Oil Pump: Service and Repair

REMOVAL AND INSTALLATION





^ Always replace with new oil seal and gasket.
^ When removing oil pump, turn crankshaft so that No. 1 piston is at TDC on its compression stroke.
^ When installing oil pump, apply engine oil to gears, then align punchmark on drive spindle and oil hole on oil pump.

REGULATOR VALVE INSPECTION





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.
^ Replace regulator valve set or oil pump assembly, if damaged.

^ The new and previous oil filter designs differ from each other and are not interchangeable.
^ Use Tool KV10115801 (J38956) for removing oil filter.

OIL PUMP INSPECTION








Using a feeler gauge, check the following clearances.





Standard clearance:

^ If the tip clearance (1) exceeds the limit, replace gear set.
^ If body to gear clearances (2, 3) exceed the limit, replace oil pump assembly.
