Folksvagen Sharan/Sharan repair>> The two-litre engine (ADY)>> Pistons and rods>> Assemblage of pistons and rods Correctly to collect a rod with the piston and to establish it in the engine in appropriate position, take advantage before put of marks. If replacement of pistons check up that all pistons concerned one type has been made.
At piston and rod assemblage observe following recommendations:
- The arrow on the piston bottom (either drawn, or beaten out if the piston new) should specify in a direction of a forward part of the engine (fig. 130 see);
- Cast ledges on a rod and a rod cover (fig. 56 see) should specify in a direction of an asterisk of a cranked shaft of the engine;
- Marks of number of the cylinder (fig. 55 see) should be identical to a rod and a rod cover.
Assemblage of pistons and rods spend in a following order:
- Heat up the piston to temperature 60 ° C (for this purpose put it in hot water) and pick up оправку which should enter in a piston finger;
- Heat up a rod;
- By hand with the help оправки insert a piston finger in нагретый the piston and a rod (fig. 133). If the piston very hot it can be wrapped up a rag;
- Establish spring lock rings 2 (fig. 132) on both parties of a piston finger 3 see and be convinced that they densely sit in grooves;
- Check up: the rod after assemblage freely moves forward-back (fig. 65 see). It should move smoothly, should not be felt any jammings;
- Grease with flute engine oil on the piston and piston rings and by means of special nippers for installation of piston rings (fig. 58 see) establish piston rings in flutes. If on a ring the label «Oben» or "Torahs" a ring establish a label upwards (to the piston bottom) is put. Компрессионные piston rings are easy for mixing. For this reason it is necessary to look before installation at their cross-section section;
- If special nippers for installation of piston rings are not present, it is possible to use metal strips (fig. 59 see). 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.
