Apply a layer of D176 404 A2 sealant with a diameter of 3 mm on the privalochny surface of the oil pallet (fig. 6-4).
After drawing a layer of sealant the oil pallet needs to be installed within 5 min., to allow to dry up to sealant of 30 min. and only after that to fill in engine oil in the engine.
The layer of sealant has to have a diameter no more than 3 mm as surplus of sealant can get to oil and block the mesh filter.
Evenly on diagonal tighten bolts of fastening of the oil pallet.
On engines with laying on the lower section of the oil pallet do not draw bolts, otherwise laying of the oil pallet is deformed.
On engines in which the lower section of the oil pallet is established on sealant tighten fastening bolts at first the moment of 5 N · m, then finally the moment of 10 N · m.
Fill in cooling liquid.
Fill in engine oil in the engine.
