Folksvagen Sharan/Sharan repair>> The diesel engine>> shatunno - Piston group>> Assemblage of pistons and rods
Heat up pistons to temperature 60°C (for this purpose put them in hot water). Find approaching оправку which enters in a piston finger.

Fig. 429. Removal and installation of a piston finger by means of special оправки

Hand insert a piston finger in нагретый the piston and a rod. On fig. 429 it is shown, how the piston should settle down at installation of a piston finger.
At piston and rod assemblage it is necessary to observe following recommendations:
- If reuse old pistons watch correctness of an arrangement of the marks put by you. At installation of new pistons pay attention to a mark in the form of figures on pistons, i.e. 1/2 or 3/4;

Fig. 423. By arrows cast ledges are shown. Languages of loose leaves of bearings settle down on the same party

- Cast ledges on a rod and a bearing cover (fig. 423 see) should specify towards an intermediate shaft and engine pulleys;
- The mark in the form of cylinder number should coincide on a rod and a bearing cover;
- Insert lock rings from both parties of the piston and be convinced that they strongly sit in grooves;
- Check up, whether the piston on a rod forward-back freely moves.

Fig. 430. A cut and an arrangement of piston rings at their installation on the piston

By means of a stripper for piston rings (fig. 425 see), establish piston rings by turns in grooves. If you do not have tool for installation of piston rings use metal strips (see fig. 426). For this purpose establish rings at level of grooves on the piston and, having pulled out metal strips, establish piston rings in their grooves. Check up cross-section section of rings before their installation (fig. 430). Both компрессионных piston rings on the one hand are marked by words «Oben» or "Torahs" and these marks should be visible after ring installation from outside the piston bottoms.
Before installation the collected pistons combine on a pure surface and cover to prevent hit on them a dust.
