mm (0.0012 - 0.0035 in)
SLC933A
PBIC0821E
Standard : 0.045 - 0.091 mm (0.0018 - 0.0036 in)

OIL PUMP
Revision: 2006 November2007 350Z
Regulator Valve Clearance
(Clearance) = (Valve hole diameter) – (Regulator valve outer diame-
ter)

If the calculated value is out of the standard, replace oil pump
assembly.
CAUTION:

Coat regulator valve with engine oil.

Make sure that it falls smoothly into valve hole by its own
weight.
ASSEMBLY
Note the following, and assemble in the reverse order of disassembly.

Install oil pump inner rotor with the groove faced to oil pump
cover side.Standard : 0.040 - 0.097 mm (0.0016 - 0.0038 in)
