This is a comprehensive seal kit specifically designed for the dipper arm and bucket cylinders, ensuring the integrity of the hydraulic system by preventing fluid leaks and contamination. Manufactured to high-durability standards, it offers superior resistance to wear and pressure compared to a worn or damaged kit where seals are cracked or flattened. Operators may notice external hydraulic fluid leaks around the cylinder rod, or a loss of cylinder holding pressure (e.g., boom drifting down) when this seal kit fails.
Always verify with serial number before ordering.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The first indication of a failing seal kit is often visible hydraulic fluid leakage around the cylinder rod or a gradual loss of cylinder position when under load. If not addressed, the leakage will worsen, potentially leading to a significant loss of hydraulic pressure and reduced machine performance. Continued operation with leaking seals risks contaminating the hydraulic system and causing accelerated wear on cylinder rods and internal components.
Carefully inspect the cylinder rod for any nicks or scratches before installing new seals, as imperfections can cause immediate leaks and premature seal failure. Ensure all new seals are properly lubricated with compatible hydraulic fluid before insertion to prevent tearing during installation.
While the cylinders are disassembled, inspect the piston, rod, and cylinder bore for wear or damage, and clean or replace the hydraulic filter element.
