Repair Sharan/Sharan Volkswagen>> Two-liter engine (ADY)>> 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 one type.
At assembly of the piston and a rod observe the following recommendations:

Fig. 130. 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. 130 );

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 it in hot water) and pick up an opravka which should enter in a piston finger;
- heat up a rod;

Fig. 133. Installation of a piston finger by means of an opravka





- by hand by means of an opravka insert a piston finger into the warm piston and a rod (fig. 133) . If very hot, it it is possible to wrap up the piston a rag;

Fig. 132. Details of shatunno-piston group: 1 — piston rings; 2 — a lock ring; 3 — a piston finger; 4 — the piston; 5 — a rod; 6 — a bolt of fastening of a rod; 7 — the loose leaf of the bearing of a rod; 8 — the block of cylinders; 9 — a cover of the bearing of a rod; 10 — a rod nut; And — labels on a rod and a cover; In — the provision of cast ledges





- establish spring lock rings 2 (see fig. 132 ) on both parties of a piston finger 3 and be convinced that they densely sit in grooves;

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





- check: the rod after assembly freely moves forward-back (see fig. 65 ). It should move smoothly, should not be felt any jammings;

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





- grease with engine oil of a flute on the piston and piston rings and by means of special nippers for installation of piston rings (see fig. 58 ) 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). Kompressionnye is easy for mixing piston rings. For this reason it is necessary to look before installation at their cross-section section;

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





- if special nippers for installation of piston rings are not present, it is possible to use metal strips (see fig. 59 ). For this purpose put on rings metal strips and bring them on level of piston flutes. Then, pull out metal strips and establish piston rings in flutes.
