1. Establish an external rotor and an internal rotor. |
2. Measure a gap between a casing of the oil pump both external and internal rotors, not less than in four places on their circles. Gap Nominal gap: 0,02–0,04 mm Maximum permissible gap: 0,05 mm
|
3. If the gap differs from demanded, replace the oil pump assembled. |
4. Measure a gap between a ledge of the oil pump and an internal rotor, at least, in four places and calculates average value. Internal diameter Nominal: 0,04–0,115 mm Maximum permissible: 0,125 mm
|
5. If the gap differs from demanded, replace the oil pump assembled. |
6. Check the spring sizes in a free state.
Outer diameter: 11,8 mm Length: 53,0 mm Number of rounds: 12,0
Diameter of a wire of a spring: 1,2 mm |
 |
7. If the sizes of a spring differ from demanded, replace the oil pump assembled. |
 |
8. Measure the outer diameter of the valve of pressure.
Nominal diameter: 14,00 mm Maximum permissible diameter: 13,98 mm
|
9. If diameter is less maximum permissible, replace the oil pump assembled.
