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).
