2.10. Check of valves

PERFORMANCE ORDER
1. Examine each valve on detection of the following defects:

      – damages or deformation of a core of the valve;
      – damages of a plate of the valve;
      – damages or non-uniform wear of an end face of a core of the valve.
2. Check 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 valve: 1,0 mm
Final valve: 1,0 mm

3. Measure length of each valve.

103,450
The minimum

4. By a micrometer in several places on height measure diameter of a core of the valve.

6,450–6,465
The minimum

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

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

6. Calculate a gap 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.

Gap:
A5D engine:
Inlet valve: 0,020–0,050 mm
Final valve: 0,050–0,085 mm
A3E engine:
Inlet valve: 0,030–0,060 mm
Final valve: 0,035–0,065 mm

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

Height of a vystupaniye of the plug of the valve:
A5D engine:
Inlet valve: 12,8–13,4 mm
Final valve: 12,8–13,4 mm
A3E engine:
Inlet valve: 10,2–10,8 mm
Final valve: 10,2–10,8 mm


Prevention

Directing plugs of inlet and final valves are various.
