This boom cylinder seal kit is designed to replace the worn or leaking seals within the main boom hydraulic cylinder, preventing hydraulic fluid loss and maintaining cylinder performance. Manufactured with high-quality sealing materials, it ensures a tight seal and smooth operation, unlike a damaged kit that would result in external leaks and internal pressure loss. Operators may observe hydraulic fluid leaking from the cylinder rod, slow or jerky boom movements, or a loss of lifting capacity 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 most common symptom of a failed boom cylinder seal kit is visible hydraulic fluid leakage around the cylinder rod or at the cylinder base. This leakage leads to a gradual loss of hydraulic pressure, resulting in slower or erratic boom operation and reduced lifting force. If left unaddressed, significant fluid loss can lead to pump cavitation and damage to other hydraulic system components.
Carefully clean the cylinder bore and rod before installing the new seals to prevent damage from dirt or debris. Ensure all seals are properly oriented and seated before reassembling the cylinder.
When replacing the boom cylinder seals, it is recommended to inspect the hydraulic fluid for contamination and consider flushing the system if necessary.
