2.10. Check of valves
PERFORMANCE ORDER
1. Examine each valve on revealing of following defects:

      – Damages or deformation of a core of the valve;
      – Damages of a plate of the valve;
      – Damages or non-uniform deterioration of an end face of a core of the valve.
2. Check up width of a facet at an end face of a core of the valve. If necessary repair or replace the valve.

Width of a facet:
Inlet the valve: 1,0 mm
Final the valve: 1,0 mm

3. Measure length of each valve.
Length of the valve, mm

  Final the valve
The nominal
95,550
103,450
The minimum
95,350
103,250
4. By a micrometer in several places on height measure diameter of a core of the valve.

5,465–5,480
6,455–6,470
The minimum

   Final the valve
The nominal
5,430–5,450
6,450–6,465
The minimum
5,390
6,410

5. Нутромером in several places measure internal diameter of directing plugs of valves.

Internal diameter of directing plugs:
Engine A5D: 5,500–5,515 mm
Engine A3E: 6,500–6,515 mm

6. Calculate a backlash between the directing plug and a valve core. For this purpose subtract external diameter of a core of the valve from internal diameter of the corresponding directing plug of the valve.

Backlash:
Engine A5D:
Inlet the valve: 0,020–0,050 mm
Final the valve: 0,050–0,085 mm
Engine A3E:
Inlet the valve: 0,030–0,060 mm
Final the valve: 0,035–0,065 mm

7. If the backlash exceeds maximum permissible value, replace the valve and / or directing plug of the valve.
8. Measure height выступания each plug of the valve. If necessary replace directing plug of the valve.

Height выступания valve plugs:
Engine A5D:
Inlet the valve: 12,8–13,4 mm
Final the valve: 12,8–13,4 mm
Engine A3E:
Inlet the valve: 10,2–10,8 mm
Final the valve: 10,2–10,8 mm


The prevention

Directing plugs of inlet and final valves are various.
