188.8.131.52. Check of a gap between the piston and a finger
Check of correctness of selection of a piston finger of the engine of fashion. 2106
Check of landing of a piston finger of the engine of fashion. 2106
The finger is pressed in the top head of a rod with a tightness and freely rotates in piston lugs with a gap 0,08... 0,016 mm.
Fingers, and also openings in lugs of the piston divide by the sizes into three groups through 0,004 mm and mark paint from smaller to bigger: blue, green, red. The piston, a finger and a rod installed in one cylinder of the engine have to be one dimensional group.
Interface of a piston finger and the piston check, implanting the finger which is previously oiled engine into a piston lug opening. It is necessary for the correct interface that the piston finger entered an opening from pressing of a thumb of a hand (fig. Check of correctness of selection of a piston finger of the engine of fashion. 2106) also did not drop out of a lug (fig. Check of landing of a piston finger of the engine of fashion. 2106), if to keep the piston with a piston finger in vertical position.
The finger having of a lug to replace with another, the following category. If in the piston a finger of the third category then to replace the piston with a finger.
