NIPPLE - GREASE (Doosan DWKM4940284)

A worn grease nipple can allow contaminants into a bearing, accelerating wear and leading to premature component failure. This aftermarket replacement part cross-references Doosan part number DWKM4940284. The grease nipple serves as a fitting that provides a clean access point for applying lubricant to a bearing or pivot. Its plain mechanical function is to seal the lubrication port when not in use, preventing dirt ingress. A common failure consequence is that a damaged nipple will not hold grease, leaving the joint dry and prone to seizure. During routine service, a cracked nipple may leak grease, creating a mess and indicating the need for replacement. Verify the serial number or application, then call (562) 693-7748.
