2.2.16. Piston


1. For dismantling and repeated assembly of the piston and a rod it is necessary to use special tools 09234-33001.
2. Establish universal support in a clip between a rod and the piston.
3. Insert a stripper through an opening in a clip arch.


Insert a clip with the piston, a rod and a stripper under ползун the press.

4. A stripper squeeze out a piston finger from the piston.


Piston and piston finger

1. Check an external surface of the piston on absence of damages, development or non-uniform wear. If necessary, replace the piston.
2. Check each piston ring on absence of damages and non-uniform wear. If necessary, replace piston rings.
3. Check a piston finger, inserting it into a piston opening. The piston finger should enter smoothly into the piston by pressing it a hand (at room temperature).

Piston rings

1. Insert a new piston ring into a flute of the piston and shchupy measure a gap between a piston ring and a flute wall. If the gap exceeds maximum permissible value, replace the piston.

Gap between a piston ring and a flute in the piston:
First kompressionny ring: 0,04–0,085 mm
Second kompressionny ring: 0,04–0,085 mm
Maximum permissible gap: 0,1 mm

2. Measure a gap in the lock of piston rings, having manually inserted a piston ring into the engine cylinder. The bottom of the piston push a piston ring in the lower part of the cylinder. By Shchup measure a gap in the lock of a piston ring.

Gap in locks of piston rings:
First kompressionny ring: 0,15–0,30 mm
Second kompressionny ring: 0,20–0,40 mm
Maslosjemnoye ring: 0,20–0,70 mm
Maximum permissible gap: 1,0 mm


1. Establish the rasporny plug.
2. Establish the top lateral directing. To establish lateral directing, at first place one end of a lateral flute of a piston ring directing between a wall and the rasporny plug, press it then, pressing on perimeter, establish it in a piston flute.


Do not use пассатижи for a release of piston rings at installation of the lateral directing.

3. Similarly establish the low lateral directing.
4. To Passatizhami for a release of piston rings establish a kompressionny ring No. 2.
5. To Passatizhami for a release of piston rings establish a kompressionny ring No. 1.
6. Apply a thin film engine oil on the piston and piston rings.
7. Arrange locks of piston rings, as is shown in drawing.
8. The special adaptation compress piston rings on the piston.
9. Establish directing pins via the piston in a rod, and a piston finger establish on the other side of the piston.


Directing pins define the provision of a rod in the piston. After installation of the piston, a rod, a piston finger and the adaptation for installation of a piston finger in inserts directing pins also define their situation in a clip.

10. Establish the piston assembled on a clip thus directing a pin supports a rod in a piston finger.
11. Check correctness of a relative positioning of the piston and a rod and, rotating a nut with a nakatka, fix the numbered plug on a shaft.
12. Insert a shaft through an opening in a clip arch. Press a piston finger into a rod while the plug on a shaft will not contact with the top part of an arch of the clip, thus directing pin should drop out of the piston.


The effort of a press fitting of a piston finger should not exceed 22500 N.

Depth of a press fitting: 0,3–0,5 mm
