3.1.3.8. Grinding in of saddles of valves
THE GENERAL DATA

At faultlessly processed saddles of valves and new valves grinding in of saddles of valves in a head of cylinders is unessential.

Valves can get used only with use of fine-grained grinding paste. For performance of necessary rotary motions on a valve plate the tool with a rubber sucker is established. Formation рисок on landing facets during grinding in is eliminated frequent подниманием and uniform поворачиванием the valve.


The prevention

Grinding paste after grinding in is necessary for removing carefully.


The kind of a working surface in the course of grinding in can be supervised also by means of fuel: insert the valve, fill the chamber of combustion with fuel – fuel should not follow from directing the valve. Otherwise repeat grinding in process.
