Removal
PERFORMANCE ORDER |
1. Take off a gear belt. |
2. Remove a back casing of a gear belt. |
3. Remove the oil pallet and a pipe of an oil receiver with the mesh filter. |
4. Disconnect the electric socket from the oil pressure sensor. |
5. On engines of 1,6 l unscrew a bolt of fastening of a suspension bracket of the sensor of a bent shaft and move it from the oil pump aside. |
6. Unscrew bolts and remove the oil pump from the end of a bent shaft. Remove laying of the oil pump. |

Repair
PERFORMANCE ORDER |
|
1. Unscrew screws and uncover the oil pump. |
2. Using a marker, note the mutual provision of internal and external rotors of the oil pump. |
|
3. Take an internal and external rotor of the oil pump from the case. |
4. Unscrew a bolt of fastening of the safety valve to a pump housing and take a spring and a plunger from the case. |
5. Carefully clear all details of the oil pump and check their state. If there is a wear of a rotor or the case of the oil pump, the pump needs to be replaced assembled. |
|
6. Check a gap between teeths of an internal and external rotor. Using a metal ruler, check an axial gap of rotors of the oil pump. |
|
7. Measure an axial side play of rotors of the oil pump. |
8. Assembly of the pump is carried out in the sequence, the return dismantling, taking into account the next moments:
– install rotors in the pump according to earlier put tags; – establish a new sealing ring on a bolt of fastening of the safety valve of pressure; – tighten fastening screws to a pump cover the required moment; – rotating an internal rotor, fill the pump with pure engine oil. |

Installation
PERFORMANCE ORDER |
|
1. Take a sealing ring of a bent shaft from the case of the oil pump. Using a tubular mandrel, establish a new sealing ring of a bent shaft. Grease working edges of a sealing ring with pure engine oil. |
2. Check that the interfaced surfaces of the oil pump and the block of cylinders the pure and dry, and directing pins are in the block of cylinders of the engine. |
3. Install new laying on the block of cylinders of the engine. |
|
4. Install the oil pump on a bent shaft, at the same time combine an internal rotor with sides of a bent shaft (2). Do not damage a sealing ring on the end of a bent shaft (1). |
5. Fix the oil pump by bolts, having tightened them the required moment. |
6. On engines of 1,6 l attach the sensor of a bent shaft to the case of the oil pump. |
7. Connect the electric socket of the sensor of pressure of oil. |
8. Establish an oil receiver pipe with the mesh filter and the oil pallet. |
9. Install the back protection cover of a gear belt. |
10. Establish pulleys of a gear belt, single pulleys and the mechanism of a tension. Establish a gear belt. |
11. Establish a new oil filter and fill in engine oil in the engine. |
