Removing ( Refitting ) 1. Undo the bolts fixing the engine oil intake.2. Remove the engine oil intake. Refitting ( Removing ) Secure the oil pump appropriately.1. Measure the clearance between the pump casing and the gears and make sure it is within the recommended values.

	Measurement		Value
1	Radial clearance between pump casing and gears (mm)		0.110 - 0.180

1. Check the endfloat between cover support plane and the surface of the gears.

	Measurement		Value
1	Endfloat between pump support plane and gears (mm)		0.040 - 0.106

Calculate the clearance between the internal diameter of the driven gear and the pump casing housing bearing.

	Measurement		Value
-	Clearance between driven gears internal diameter and pump casing housing bearing (mm)		0.015 - 0.048

Calculate the clearance between the diameter of the drive gear shaft and the pump casing housing.

	Measurement		Value
-	Clearance between drive gear shaft diameter and pump casing housing (mm)		0.016 - 0.048

Calculate the clearance between the drive gear and the driven gear.

	Measurement		Value
-	Clearance between drive gear and driven gear (mm)		0.30

Use suitable equipment to check the specifications of the relief valve spring.

	Measurement		Value
-	Relief valve spring height (mm)		22.5
	Under a load of (daN)	6.51 - 6.82

	Measurement		Value
-	Relief valve spring height (mm)		21
	Under a load of (daN)	6.92 - 7.21

If even only one of the checks carried out of the pump casing, the gears or the valve gives results that are outside of the tolerance, then the oil pump assembly must be replaced.
