Details of the oil pump

1. Pump (chain cover)
2. Reducing valve
3. Springs
4. Plate
5. Lock ring
6. Crankshaft epiploon
7. Pump cover
8. Leading rotor
9. The conducted rotor
10. Laying


1. Take off belts and a roller of a natyazhitel.
2. Remove the pallet.
3. Remove a crankshaft pulley. For access to the reducing valve uncover chains.
4. Unscrew 9 screws (ukazna shooters) and remove the case of the oil pump.
5. Remove the consolidation remains from the demountable planes of the pump and block of cylinders, wash out the planes solvent.
6. Get the conducting and conducted rotors.
7. Carefully disassemble the reducing valve.


1. Wash out all details in solvent, check existence of wear and damages.
2. Check a condition of the sliding surface of the piston of the reducing valve and a spring. At detection of damages replace the piston complete with a spring.
3. Check the probe a gap between the conducted rotor and the case.
4. Check the probe a face gap of a rotor between a rotor and a cover.
5. Check the probe a gap in gearing of the leader and conducted rotors.
6. Compare results of measurements to the standard. If gaps exceed norm, replace rotors in a set. If necessary replace a pump housing (a chain cover).


1. Oil rotors for the engine and install in the case.
2. Put technical vaseline in a pump cavity, lay laying, put a cover and tighten screws.
3. Oil the piston of the reducing valve fresh for the engine and establish valve details.
4. Establish new laying of a cover of a chain on the directing pins.
5. Establish a chain cover, having entered the roller of the leading rotor of the oil pump into gearing with the leading gear wheel of the crankshaft.
6. Establish other details upside-down.
7. Fill in oil, start the engine, be convinced of lack of leaks.
