Check of a state

PERFORMANCE ORDER
1. Unscrew screws and a bolt, uncover the pump the back of a cover of the chain drive of cam-shafts.
2. Turn out a cap of the reducing valve from the basis of a cover of the chain drive, get a sealing washer. Get a spring and the piston of the reducing valve, having paid attention to the correct orientation of the piston.
3. Get the conducting and conducted rotors of the oil pump from a cover of the chain drive.
4. Examine rotors, the piston of the reducing valve and a cover of the pump, check existence of strong indications of wear or damages on these details.
5. Establish rotors in a cover and check probes a gap between the conducted rotor and a pump housing, and also a gap between teeths of the conducted and conducting rotors.
6. Also check a gap between teeths of the conducted and conducting rotors.
7. Check in the caliber laid on the top plane of a pump housing, and the probe an axial side play of the conducted and conducting rotors.
8. If there are corresponding measuring devices, then measure the outer diameter of the conducted rotor and internal diameter of a pump housing. Define a gap between the conducted rotor and a pump housing which is equal to a difference of internal diameter of a pump housing and outer diameter of the conducted rotor.
9. In the presence of signs of damages and also if any measured gaps of the pump exceed norm, replace a cover of the chain drive.
10. At detection of strong wear of rotors check also a condition of the reducing valve. The reducing valve is located in the case of an oil filter which will be screwed in a back part of the block of cylinders. Turn out a valve bolt from the top part of the case of an oil filter, get a sealing washer, a spring and a ball. Examine all details, check existence of signs of wear, in need of a detail replace. At assembly install in the case a ball with a spring, dress a new sealing washer on a valve bolt, wrap a bolt and tighten with the set moment.
11. Oil rotors of the oil pump fresh for the engine and install in the case. The conducted rotor has to be turned by a fillet outside.
12. Establish a cover, previously having convinced of purity of the demountable plane. Turn and tighten a bolt and screws of a cover with the set moment.
13. Install the piston of the reducing valve, without breaking former orientation, then establish a spring.
14. Dress a new sealing washer on a bolt of the regulator and wrap a valve bolt with a washer.

15. Tighten a bolt with the set moment.

Assembly

Collect and establish a cover of the chain drive (see subsection 3.2.1.6).
