3.3.15. Grinding in of valves

GENERAL INFORMATION

After high-quality grinding of the interfaced surfaces of the valve and its saddle their grinding in is not obligatory.

Valves have to get used only the fine-grained rubber sucker, shlifpasty with use, established on a plate of the valve. For an education exception on surfaces of flutes during grinding in it is necessary to rotate the valve alternately in both parties, often raising it.


Prevention

After grinding in carefully to remove the paste remains.


Check quality of grinding in it is possible on a contact spot. Tightness of valves is checked as follows. The valve is installed on the place (freely, without pressing) and in the combustion chamber fuel is filled in. Fuel should not proceed via the valve. Otherwise it is necessary to repeat grinding in.
