Repair Sharan/Sharan Volkswagen>> VR6 engine>> Pistons and rods>> Assembly of pistons and rods
Correctly to collect a rod with the piston and to establish it in the engine in appropriate situation, use earlier put marking. If replacement of pistons was made, check, that all pistons belonged to identical type.
At assembly of the piston and a rod observe the following recommendations:

Fig. 54. Marking of the bottom of pistons before their removal





- an arrow on the piston bottom (either drawn, or beaten out if the piston new) should specify in the direction of a forward part of the engine (see fig. 54 );

Fig. 56. Assembly of a rod and cover of the bearing of a rod. Shooters showed ledges





- cast ledges on a rod and a rod cover (see fig. 56 ) should indicate in the direction of an asterisk of a cranked shaft of the engine;

Fig. 55. Marking of a rod and cover of the bearing of a rod





- marking of number of the cylinder (see fig. 55 ) should be identical to a rod and a rod cover.
Assembly of pistons and rods carry out in the following order:
- heat up the piston to temperature 60 ° C (for this purpose put them in hot water) and pick up an opravka which enters in a piston finger;
- heat up a rod;
- by hand by means of an opravka insert a piston finger into the warm piston and a rod;

Fig. 65. Check of ease of a course of a rod





- check that the rod after assembly freely moves forward back (fig. 65) ;
- grease with engine oil of a flute on the piston and piston rings and by means of a stripper (see fig. 65 ) establish piston rings in flutes. If on a ring the label of "Oben" or "Torahs" is put, a ring establish a label up (to the piston bottom).
