3.3.6. Check of directing valves

At repair work on a head of cylinders with leaky valves it is not enough to process or replace valves and saddles. Besides it is necessary to check up deterioration of directing valves. Check for engines with the big run is especially important. The worn out directing do not guarantee the central landing of valves and lead to the big expense of oil. If deterioration is too great, directing valves it is necessary to replace (is carried out in a workshop).

PERFORMANCE ORDER
1. Remove the valve.
2. Clear directing the valve a cylindrical brush.
3. Enter the valve in directing from outside chambers of combustion and measure люфт moving the valve here and there. Люфт the valve it is necessary to measure in parallel corresponding коромыслу since in this direction the greatest deterioration is shown.
4. For check put a steel ruler. Practically there should be no backlash. Boundary value: 0,2 mm.
5. If there is a micrometer and нутрометр, it is possible to measure an actual backlash between directing and a valve core.
6. If necessary replace directing (it is carried out in a workshop).

The prevention

At all do not establish again directing the same diameter.
