Installation of pistons and rods carry out in the following order:

- plentifully grease with engine oil internal surfaces of cylinders;

Fig. 63. Details of piston group: 1 — kompressionny piston rings; 2 — a maslosjemny ring; 3 — the piston; 4 — a rod cover; 5 — a bolt of fastening of a rod; 6 — rod loose leaves; 7 — a rod; 8 — the block of cylinders; 9 — a lock ring; 10 — a piston finger; the arrow A specifies the direction to a forward part of the engine

- spread out all rods according to numbers of cylinders. Cast ledges on a rod and a cover of a rod should be directed towards a pulley of a cranked shaft (see fig. 63 ). After installation of rods cast ledges should be located on other party of an arrow;

- shooters should point to the bottom of pistons in the direction of a forward part of the engine;

- сориентируйте locks of piston rings relatively each other at an angle in 120 ° on a cylinder surface;

Fig. 66. Piston installation by means of the special VW3278 tool

- put on a coupling tape collar 3278 piston rings on the piston (fig. 66) and press piston rings into piston flutes;

Fig. 67. An alternative coupling tape collar for installation of pistons

- for this purpose it is possible to use also the replacement tool applied by Volkswagen firm — a coupling tape collar (fig. 67) ;

- check that piston rings completely entered into the flutes;

- turn a cranked shaft so that two shatunny necks of a cranked shaft appeared in the bottom dead point (NMT);

- establish the loose leaf of the bearing of a rod in a rod;

- insert a rod from above into a cylinder opening. For this purpose put the engine sideways so that the rod could be directed on a radical neck. Watch, that the opening of the cylinder and a rod neck thus were not scratched;

- insert pistons so that piston rings in turn entered into openings of cylinders and the heel of a rod sat down on a shatunny neck of a cranked shaft;

- insert the second loose leaf into a bearing cover so that the unbent short mustache of the loose leaf sat down in a groove of a cover of the bearing. Grease surfaces of loose leaves with engine oil;

- press a rod cover to a rod and easily knock on it. Grease with engine oil bolts of fastening of a rod and twist them;

- surely be once again convinced that both cast ledges are located, as is shown in fig. 56 . Both cast ledges on a rod and a cover of a rod should be located opposite and specify in the pulley direction;

- alternately tighten bolts of fastening of the bearing of a rod the moment of 30 N · m then turn them from this final situation on 90 ° (on a turn quarter);

- after installation of a rod turn a cranked shaft several times to be convinced that it rotates easily, without jammings;

- once again check marking of all rods to be convinced that cтрелки of pistons specify in the correct direction;

Fig. 68. Measurement of an axial gap between the lateral plane of the bearing of a rod and a lateral surface of a cranked shaft

- with the help щупа measure an axial gap between the lateral plane of bearings of a rod and a lateral surface of a cranked shaft (fig. 68) which should not exceed 0,31 mm;

- establish an oil case (see подразд. 4.1);

- all further works on assembly are made as it should be, the return to dismantling.
