3.1.3.8. Grinding in of saddles of valves

GENERAL INFORMATION

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 plate of the valve the tool with a rubber sucker is established. Education рисок on landing facets during grinding in is eliminated with a frequent podnimaniye and a uniform povorachivaniye of the valve.

Prevention

After grinding in it is necessary to remove grinding paste carefully.

The type 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.
