Folksvagen Sharan/Sharan repair>> Engine VR6>> Pistons and rods>> Removal
Pistons and rods are beaten out from the block of cylinders in a direction upwards by the hammer handle, after removal of covers and loose leaves шатунных bearings. Before carrying out of these works it is necessary to observe following recommendations:

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

- Put (it is desirable colour) marks on each piston (fig. 54) and a rod concerning it. It is necessary to specify that number of the cylinder from which the piston and a rod have been removed;
- Draw an arrow (fig. 54 see) at the bottom of the piston, specifying in a forward part of the engine;

- Right after removals of the piston from a rod, mark a rod and a cover of the bearing of a rod sideways (fig. 55), having specified cylinder number. The rod and a cover of the bearing of a rod should be collected so that both cast ledges have been located opposite each other (fig. 56);
- Mark bearing loose leaves according to a rod and a rod cover;

The prevention
Both cast ledges after rod installation always should be located from outside a pulley of a cranked shaft.

- Mark with colour the top and bottom loose leaves of the bearing on their back party.
Removal of pistons carry out as follows:
- Remove covers of rods and loose leaves and beat out details. In case of need scratch out a scraper an oil deposit on the top part of the cylinder. For this purpose turn a cranked shaft a little to lower the piston more deeply in a cylinder aperture. Be cautious, that a scraper not to scratch the cylinder;

- By means of a sharp subject or a small punch (fig. 57) remove the spring lock rings located on each party of a piston finger. The dredging which is available in an aperture for a piston finger, facilitates punch application;
- With the help оправки beat out a piston finger. At blow watch that оправка has not jumped out and has not struck on the piston;

Fig. 58. Removal of a piston ring by means of a stripper

- Mark piston rings and remove them by means of a stripper (fig. 58);

Fig. 59. Removal of a piston ring by means of metal strips

- If the stripper for piston rings is not present, it is possible to insert under piston rings metal strips the friend opposite to the friend (fig. 59). One of metal strips enclose towards the end of a piston ring to avoid occurrence of scratches on a piston surface;
- Remove piston rings and hang up on them labels with cylinder number. At survey of piston rings be convinced that on one of the parties there is a mark «Oben» or "Top". At installation of piston rings this inscription should be visible from outside the piston bottoms.
