| 1. Check a plate of each valve for local corrosion, prozhog, cracks and the general wear. Check a valve core for wear and a bend. Check wear of an end face of a core of the valve. With any defects the valve is subject to replacement. |
| 2. Measure by a micrometer diameter of a core of the valve in several places on core length. Any essential distinction in the obtained data indicates wear of a core of the valve and obligatory replacement of the valve. |
|
|
3. Measure width of an edge of a plate of the valve. If width of an edge of a plate of the valve of less admissible limit, the valve is subject to replacement. |
| 4. If valves are in satisfactory condition, they have to be inserted into the places and are ground in. If plates of valves or a saddle are strongly worn-out, before their grinding in it is necessary to process mechanically or even to replace. |
| 5. Grinding in of valves is carried out as follows... |
| 5a. establish a head of the block of cylinders by combustion chambers up on wooden whetstones. |
| 5b. Grease with paste for grinding in of the place on a plate of the valve and a valve saddle. Install the valve on the place and on a plate of the valve establish a sucker with the holder. Rotating the valve a sucker in different directions, grind in the valve, and it is periodically necessary to lift the valve for redistribution притироч ache pastes. |
| 5 century. If rough pritirochny paste is used, to make grinding in before emergence of a uniform opaque surface on a saddle of the valve and the valve. Then erase the used composition of paste and repeat process of grinding in with fine paste. |
| 5 g. You make grinding in before emergence of easy gray opaque color. |
| 5. Carefully remove traces of pritirochny paste, using the corresponding solvent. |
