Failure Symptoms

Early failure may manifest as a slight decrease in hydraulic system responsiveness or minor whining noises under load. Continued operation with a failing pump can lead to reduced hydraulic pressure and flow, impacting implement speed and lifting capacity. This can result in the inability to perform critical operational tasks.

Installation Tip

Thoroughly flush the hydraulic system before installation to remove any debris that could damage the new pump. Ensure the pump shaft is properly aligned with the drive coupling to prevent premature wear.

Service Note

Inspect hydraulic filters and fluid for signs of wear debris, and check hydraulic lines for any internal restrictions.
