OIL LINE HOOK-UP V-SERIES 2 3 OWNERS MANUAL - S&S® V(SERIES ENGINES OIL RECOMMENDATIONS S&S recommends synthetic engine oil such as S&S Premium Synthetic 20W50. However a premium petroleum based engine oil such as S&S Heavy Duty 20W50 or 25W60 is acceptable. Regardless of what type of oil you select, be sure to use only oil. The oil pump used in the Nissan Altima is a sump pump that secures to the oil pickup tube inside the oil pan. To get to the oil pump so you can replace it, you must remove the oil pan from the engine. This makes the job somewhat labor intensive and time-consuming. However, if you continue to drive your Altima.

INSPECTION AFTER DISASSEMBLY

Clearance of Oil Pump Parts

• Measure clearance with feeler gauge.

• Clearance between outer rotor and oil pump body (position 1).

Standard : 0.114 - 0.260 mm (0.0045 - 0.0102 in)

• Tip clearance between inner rotor and outer rotor (position 2).

Standard : Below 0.180 mm (0.0071 in)

• Measure clearance with feeler gauge and straightedge.

• Side clearance between inner rotor and oil pump body (position 3).

Standard : 0.030 - 0.070 mm (0.0012 - 0.0028 in)

• Side clearance between outer rotor and oil pump body (position 4).

Standard : 0.050 - 0.110 mm (0.0020 - 0.0043 in)

• Calculate the clearance between inner rotor and oil pump body as follows.

1. Measure the outer diameter of protruded portion of inner rotor (position A).

2. Measure the inner diameter of oil pump body with inside micrometer (position B).

(clearance 5) = (inner diameter of oil pump body B) – (outer diameter of inner rotor A)

Standard : 0.045 - 0.091 mm (0.0018 - 0.0036 in)

Regulator Valve

1. Visually inspect components for wear and damage.

2. Check oil pressure regulator valve sliding surface and valve spring.

3. Coat regulator valve with engine oil. Check that it falls smoothly into the valve hole by its own weight.

If damaged, replace regulator valve set or oil pump body.

Regulator Valve Clearance

(Clearance 6) = D (Valve hole diameter) – E (Outer diameter of valve)

Standard : 0.040 - 0.097 mm (0.0016 - 0.0038 in)

If it exceeds the standard, replace the oil pump body.

CAUTION: Coat regulator valve with engine oil.

Check that it falls smoothly into the valve hole by its own weight.

Assembly

Assembly is in the reverse order of disassembly.

• Assemble the inner rotor and outer rotor with the punched marks on the oil pump cover side.

CAUTION: Before assembly apply new engine oil to the parts as specified.
