Check
The piston and the piston pin
| PERFORMANCE ORDER | | 1. Check the outer surface of the piston for damage, develop or uneven wear. If necessary, replace the piston. | | 2. Check each piston ring for damage and uneven wear. If necessary, replace the piston rings. | | 3. Check the piston pin by inserting it into the hole of the piston. The piston pin must be a smooth entrance into the piston by pressing it by hand (at room temperature). |

Piston rings
| PERFORMANCE ORDER | | 1. Insert the new piston ring in the groove of the piston and probe measure the clearance between the piston ring and the wall of the groove. If the clearance exceeds the limit, replace the piston. The gap between the piston ring and the groove in the piston:
The first compression ring: 0,04-0,085 mm
The second compression ring: 0,04-0,085 mm
Maximum permissible backlash: 0,1 mm | | 2. Measure the end gap of the piston rings, piston ring is manually inserted into the engine cylinder. Piston crown push the piston ring into the bottom of the cylinder. Feeler gauge, measure the end gap of the piston ring. The gap piston ring:
The first compression ring: 0.15-0.30 mm
The second compression ring: 0.20-0.40 mm
Scraper ring: 0,20-0,70 mm
Maximum permissible backlash: 1,0 mm |

Setting
| PERFORMANCE ORDER | | 1. Install the spacer. | | 2. Install the upper side rail. To install the side rail, first place one end of the side guide wall between the piston ring groove and the spacer, click on it and then clicking on the perimeter, install it in the groove of the piston. |  |
A warning  Do not use pliers for a release of piston rings when installing side rail.
|  | 3. Likewise, set the low side guide. | | 4. pliers for a release of piston rings, set the compression ring ?��2. |  | 5. pliers for a release of piston rings, set the compression ring ?��1. | | 6. Apply a thin coat of engine oil to the piston and piston rings. |  | 7. Place the piston rings, as shown in the figure. | | 8. The special adaptation compress piston rings on the piston. | | 9. Install the guide pins through the piston to the connecting rod and piston pin set on the other side of the piston. |
A warning The guide pins define the position of the connecting rod in the piston. After you install the piston, connecting rod, piston pin, and for adjustment of the piston pin in the insertion guide pins also determine their position in the clip.
| | 10. Install the piston assembly to the clamp, and the guide pin support rod in the piston pin. | | 11. Check that the mutual position of the piston and connecting rod and turn the knurled nut, attach numbered sleeve on the shaft. | | 12. Insert the shaft through the hole in the arch of the clip. Push piston pin to connecting rod, while the sleeve on the shaft engages with the upper part of the clamp arch, wherein the guide pin has to fall from the piston. |
A warning The force pressing the piston pin must not exceed 22,500 N.
|  | Joining depth: 0.3-0.5 mm |
