Always use a new gasket, even if the old still has a good view. As already mentioned, a number of motors are installed on the metal gasket;

- For precise installation in holes shown in Fig. 53, the guide must be screwed two bolts (holes 1 and 3 in the diagram tightening). In the absence of these special bolts (tool number 3070) should prepare two pins with a corresponding thread, if necessary, cut it, cut it out and at the ends of screwdriver slot;

- Set the cylinder head and knock on it a plastic or rubber mallet to complete the landing;

- Set the remaining eight oiled bolts of the cylinder head and tighten them by hand. Unscrew the two pins with a screwdriver, insert and screw bolts lubricated the cylinder head;

- Gradually tighten the bolts of the cylinder head (see. Fig. 26). To tighten the screws, you can only use a special key, because otherwise they will be damaged head.

Tightening carried out in four stages:

- Tighten all bolts in the indicated in Fig. 26 sequence to 40 N ?� m (first tightening bolt number 10);

- Tighten all bolts in the specified sequence to 60 N ?� m;

- Tighten each bolt 1/4 of a turn (90 ?�) in the sequence by inserting the key into the bolt and noting the position of the T-shaped handle;
