3.9.9. Assemblage of shatunno-piston group

PERFORMANCE ORDER
1. As the finger is inserted into the top head of a rod with a tightness, heat up a rod to 240 ° With for expansion of its head. For this purpose rods place in the electric furnace, directing the top heads of rods in the furnace.
2. In the furnace, already нагретую to 240 ° With, rods place for 15 minutes
3. For correct connection of a finger with a rod, запрессовывайте a finger as soon as possible as the rod is cooled quickly and after cooling it will be impossible to change finger position.
4. A finger 2 in advance prepare for assemblage, having put on it the platen of 1 adaptation A.60325, having established on the end of this platen directing 3 and having fixed its screw 4. The screw tighten leaky that there was no jamming at expansion of a finger from contact with нагретым a rod.
5. The rod taken from the furnace quickly clamp in a vice. Put on the piston a rod, watching, that the aperture under a finger coincided with an aperture of the top head of a rod.
6. Adaptation A.60325 the fixed piston finger 2 push in an aperture of the piston and in the top head of a rod so that заплечник adaptations adjoined to the piston (1 – adaptation A.60325). During this operation the piston should nestle a lug on the top head of a rod in a direction запрессовки a finger (it is shown by an arrow). Thus the finger will occupy correct position.

The prevention

If on the bottom head of a rod there is an aperture for an oil exit the piston should be connected to a rod so that a label «П» on the piston and an aperture on a rod were on the one hand.


7. After rod cooling oil a finger for the engine through apertures in piston lugs.
8. At installation of piston rings their locks have through 120 °. Rings establish so that bore on an external surface of the second (scraper) компрессионного rings has been turned downwards, and facets on an external surface маслосъемного rings have been turned upwards (fig. the Basic sizes of the piston, a rod, a piston finger and piston rings see).
9. The rod is processed together with a cover, therefore covers of rods are not interchangeable. That them not to mix at assemblage, on a rod and a cover corresponding to it cylinder number in which they are established is branded. At figure assemblage on a rod and a cover should be on the one hand.
