14512955 — Bucket Cylinder Seal Kit Voe14512955 For Volvo Excavator Ec330B Ec360B

This is a bucket cylinder seal kit, designed to replace all the critical seals within the hydraulic cylinder responsible for the excavator's bucket movement. Manufactured from high-grade, wear-resistant materials, it ensures a tight seal against hydraulic fluid pressure and contaminants, preventing leaks that occur with worn or damaged seals. Operators will typically observe external hydraulic fluid leaks around the cylinder rod, a loss of lifting or digging power, or slow and jerky cylinder operation when this seal kit fails.

Failure Symptoms

The first sign of a failed bucket cylinder seal kit is usually visible hydraulic fluid leakage from the cylinder rod seal or between cylinder stages. If ignored, the leakage will worsen, leading to a gradual loss of hydraulic pressure and reduced lifting or digging force. Continued operation risks internal cylinder damage and potential uncontrolled movement of the bucket.

Installation Tip

Thoroughly clean the cylinder bore and rod before installing new seals to prevent damage and ensure a proper seal. Never use sharp tools to pry seals into place, as this can easily nick or cut them, leading to immediate leakage.

Service Note

Inspect the hydraulic cylinder rod for scoring or pitting, and check the cylinder barrel for straightness when replacing the seal kit.
