Failure Symptoms

The initial symptom of a failing boom cylinder seal kit is often a visible hydraulic fluid leak around the cylinder rod. If left unaddressed, the cylinder may lose its lifting capacity, causing sluggish or erratic boom movements. Continued operation can lead to significant hydraulic system contamination and potential damage to the cylinder bore.

Installation Tip

Carefully clean the cylinder bore and piston rod before installing the new seals to prevent damage and ensure a proper fit. Avoid using sharp tools that could nick or scratch the seal lips during installation.

Service Note

Inspect the hydraulic fluid for contamination and check the condition of the cylinder rod for scoring or wear when replacing the boom cylinder seals.
