Repair Sharan/Sharan Volkswagen>> Two-liter engine (ADY)>> Head of the block of cylinders and valves>> Installation of a head of the block of cylinders
Installation of a head of the block of cylinders carry out in the following order:
- clear surfaces of a head of the block of cylinders and the block of cylinders and put laying of a head of the block of cylinders so that «Oben» or "Top" inscription from above was visible. Always establish the new laying corresponding to number of this spare part;

Fig. 124. The locations of directing fingers of a head of the block of cylinders are shown by shooters




Fig. 125. Sequence of an inhaling of bolts of fastening of a head of the block of cylinders




- for the correct arrangement of laying two directing fingers should be inserted into places of fastening of bolts No. 8 and 10 (see fig. 125) on the block of cylinders 3070 (fig. 124) . At their absence to insert into the corresponding openings in a head of the block of cylinders directing pins;
- establish a head of the block of cylinders and обстучите its plastic or rubber hammer. That valves did not strike on a bottom of pistons, establish the piston of the first cylinder in situation VMT and turn a cranked shaft against the rotation direction on 90 °. Thanks to it all pistons will be located below situation VMT. Establish a head of the block of cylinders only in this provision of a cranked shaft;
- insert eight bolts of fastening of a head of the block of cylinders and twirl them by hand;
- twist directing fingers 3070 and screw instead of them the remained bolts of fastening of a head of the block of cylinders;
- according to the sequence shown on fig. 125 , gradually tighten all bolts of fastening of a head of the block of cylinders at first the moment of 40 N · m and it is final — 60 N · m; in the specified sequence insert a key into each bolt, having remembered situation a vorotka, and tighten each bolt for one approach precisely on a half of a turn or twice on a turn quarter;
- insert a key into each bolt of fastening, having remembered situation a vorotka and according to sequence (see fig. 125 ), tighten each bolt for one approach precisely on a turn quarter;
- repeat this pass in the same way once again;

Note
Not to damage at an inhaling bolts of fastening of a head of the block of cylinders, it is necessary to use only a special many-sided key similar on a shestigrannik.

- establish a gear driving belt 1 (see fig. 103 ) and adjust a drive of the mechanism of a gazoraspredeleniye;

Details of the top part of a head of the block цилиндров:1 — a bolt, 16 N · m; 2 — the central cover (over the top part of the inlet pipeline); 3 — a cover of a maslonalivny mouth; 4 — a nut, 10 N · m; 5 — a rigidity edge; 6 — a cover of a head of the block of cylinders; 7 — a maslootrazhatelny guard; 8 — a bolt of fastening of a head of the block of cylinders; 9 — laying of a cover of a head of the block of cylinders; 10 — a head of the block of cylinders; 11 — laying of a head of the block of cylinders; 12 — an elevating eye; 13 — a camshaft cogwheel; 14 — a cap; 15 — from system of ventilation of a case; 16 — T-shaped;;;;;;; 17 — an O-shaped sealing ring (always on replacement)





- paste laying 9 (see fig. 105 ) covers of a head of the block of cylinders on a head of the block of cylinders;

Prevention
Always establish new sealing laying. In order to avoid infiltration of oil pay attention to the correct installation of laying.

- put on a cover of a head of the block of cylinders. At the left and to the right of a cover of a head of the block of cylinders put on adjusting pins strengthening and evenly around tighten nuts with the moment of 10 N · m;
- the remained operations carry out to sequences, return to removal, being guided thus by drawings on assembly;
- after completion of all operations fill in liquid in cooling system.
