This is a boom cylinder seal kit, a vital component for maintaining the integrity of the excavator's boom hydraulic cylinder. It comprises multiple seals designed to prevent hydraulic fluid leakage and contamination ingress, ensuring smooth and powerful cylinder operation. A compromised seal kit can lead to slow boom movement, external leaks, and internal cylinder damage, ultimately affecting digging performance and potentially causing costly cylinder repairs.

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 sign of a failing boom cylinder seal kit is typically a visible hydraulic fluid leak from the cylinder rod seal or a noticeable decrease in boom lifting speed. If ignored, the leak will worsen, leading to reduced hydraulic pressure, potential internal cylinder damage, and compromised digging capabilities.
Thoroughly clean the cylinder bore and piston rod before installing new seals to prevent damage and ensure a proper seal. Avoid using sharp tools that could nick or scratch the new seals during installation.
Inspect the cylinder barrel for scoring and the piston rod for damage before installing the new seal kit.
