1. Attentively examine a pump asterisk on existence of signs of wear and mechanical damages. The special attention should be turned on chips in the bases of teeths - in case of this sort of detection of defects all assembly of the pump is subject to replacement (in an individual order of an asterisk are not delivered). At the same time it is necessary to replace as well a driving chain with a leading asterisk. For replacement of components of a drive of the oil pump remove a cogwheel of a cranked shaft (see. Removal, check of a condition and installation of a natyazhitel and cogwheels of a gas-distributing belt). To Otboltita from the block of cylinders the holder of an epiploon. Now the asterisk assembled with a chain and the remote plug should be removed from a shaft pin (for more details see. Removal and major maintenance of the engine).

2. Turn out three bolts of fastening of a cover of the mesh filter to the pump case. Uncover (at the corresponding complete set remove also maslootrazhatelny plate).

3. Take a spring and the piston of the reduktsionny valve from the nest in the pump case. Try to remember the adjusting provision of components.

4. Check a condition a gear wheel and pump cases. In case of identification of signs of excessive wear, задиров or other mechanical damages replace the pump assembled.
5. Check the piston of the reduktsionny valve on existence of signs wear and mechanical damages, in case of need make replacement.

Both the piston, and a spring are delivered in an individual order.
6. Carefully wash out the mesh filter of the oil pump solvent and check on existence of mechanical damages and signs of violation of passableness. The defective filter is subject to replacement assembled with a cover.

3. Establish into place the case pallet (see. Removal and installation of the pallet of a case of the engine).
4. Before primary start of the engine it is necessary to fill pump assembly by oil for what disconnect ECU systems of injection of fuel and turn the engine a starter until on an instrument guard the control lamp of pressure of oil will not go out. Do not forget to connect electroconducting to ECU again.
