This boom cylinder seal kit is essential for maintaining the integrity of the hydraulic system, preventing fluid leaks and contamination within the boom cylinder assembly. It is constructed from high-quality, durable materials that withstand high pressures and extreme operating conditions, unlike worn seals that degrade and fail. Operators may notice slow or jerky boom movements, external hydraulic fluid leaks around the cylinder, or a loss of lifting capacity when this seal kit is compromised.
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 boom cylinder rod or casing. This can progress to reduced cylinder responsiveness, such as slower extension or retraction, and a decrease in the machine's lifting power. If left unaddressed, significant fluid loss can lead to hydraulic system contamination and potential cylinder failure.
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 seal lips during installation.
When replacing the boom cylinder seals, it is advisable to inspect the hydraulic fluid for contamination and check the condition of the cylinder rod for scoring or wear.
