15. Fill cavities and covers of internal and external hinges of equal angular speeds with MERCEDES lubricant of 100 g. You watch that dirt did not get to hinges.
16. Put on a protective cover a cover so that the sealing ledge of a cover was between cover cover ledges.
17. Put on covers small diameter a thickening of a power shaft so that after installation the flute of a power shaft was not visible. The cover thickening thus is fixed in the first flute of a shaft. Put on collars and fix them.
