Failure Symptoms

A failing main hydraulic pump will first manifest as a noticeable decrease in the speed and power of all hydraulic operations, especially when multiple functions are used simultaneously. If the issue is not addressed, the pump's output will continue to decline, leading to sluggish performance, potential overheating of the hydraulic fluid, and increased strain on the engine. Continued operation risks damage to other sensitive hydraulic components due to inadequate flow or pressure.

Installation Tip

Always ensure the hydraulic fluid reservoir is filled to the correct level with the specified fluid before attempting to start the engine. Never operate the pump without sufficient lubrication, as this will cause immediate internal damage.

Service Note

It is highly recommended to replace the hydraulic filter element and inspect the hydraulic fluid for any signs of metal particles or contamination.
