3.3.7. Grinding in of a saddle of the valve

The processed saddle and the new valve have to be ground in to each other to provide the maximum consolidation.

Valves should be ground in only with small grinding paste. For necessary rotation on a plate of the valve the rubber sucker is established. Formation of grooves will be possible to avoid thanks to a frequent pripodnimaniye and further uniform rotation of the valve during grinding in process in different directions.


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

The working surface can check process of grinding in by the form or by means of fuel.

Insert the valve, fill the combustion chamber with gasoline, fuel should not follow from a valve guide, otherwise repeat grinding in.
