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 saddle of the valve it is not enough. It is necessary to check up deterioration of directing valves. It is especially important to check engines with long term of operation.
Worn out directing valves do not provide центричности a saddle of the valve and conduct to the raised expense of oil. If deterioration is too great, replace directing the valve (work for repair shop).
| PERFORMANCE ORDER |
| 1. Remove the valve. |
| 2. Clean (1/2) directing the valve cylindrical brush (diameter about 20 mm). |
 |
3. Insert the valve from outside combustion chambers in directing and check up a backlash lateral moving of the gate backwards-forward. Thus it should not be felt an appreciable backlash. (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). | |
