The prevention

Directing plugs of valves are executed at the same time with a head of cylinders. Repair work (расточка or polishing) is carried out only in a specialised workshop.

The basic sizes of the valve

1 – the sizes are specified in specifications

2 – a facet corner

3 – a line parallel to a head of the valve

4 – the minimum thickness of 0,8 mm

5 – diameter of a core

6 – to check up on a bend

Backlash check between the valve and the directing plug

1 – стрелочный the indicator

2 – a valve core


Накатка an internal surface of the directing plug of the valve


If directing plugs of valves have deterioration and deformation within norm for reduction of a backlash with a core of the valve and decrease in the expense of oil on an internal surface of plugs it is recommended to execute накатку (for what it is necessary to address in workshops).
