2 – an external rotor
3 – a sealing ring
4 – the case of the oil pump
5 – a cover of the oil pump
6 – a stopper
7 – a washer
8 – a spring safety
The valve

Arrangement of bolts of fastening of the oil pump

Removal

PERFORMANCE ORDER
1. The oil pump is located in a forward cover of a cranked shaft and put in action directly from a cranked shaft.
2. Merge from the engine engine oil and unscrew the oil filter.
3. Lift a forward part of the car and fix on supports.
4. Remove the mechanism of a tension of a gear belt, a gear belt and a pulley of a cranked shaft.
5. Disconnect an electric socket from the gauge of pressure of oil. Remove a single pulley. Unscrew bolts, remove the oil pump (the Arrangement of bolts of fastening of the oil pump).

Check

PERFORMANCE ORDER
1. Uncover the oil pump a back part of the case of the oil pump.
2. Note a relative positioning of internal and external rotors of the oil pump for correct subsequent installation of rotors in the oil pump.
3. Take rotors from the case of the oil pump.
4. Unscrew a stopper of a safety valve and take a spring and a safety valve.
5. Carefully clear all details of the oil pump and check up their condition.
6. Check up a condition of the piston of a safety valve and a spring.
7. Using an edge щупа, check up a backlash between teeths of rotors of the oil pump.
8. Using an edge щупа, check up a backlash between an external rotor and the case of the oil pump.
9. Using глубиномер, check up axial люфт rotors of the oil pump.

Installation

PERFORMANCE ORDER
1. Grease the safety valve piston with pure engine oil and establish all elements of the valve in the case of the oil pump.
2. Grease rotors with pure engine oil and establish them in the case of the oil pump according to earlier put labels. Establish a cover of the oil pump.
3. Establish a new sealing ring of round section in the case of the oil pump and replace a forward sealing ring of a cranked shaft.
4. Apply a thin film hermetic on an interfaced surface of the case of the oil pump.
5. Establish the oil pump on the block of cylinders and fix bolts.
