Folksvagen Sharan/Sharan repair>> System of greasing of the engine



The system of greasing of the engine serves for oil giving to all rubbing details of the engine at its work owing to what capacity losses on a friction between details decrease and deterioration of rubbing surfaces decreases. Besides, oil, passing between rubbing details of the engine, cools them and carries away deterioration products.
Engine VR6
Greasing system the combined: under pressure, at the expense of work of the oil pump and разбрызгиванием.

Fig. 165. Details of the oil pump: 1 — the block of cylinders; 2 — a bolt, 10 Нм; 3 — a cover of a drive of the oil pump; 4 — an O-shaped sealing ring, always on replacement; 5 — a leading gear; 6 — a shaft of a drive of the pump; 7 — an intermediate shaft; 8 — an adjusting washer; 9 — a bolt, 25 Нм; 10 — the oil pump; 11 — a bolt, 10 Нм





The oil pump шестеренчатый, is located in the bottom part картера and put in action from an intermediate shaft of the engine by means of a gear wheel of an intermediate shaft 7 (fig. 165) and a leading gear wheel 5 shaft 6 drives of the pump.
The oil radiator to which hoses of system of cooling are attached, settles down on a lateral face of the block of cylinders.
The oil filter on engine VR6 folding also consists of the filter case in which the demountable filtering element is located. At oil replacement in the engine it is filled in only 5,5 l of engine oil, from them of 5,0 l of oil is in the engine and about 0,5 l — in the oil filter. At oil replacement it is necessary to remember it, especially in the event that the filter is not replaced.
Oil from the pallet картера is forced by the pump in the oil filter from which it moves in the trunk main located in the block of cylinders, whence oil is taken away on cross-section channels to bearings of cranked and distributive shaft and further to other points of greasing.
In the block of cylinders are located the valve for tap of oil and jets for greasing krivoshipno-shatunnogo the mechanism. These are unique parts of system of greasing of the engine with which it is possible to replace, only having removed the engine from the car. It is possible to replace all other parts of system of greasing on the established engine.
The two-litre engine
The engine also is oiled, circulating under pressure.

Fig. 166. System of greasing of the 2,0-litre engine: 1 — a lining, replace with the new; 2 — a cover маслоналивной mouths; 3 — щуп for check of level of oil; 4 — a directing tube щупа for check of level of oil; 5 — the switch of pressure of oil on 25 кПа; 6 — the switch of pressure of oil on 180 кПа; 7 — the return valve, 5 Нм; 8 — заглушки; 9 — a nut, 25 Нм; 10 — the basis of the oil filter; 11 — an O-shaped sealing ring, always on replacement; 12 — an oil radiator; 13 — the oil filter; 14 — a gear wheel of the oil pump; 15 — a cover of the oil pump with редукционным the valve; 16 — a bolt, 10 Нм; 17 — a bolt, 20 Нм; 18 — a bolt of fastening oil картера; 19 — a sealing ring, replace; 20 — a stopper of an aperture for oil plum; 21 — the oil pallet; 22 — a lining, replace with the new; 23 — маслоприемник; 24 — an oil directing guard; 25 — a lining, replace with the new





The oil pump also шестеренчатый, is located in the bottom part картера and put in action from an intermediate shaft of the engine by means of a gear wheel of an intermediate shaft and a gear wheel 14 (fig. 166) a pump power shaft.
The oil radiator of liquid cooling is established between the basis 10 oil filters and the oil filter 13. At oil replacement in the engine 4,7 l of engine oil are filled in, from them of 4,2 l of oil is in the engine and 0,5 l in the oil filter.
