Rotary oil gauge hole

Maintenance of the Oil Measuring Hole

The oil measuring hole is frequently opened and closed, making it prone to damage and gas leakage. Therefore, its tightness should be regularly inspected. During inspection, apply a thin layer of paint to the edge of the hole, gently close the cover, and apply a certain amount of pressure by hand. If a clear and complete imprint is left on the gasket, it is considered acceptable. If the imprint is incomplete, it indicates that the cover is no longer tight, and the gasket should be replaced.
