4.1.13. Greasing system

THE GENERAL DATA

Greasing system

1 – the oil pump, 2 – the oil pallet, 3 – the oil filter, 4 – the index of level of oil

The oil pump takes away engine oil from картера and under pressure submits it through the short channel to полнопроточному to the oil filter. The safety valve being in the pump regulates the maximum pressure created by the pump. At excess of pressure created by the pump, the valve opens and перепускает oil in картер. The cleared oil through the filter arrives in the main oil highway. In case of a filter contamination opens редукционный the valve and an oil part, without clearing, directs to the trunk main.

From the trunk main oil on five small channels arrives to radical necks of a cranked shaft. Through diagonal apertures in a cranked shaft oil arrives to шатунным to necks and further is sprayed on walls of cylinders.

From the trunk main oil arrives to an intermediate shaft and further to the ignition distributor. Simultaneously, engine oil through three маслопровода moves directly to cam-shaft bearings. From the average bearing, through распылительные маслопроводы oil moves on all cams and levers.

Ventilation system картера

1 – the adjusting valve, 2 – a separator, 3 – the filter in an oil cover

Through an oil separator (2) with the adjustable valve (1) картерные gases are taken away in an inlet collector. Ventilation картера depends on a stream of sucked in air working engine. The adjusting valve as well as in an oil stopper, it is necessary to wash out the filter in fuel through each 20 000 km of run. Valve replacement is necessary for making through each 40 000 km of run of the car.

Check of pressure of oil

The oil pump

1 – the case, 2 – an external gear wheel, 3 – an internal gear wheel, 4 – a cover, 5 – a grid маслоприемника, 6 – a tube маслоприемника, 7 – a lining, 8 – a safety valve

Installation of a manometre for check of pressure of oil

Installation of the pipeline of giving of oil to cam-shaft bearings

Fastening of the oil pump

1 – bolts of fastening of the pump, 2 – the pump, 3 – a tube маслоприемника

PERFORMANCE ORDER

1. To warm up the engine to normal working temperature. 2. To disconnect an electric wire from the gauge of a control bulb of pressure of oil and to unscrew its gauge (in the cars equipped with a manometre of pressure of oil to disconnect the union of its pipeline). 3. To screw up in an aperture in the block of cylinders a control manometre. 4. To start the engine and to check up pressure of oil at number of turns of idling and above 2000 rpm. Pressure of oil should make a minimum 100 кПа, but not above 500 кПа. 5. To unscrew a manometre and to screw up the gauge of a control bulb of pressure of oil.

Replacement масяного the filter

PERFORMANCE ORDER

1. To unscrew from the block of cylinders the oil filter. 2. To oil a surface of a lining of the new oil filter. 3. To screw up the oil filter to a lining contact about a surface of the block of cylinders. Then to tighten the filter a hand on 3/4 turns.

Repair of the oil pump

---

The prevention

Gear wheels of the oil pump are picked up by steams and in case of need it is necessary to replace both gear wheels.

---

PERFORMANCE ORDER

1. To put on a back surface of an external gear wheel (большей) a sign for its installation in the same position concerning an internal gear wheel (smaller) in the course of assemblage in what it has been taken from a factory packing. 2. To remove the oil pallet of the engine. 3. To remove the oil pump, having unscrewed three bolts of fastening of the pump to the block of cylinders. 4. To uncover the oil pump and to take gear wheels, and also to remove the pipeline of giving of oil to the pump. 5. To punch an aperture in the middle of a rubber stopper перепускного the pump valve. 6. To take a rubber stopper by means of a bolt of the corresponding diameter. 7. To take a spring and the piston перепускного the valve. 8. To insert both gear wheels into the pump case, observing their correct relative positioning. 9. By means of a ruler and щупа to measure backlash size between a plane of the case of the pump and back planes of gear wheels. If it exceeds as much as possible admissible value, it is necessary to replace the pump case. 10. With the help щупа to check up a backlash between an external gear wheel and the pump case. If it exceeds as much as possible admissible value, it is necessary to replace the pump case. 11. To grease parts перепускного the valve with engine oil and to establish перепускной the valve. 12. To establish a rubber stopper перепускного the valve the flat party outside. It should be on the brink of a condensed surface of the pipeline of giving of oil to the pump. 13. To grease with engine oil both gear wheels of the pump. 14. To establish a cover of the oil pump and to tighten its bolts the corresponding moment. 15. To insert a shaft transferring a drive from an intermediate shaft (the end with an asymmetrical ledge should be directed towards the ignition distributor), to a shaft of a drive of the pump and, turning his hand to be convinced that pump gear wheels co-operate without jammings. 16. To establish a lining and the pipeline of giving of oil to the pump. 17. To establish the oil pump in the block of cylinders, tightening fastening bolts the corresponding moment. 18. To attach the oil pallet to the block of cylinders. It is necessary to begin with a bolt () to (), and then from a bolt () to ().
