This boom cylinder seal kit is essential for maintaining the integrity of the hydraulic cylinder, preventing fluid leaks and contamination ingress. Manufactured to meet rigorous OEM standards, these seals offer superior resistance to wear and hydraulic fluid degradation compared to worn or damaged seals. Operators may observe external hydraulic fluid leaks around the cylinder rod, or a loss of lifting power and slower boom movement 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 boom cylinder seal kit is often external hydraulic fluid leakage from the cylinder rod. If ignored, this leakage will worsen, leading to a gradual loss of hydraulic pressure and slower, less responsive boom operation. Eventually, the cylinder may fail to hold its position under load, posing a risk to operational stability.
Carefully inspect the cylinder rod for any scoring or damage before installing new seals, as imperfections can quickly wear out the new seals. Avoid using sharp tools that could nick or cut the new seals during installation.
When replacing the boom cylinder seal kit, inspect the cylinder barrel for wear and check the hydraulic fluid for signs of contamination.
