ZBXLB00070 For Volvo Ec290 Arm Cylinder Seal Kit — Volvo EC290

This is an arm cylinder seal kit for Volvo EC290 excavators, designed to replace worn seals within the arm hydraulic cylinder. It is manufactured to meet Volvo's rigorous standards, ensuring a tight seal that prevents fluid loss and maintains consistent cylinder performance, unlike degraded seals that lead to sluggish operation. Operators may observe slow or jerky arm movements, external hydraulic fluid leaks around the cylinder rod, or a reduction in the arm's lifting and digging force when these seals begin to fail.

Failure Symptoms

The first noticeable symptom is often a slight external leak of hydraulic fluid from the arm cylinder rod, accompanied by a decrease in the arm's speed or power. If ignored, the leaks will worsen, leading to fluid loss, potential system contamination, and increasingly sluggish or erratic arm movements. Continued operation with failed seals risks significant damage to the cylinder and hydraulic system, impacting overall machine efficiency and safety.

Installation Tip

Clean the cylinder bore and rod meticulously before installing the new seals to prevent contamination and ensure a proper fit. Make sure each seal is seated correctly and oriented as per the service manual instructions.

Service Note

Inspect the hydraulic fluid for signs of contamination and check the condition of the arm cylinder rod for any damage that might affect the new seals.
