Processing of facets of saddles of valves in a head cylinders/processing of valves

Facets of saddles of valves with wear tracks or a deposit can be processed while the most admissible amount of processing, adjustment corners and width of facets is maintained. Otherwise it is necessary to replace a head of cylinders. Saddles of valves can be replaced with usual means. The special device is necessary for processing. These works need to be performed in a specialized workshop. Identification of the engine see the Head Vvedeniye.

PERFORMANCE ORDER

For check of a working surface and width of a facet of the valve the facet of the valve should be covered with a thin layer of "Preussischblau" (Prussian blue) or "Bleiweiss" (white lead). To insert the valve and to press slightly on a saddle facet.

At the same time not to rotate the valve. If color is distributed unevenly, the facet of the valve should be processed further. At the same time it should not be exceeded the maximum or minimum sizes of width of a facet, see the size table of valves.

Vystupaniye of valves

After processing of facets of valves valve vystupaniye size - L-has to be checked. If value lies in limits - and - the size of a vystupaniye is normal if values lie in limits - b-, the size of a vystupaniye should be adjusted installation of a washer that value was reached - and-. If the maximum value - b-is exceeded, the head of cylinders should be replaced.
