3.15. Oil pump

Prevention

At installation of the oil pump it is necessary to use new laying of a maslopriyemny pipe and a new sealing ring of round section for an oil supply tube.

Oil pump

Removal

Removal of a maslopriyemny pipe

Removal of a cover of the oil pump

Extraction of an internal rotor of the oil pump

Extraction of an external rotor of the oil pump

Unscrewing of a stopper of the safety valve of pressure

Extraction of a spring of the safety valve of pressure

Extraction of a plunger of the safety valve of pressure

Removal of a sealing ring of round section from an oil supply pipe

The oil pump is put in action via the driving coupling from the forward end of a bent shaft and is located in a cover of a driving chain.

PERFORMANCE ORDER
1. Uncover a driving chain.
2. Unscrew two bolts and remove a maslopriyemny pipe and laying (see rice. Removal of a maslopriyemny pipe).
3. Unscrew bolts and uncover the oil pump (see rice. Removal of a cover of the oil pump).
4. Take external and internal rotors of the oil pump, noting their relative positioning (see rice. Extraction of an internal rotor of the oil pump, Extraction of an external rotor of the oil pump).
5. Sideways covers of a driving chain unscrew a stopper of the safety valve of pressure of oil and take laying, a spring and a plunger (see rice. Unscrewing of a stopper of the safety valve of pressure, Extraction of a spring of the safety valve of pressure, Extraction of a plunger of the safety valve of pressure).
6. Carefully clear all details of the oil pump and check their state. If there is a wear of rotors, they need to be replaced in a set. With wear of the case of the oil pump or a cover it is necessary to replace a cover of a driving chain. The new cover of a driving chain is delivered together with the oil pump.
7. Remove a sealing ring of round section from a pipe of supply of oil in a back part of the pump (see rice. Removal of a sealing ring of round section from an oil supply pipe).

Installation

Filling of space between teeths of rotors of the oil pump pure engine oil

PERFORMANCE ORDER
1. Install external and internal rotors in the case of the oil pump according to earlier made tags. Fill space between teeths of an external and internal rotor of the oil pump pure engine oil (see rice. Filling of space between teeths of rotors of the oil pump pure engine oil).
2. Establish a cover of the oil pump and screw bolts, having tightened them the required moment.
3. Establish new laying of a maslopriyemny pipe, and the rounded edge of laying has to be directed to the top part of a cover of a driving chain.
4. Establish a maslopriyemny pipe and fix by two bolts.
5. Establish a new sealing ring of round section on a pipe of supply of oil in a back part of the oil pump.
6. Grease with a thin layer of engine oil a plunger of the safety valve of pressure of oil and consistently establish a plunger, a spring, a sealing ring and screw up a stopper, having tightened it the required moment.
7. Establish a cover of a driving chain.
