Removal, service and installation of the oil pump

REMOVAL

 PERFORMANCE ORDER

 At removal of the pump from the engine weaken a stopper of the reducing valve.


1. Disconnect a negative wire from the battery.
2. The car also establish to Poddomkratta it on props.
3. Remove protection of a case.
4. Empty the cooling system (see the Head Routine maintenance).
5. Lower the car on the earth.
6. Remove a radiator (see the Head of the Cooling system, heating).
7. Remove the sensor of provision of a cranked shaft (CKP).
8. Take off V-shaped driving belts.

9. Remove a natyazhitel of a back V-shaped belt.


10. Remove a pulley of a cranked shaft (see the Section Removal and installation of a pulley of a cranked shaft).
11. Remove the water pump (see the Head of the Cooling system, heating).
12. On models remove from RKPP directing a gas-distributing belt (see the Section Removal and installation of a belt of the GRM drive, check of a condition of components).

13. Remove a cogwheel of a cranked shaft.

14. Turn out bolts of fastening of the oil pump to the block of cylinders.

15. Having hooked a screw-driver with a flat sting, remove the oil pump, - try not to damage the interfaced surfaces of pump assembly and the block.

DISMANTLING

 PERFORMANCE ORDER

 The stopper of the reducing valve has to be weakened during removal of pump assembly from the engine.

Turn out fixing screws and uncover the oil pump. Before extraction of rotors mark their situation from each other.

ASSEMBLY

 PERFORMANCE ORDER

1. Check a condition of the case of pump assembly. Estimate degree of wear of an opening under a shaft, make sure of lack of violation of passability of oil channels, signs of wear of walls of a rotor chamber and other mechanical damages.

2. By means of a special mandrel of ST 499587100 put the NEW forward epiploon in pump assembly.

 Use a new epiploon.

3. Oil external and internal rotors the motive.
4. Establish rotors in the former provisions according to the marking put in the course of dismantle.
5. Check a condition of components of the reducing valve (see the following subsection).
6. Establish components of the reducing valve. Screw a stopper and tighten it with the demanded effort (44 Nanometers).
7. Make check of working gaps of rotors (see the following subsection).
8. Establish a cover of the oil pump. Tighten fastening bolts with necessary effort.

CHECK

 PERFORMANCE ORDER

1. Measure gap size between tops of teeths of rotors. Compare result of measurement to requirements of Specifications, in case of need replace both rotors.

2. Measure gap size between the forming surface of an external rotor and a wall of a rotor chamber. Compare result of measurement to requirements of Specifications, in case of need replace a rotor.

3. Measure the size of an axial side play of an internal rotor. Compare result of measurement to requirements of Specifications, in case of need replace a rotor, or the assembly case.

4. Estimate degree of wear of components of the reducing valve. Measure free and adjusting lengths of a valvate spring, and also effort of adjusting compression. Compare results of measurements to requirements of Specifications. Replace defective components.
5. Check epiploon edges for existence of deformations, hardenings, wear, etc. and replace it in case of need.

INSTALLATION

 PERFORMANCE ORDER

1. Installation is made as it should be, the return to a removal order, taking into account the listed below moments.

2. Apply on the interfaced surface of pump assembly sealant like Three Bond 1215, - sealant is imposed from the inside of botovy openings. Establish the NEW sealing ring (A) (see in the same place).

3. Moisten sealing sponges of an epiploon with motive oil.

4. Be careful, - try not to damage an epiploon at installation of pump assembly.
5. Correctly develop pump assembly of rather cranked shaft (be guided on adjusting risk), then accurately fill it on the seat on the block, - track that sealing sponges of an epiploon did not hesitate.

6. Screw fixing bolts and tighten them with the demanded effort.
