In the course of repair work on a head of the block of cylinders with not tight valves of processing or replacement of the valve and a valve saddle it is not enough. It is necessary to check wear of directing valves. It is especially important to check engines with long term of operation.
Worn-out directing valves do not provide a tsentrichnost of a saddle of the valve and conduct to the raised consumption of oil. If wear is too great, replace directing the valve (work for repair shop).
| PERFORMANCE ORDER |
| 1. Remove the valve. |
| 2. Clean directing the valve (1/2) a cylindrical brush (diameter about 20 mm). |
|
3. Insert the valve from the combustion chamber in directing and check a gap lateral moving of the gate backwards-forward. Thus it should not be felt an appreciable gap. (1–directing for the final valve, 2 – directing for the inlet valve, and – a spring lock ring.) |
| 4. If necessary replace directing valves (work for repair shop). | |
