3.2.2.15.2. The directing plugs of valves

GENERAL INFORMATION

Prevention

The directing plugs of valves are executed with a head of cylinders at the same time. Repair work (boring or grinding) are carried out only in a specialized workshop.


Main sizes of the valve

1 – the sizes are specified in specifications

2 – facet corner

3 – line parallel to a valve head

4 – the minimum thickness is 0,8 mm

5 – diameter of a core

6 – to check for a bend

Check of a gap between the valve and the directing plug

1 – arrow indicator

2 – valve core

Nakatka

Nakatka of the internal surface of the directing valve plug

 

If the directing plugs of valves have wear and deformation within norm, then for reduction of a gap with a core of the valve and decrease in a consumption of oil on the internal surface of plugs it is recommended to execute a nakatka (for what it is necessary to address in workshops).
