FITTING - GREASE (Doosan DW9H3771)

A worn grease fitting can allow contaminants into the lubrication point, accelerating component wear. This aftermarket replacement part references the Doosan catalog number DW9H3771. The fitting serves as a conduit for introducing grease under pressure into a bearing or joint. Its plain mechanical function is to seal the lubrication port while permitting grease injection. A common failure consequence is that a clogged or damaged fitting blocks grease flow, leading to dry operation and eventual seizure. Keeping the fitting clear and properly seated helps maintain consistent lubrication delivery. Verify the serial number or application, then call (562) 693-7748.
