2.2.16. The piston

Removal

PERFORMANCE ORDER

	1. For dismantling and repeated assemblage 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 aperture in a clip arch.
The prevention 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.

Check

The piston and piston finger

PERFORMANCE ORDER

1. Check up an external surface of the piston on absence of damages, development or non-uniform deterioration. If necessary, replace the piston.

2. Check up each piston ring on absence of damages and non-uniform deterioration. If necessary, replace piston rings.

3. Check up a piston finger, inserting it in a piston aperture. The piston finger should enter smoothly into the piston by pressing it a hand (at a room temperature).

Piston rings

PERFORMANCE ORDER

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

Backlash between a piston ring and a flute in the piston:
The first компрессионное a ring: 0,04–0,085 mm
The second компрессионное a ring: 0,04–0,085 mm
Maximum permissible backlash: 0,1 mm

2. Measure a backlash in the lock of piston rings, manually having inserted a piston ring in the engine cylinder. The piston bottom push a piston ring in the bottom part of the cylinder. Щупом measure a backlash in the lock of a piston ring.

Backlash in locks of piston rings:
The first компрессионное a ring: 0,15–0,30 mm
The second компрессионное a ring: 0,20–0,40 mm
Маслосъемное a ring: 0,20–0,70 mm
Maximum permissible backlash: 1,0 mm

Installation

PERFORMANCE ORDER

1. Establish распорную the 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 распорной the plug, press it then, pressing on perimetre, establish it in a piston flute.
	The prevention Do not use пассатижи for a release of piston rings at installation of the lateral directing.
	3. Similarly establish the low lateral directing.
4. Пассатижами for a release of piston rings establish компрессионное a ring №2.
	5. Пассатижами for a release of piston rings establish компрессионное a ring №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 through the piston in a rod, and a piston finger establish on the other hand the piston.
The prevention Directing pins define position 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 position in a clip.
10. Establish the piston in gathering on a clip thus directing a pin supports a rod in a piston finger.
11. Check up correctness of a relative positioning of the piston and a rod and, rotating a nut with накаткой, fix the numbered plug on a shaft.
12. Insert a shaft through an aperture 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 prevention The effort запрессовки should not exceed a piston finger 22500 Н.
	Depth запрессовки: 0,3–0,5 mm
