The Sandvik 550508028 Hose Assembly is a key component in the hydraulic system of equipment like the Sandvik DD421. Hydraulic hoses are flexible conduits designed to carry fluid under high pressure between different parts of the hydraulic system, such as pumps, valves, and cylinders. They must withstand extreme pressures, temperatures, and harsh operating conditions common in underground mining. Proper selection and maintenance of components like the 550508028 Hose are vital to prevent system failures and ensure the smooth operation of drilling rigs and jumbos. A burst hose can lead to significant downtime and costly fluid leaks. Always use quality OEM alternative parts for replacement.

Fault: Intermittent loss of drilling/feed pressure, followed by a sudden spike or complete system shutdown.
Possible Cause: Failure of the Accumulator Diaphragm 56043103 (56043103) in the hydraulic circuit (often near the rock drill). The accumulator dampens pressure fluctuations and stores energy. If the diaphragm fails, the system loses its ability to stabilize pressure, leading to erratic operation and potential component damage, particularly to seals and hoses like the 550508028.
Solution:
Immediately shut down the drill and relieve all hydraulic pressure according to the operator manual.
Inspect the Hydraulic Accumulator. A leaking or ruptured Diaphragm 56043103 requires replacement.
Replace the faulty diaphragm with a high-quality OEM alternative. We supply the Epiroc/Sandvik Diaphragm 9106184722 (9106184722) and the Sandvik 56043103.
Recharge the accumulator with the correct gas (typically nitrogen) to the specified pre-charge pressure using proper charging tools.
Monitor the system after restart to ensure stable pressure. Also, check nearby Hoses and Seals (e.g., Seal Kit 3128345040) for secondary damage.
