Failure Symptoms

The initial symptom of a failing seal kit is often a visible external hydraulic fluid leak from the boom cylinder rod. If left unaddressed, internal leakage will increase, leading to slower and less responsive boom operation. Continued use with compromised seals can result in significant hydraulic system contamination and potential damage to the cylinder rod and bore.

Installation Tip

Carefully inspect the cylinder rod and bore for any nicks or scoring before installing the new seals, as imperfections can quickly damage them. Avoid using sharp tools to pry seals into place, which can cause tears.

Service Note

Inspect the hydraulic fluid for contamination and consider replacing the hydraulic filter when servicing the boom cylinder.
