Grease Hose 3917314

High-Durability Lubrication Line for Heavy-Duty Excavators

The Hyundai 3917314 is a high-durability grease hose designed for the demanding lubrication requirements of Hyundai's mid-to-large scale excavator fleet. This component is essential for maintaining the operational longevity of your machine by ensuring a consistent flow of high-pressure lubricant to critical swing and bucket linkage joints. Engineered to withstand the rigors of heavy-duty construction and mining environments, this genuine Hyundai hose prevents leaks and blockages, keeping your pivot points properly lubricated and protected from friction-induced wear.

1. Technical Specifications

Parameter	Detail
Part Number	3917314
Component Type	Grease Hose (Lubrication Line)
Primary Function	Delivers high-pressure lubricant to heavy-duty pivot points to maintain smooth operation and prevent metal-on-metal wear
Compatibility	Specifically engineered for large-frame excavators, including R275LC-9T, R305LC-9T, R335LC-7, R335LC-9T, and R375LC-7

2. Why Genuine Lubrication Parts Matter

In large-scale excavators, the forces applied to the arm and bucket linkage are immense. If these joints are not adequately lubricated, they quickly develop play, leading to costly mechanical failure. The 3917314 grease hose is manufactured with reinforced casing to handle the high pressures required to force fresh grease into joints packed with heavy soil and debris, ensuring your maintenance routine remains effective and efficient.

3. Maintenance & Installation Protocols

Diagnostic Indicators: Inspect the hose during every major service interval. Replace the hose if you notice any external cracking, weeping of grease along the body, or if the crimped ends show signs of corrosion.
Installation Advice: Ensure the hose is routed away from high-temperature areas (such as the engine exhaust) and moving components that could cause chafing. Tighten the fittings securely to prevent pressure loss.
Maintenance Tip: If you find it difficult to pump grease through a specific joint, verify that the hose itself is not internally clogged or crimped before servicing the zerk fitting or the joint pin.
