Removal and Installation

REMOVAL

1. Remove the timing chain. Refer to EM-163, 'Removal'.

Ultima ® engines are primed from the factory but if no oil is being fed from the oil pump the lifters will lose their prime quickly. Extend the adjuster another 3 full turns beyond zero lash and lock the jam nut tight. (This applies to pushrods with 18 threads per inch. 40 98-515 Oil pump, Ultima 92-99 std.

Engine Oil and Oil Filter Replace engine oil and oil filter at the specified intervals. For recommend-ed oil grade and viscosity refer to Chapter 9 in your Owner’s Manual. Engine Valve Clearance. Inspect only if valve noise increases. Adjust valve clearance if necessary. Evaporative Emissions Control Vapor Lines. Check vapor lines and connections.

2. Remove oil pump assembly.

INSTALLATION

Installation is in the reverse order of removal.

Disassembly and Assembly

1. Oil pump housing

2. Outer rotor

3. Inner rotor

4. Oil pump cover

5. O-ring

6. Regulator valve set

7. Regulator valve

8. Spring

9. Regulator plug

10. Oil strainer

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

DISASSEMBLY

1. Remove the oil pump cover.

2. Remove inner rotor and outer rotor from oil pump housing.

3. Remove oil strainer from oil pump housing.

4. After removing regulator plug, remove spring and regulator valve.

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).

Ultima Oil Pump

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.
