4.4.22.2. Check of a head of the block of cylinders

Measurement of height of the acting part of the vortex camera by means of a ruler and the probe


Measurement of height of the acting part of the vortex camera by means of the indicator of hour type


PERFORMANCE ORDER
1. Examine a head of cylinders on existence of cracks or signs of other damages.
2. Examine facets and saddles of valves on existence of damages. At detection of strong damages valves or saddles need to be profrezerovat or replaced.
3. Examine the directing plugs of valves. If plugs are worn-out, they need to be chiseled and established valves with the increased diameter of a core. Check that cores of valves were not bent.
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. Establish a head of the block of cylinders by combustion chambers up on wooden whetstones.
6. 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 or the handle. Rotating the valve a sucker in different directions, grind in the valve, and it is periodically necessary to lift the valve for redistribution of pritirochny paste.
7. If rough pritirochny paste is used, you 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. You make grinding in before emergence of easy gray and opaque color.
8. Carefully remove traces of pritirochny paste, using the corresponding solvent.
9. Examine springs of valves and replace them if they are strongly deformed or worn-out.
10. Measure deformation of surfaces of a head of the block of cylinders and compare the received indications to technical requirements. In need of a surface of a head it is necessary to process in a specialized workshop.
11. Measure a vystupaniye of vortex cameras.
12. Measure height of a vystupaniye of plates of valves.
