Oil nozzle part number S6710041 for DH300 and DX300 excavator spare parts

The grease nipple part number for DH300 and DX300 excavators is S6710041.

Grease nipples (also known as grease fittings or lubricating grease fittings) are crucial components on bulldozers used for applying grease. Their core function is to provide continuous lubrication to moving parts (such as pins, bearings, and hinge points), reducing friction loss and extending part life. Grease is injected into the friction surfaces of moving parts (such as the mating surfaces of bucket tooth pins and tooth seats) via a grease gun, forming a protective oil film. This directly relates to the bucket tooth pin maintenance needs mentioned earlier. It prevents mud and moisture from entering, avoiding component corrosion or seizing (especially in dusty and humid conditions).
