The intake frame 151.37.048-4B (filter mesh) is an element of the oil intake system of the transfer case. It is installed from the bottom of the housing into the cover 151.37.333-1, while an oil-resistant o-ring 151.37.346 is used to ensure tightness. The hole into which the frame fits is closed with a lid 151.37.347.
According to the catalog, this part is part of the NMSh-25 pump assembly 151.37.072-2, which is responsible for supplying oil to the lubrication system and hydraulics of the transfer case. The frame mesh retains mechanical impurities, preventing contaminants from entering the pump and other components.
