Folksvagen Sharan/Sharan repair>> Engine VR6>> Pistons and rods>> Installation of pistons and rods
Installation of pistons and rods spend in a following order:
- Plentifully grease with engine oil internal surfaces of cylinders;

Fig. 63. Details of piston group: 1 — компрессионные piston rings; 2 — маслосъемное a 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; arrow A specifies a direction to a forward part of the engine





- Spread out all rods according to numbers of cylinders. Cast ledges on a rod and a rod cover should be directed towards a pulley of a cranked shaft (fig. 63 see). After installation of rods cast ledges should be located on other party of an arrow;
- Arrows should specify in the bottom of pistons in a direction of a forward part of the engine;
- сориентируйте locks of piston rings rather each other at an angle in 120 on a cylinder surface;

Fig. 66. Installation of the piston by means of special tool VW3278





- 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 firm "Volkswagen" — a coupling tape collar (fig. 67);
- Check up that piston rings have completely entered into the flutes;
- Turn a cranked shaft so that two шатунные necks of a cranked shaft have appeared in the bottom dead point (НМТ);
- Establish the loose leaf of the bearing of a rod in a rod;
- Insert a rod from above into a cylinder aperture. For this purpose put the engine sideways so that the rod could be directed on a radical neck. Watch, that the aperture of the cylinder and a rod neck thus have not been scratched;
- Insert pistons so that piston rings have by turns entered into apertures of cylinders and a heel of a rod of village on шатунную a neck of a cranked shaft;
- Insert the second loose leaf into a bearing cover so that the unbent short moustache of the loose leaf of villages 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;

- Necessarily once again be convinced that both cast ledges are located, as is shown in fig. 56. Both cast ledges on a rod and a rod cover should be located opposite and specify in a pulley direction;
- Alternately tighten bolts of fastening of the bearing of a rod the moment 30 Нм then turn them from this final position on 90 (on a turn quarter);
- After rod installation turn a cranked shaft some times to be convinced that it rotates easily, without jammings;
- Once again check up marks of all rods to be convinced that cтрелки pistons specify in a correct direction;

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





- With the help щупа measure an axial backlash between a 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 oil картер (see подразд. 4.1);
- All further works on assemblage are made in an order, the return to dismantling.
