The note
At installation it is necessary to use new sealing rings.

On engines with a lining on the bottom section of the oil pallet check up a condition and a lining arrangement.
Plastic or wooden scraper clear of an old lining привалочные surfaces of the top and bottom sections of the oil pallet.
By means of a rotating metal brush, насаженной on an electric drill, clear hermetic from the oil pallet.

Fig. 6–4. A place of drawing of a layer of hermetic in diameter of 3 mm on привалочную a surface of the oil pallet



Put a layer of hermetic D176 404 А2 in diameter 3 mm on привалочную a surface of the oil pallet (fig. 6–4).
After drawing of a layer of hermetic the oil pallet is necessary for establishing during 5 mines, to allow to dry up to hermetic of 30 mines and only after that to fill in in the engine engine oil.
The hermetic layer should be in diameter no more than 3 mm as surpluses of hermetic can get to oil and block the mesh filter.
In regular intervals on a diagonal tighten bolts of fastening of the oil pallet.
On engines with a lining on the bottom section of the oil pallet do not draw bolts, the lining of the oil pallet otherwise is deformed.
On engines in which the bottom section of the oil pallet is established on hermetic, tighten fastening bolts at first the moment 5 Нм, then definitively moment 10 Нм.
Fill in cooling liquid.
Fill in in the engine engine oil.
