105-7397 Bucket Cylinder Seal Kit — Cat 3054 315

This is a comprehensive seal kit designed to replace all the critical seals within a hydraulic cylinder, preventing fluid leaks and maintaining system pressure. Manufactured to meet OEM quality standards, it provides a reliable seal compared to worn or cracked original seals. Operators may notice external hydraulic fluid leaks around the cylinder, sluggish or jerky hydraulic operation, or a loss of lifting/actuating force if these seals fail.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The most immediate symptom of failing cylinder seals is visible hydraulic fluid leakage around the cylinder rod or barrel. This leakage can lead to a gradual loss of hydraulic system pressure, resulting in slower or erratic operation of the cylinder. If left unaddressed, significant fluid loss can compromise the entire hydraulic system's performance and potentially damage the cylinder bore.

Installation Tip

Carefully clean the cylinder bore and rod before installing new seals to prevent damage from debris. Avoid using sharp tools that could nick or cut the new seals during insertion.

Service Note

When replacing cylinder seals, inspect the cylinder rod for scoring or damage, and check the cylinder bore for wear or pitting.
