8–sealing ring

Removal of an external rotor of the oil pump

Removal of a safety valve of pressure

Check of the piston of a safety valve of the oil pump

Places of drawing of hermetic on a cover of the oil pump

Removal

Removal of an internal rotor of the oil pump

PERFORMANCE ORDER
1. Remove a gear belt
2. Remove pulleys of the oil pump and a cranked shaft.
3. Remove the main unit of the oil pallet.
4. Unscrew bolts and uncover the oil pump the end of a cranked shaft.
5. Using a marker, note the mutual provision of an internal and external rotor of the oil pump.
Remove an internal and external rotor of the oil pump (see fig. Removal of an internal rotor of the oil pump).
If it is necessary, unscrew a bolt of a safety valve of pressure, remove a sealing ring.

Check

Gap measurement between rotors of the oil pump

Gap measurement between an external rotor and the case of the oil pump

PERFORMANCE ORDER
1. Clear details of the oil pump and check them on wear existence.
2. Using an edge щупа, check a gap between teeths of a rotor of the pump and between an external rotor and the case of the oil pump (see fig. Gap measurement between rotors of the oil pump, gap Measurement between an external rotor and the case of the oil pump).
3. Check, that the piston protect the telny valve easily and freely moved under the influence of a spring.

Installation

PERFORMANCE ORDER
1. Establish a new sealing ring on a safety valve of pressure and screw up the valve in the block of cylinders, having tightened it the demanded moment.
2. Grease a pump rotor with pure engine oil and establish in the pump case according to earlier made label.
3. Replace sealing rings of the oil pump and a cranked shaft.
4. Check that interfaced surfaces of the case of the oil pump and a pump cover, pure and dry.
5. Apply a thin film hermetic on an interfaced surface of a cover of the oil pump and, being careful, establish a cover of the oil pump.
6. On a carving of bolts of fastening of a cover of the pump put hermetic and screw up screws, having tightened them the demanded moment.
7. Establish pulleys of the oil pump and a cranked shaft. Establish the oil pallet.
8. Fill in in the engine pure engine oil.
