14880359 — Boom Cylinder Seal Kit 14880359 For Volvo Ec55B Ec55C Ec55D Ec60C Ec60D Ec60E Ew145B Ew60C Ew60E

This is a boom cylinder seal kit, containing all necessary seals and O-rings to rebuild a Volvo excavator's boom hydraulic cylinder. It is crucial for maintaining hydraulic pressure within the cylinder, preventing leaks, and ensuring smooth, controlled boom movements, differing from worn seals by its ability to hold pressure and prevent fluid loss. Operators may notice hydraulic fluid leaking from the cylinder rod, slow or jerky boom operation, or the boom drifting down when the cylinder seals fail.

Failure Symptoms

Visible hydraulic fluid leakage around the boom cylinder rod is the most common initial symptom. This can progress to slow or erratic boom movements, and the boom may drift downwards when not actively being controlled. If left unaddressed, significant fluid loss can lead to system pressure loss and potential damage to the cylinder bore or piston.

Installation Tip

Carefully clean the cylinder bore and rod before installing the new seals to prevent damage and ensure a proper seal. Ensure all seals are oriented correctly according to the manufacturer's instructions.

Service Note

Inspect the cylinder rod for scoring or damage, and check the hydraulic fluid level and condition.
