LEFP00825 — For Volvo Excavator Ec55Blc Bucket Cylinder Seal Kit

This is a comprehensive seal kit designed to replace all critical seals within the bucket cylinder of a Volvo excavator, ensuring proper hydraulic pressure retention and preventing fluid leaks. Manufactured to meet stringent OEM quality standards, these seals offer superior resistance to wear, heat, and hydraulic fluid degradation compared to worn or damaged seals. Operators may observe hydraulic fluid leaks around the bucket cylinder, slow bucket operation, or a bucket that drifts down under load when these seals fail.

Failure Symptoms

The most common symptom of failing bucket cylinder seals is visible hydraulic fluid leakage around the cylinder rod or at the cylinder base. This leakage will worsen over time, leading to a loss of hydraulic pressure, resulting in slower or weaker bucket movements. If left unaddressed, significant fluid loss can lead to system contamination and potential damage to the cylinder rod and bore.

Installation Tip

Carefully clean the cylinder bore and rod before installing new seals to prevent damage from debris. Ensure all seals are properly seated and lubricated with system hydraulic fluid to prevent tearing during installation.

Service Note

Inspect the cylinder rod for scoring or damage, and check the hydraulic fluid level and condition before and after replacing the seal kit.
