This is a boom cylinder seal kit designed to replace worn or leaking seals within the hydraulic boom cylinder assembly. It is manufactured to meet stringent OEM quality standards, providing a reliable seal that prevents hydraulic fluid loss and contamination ingress, unlike a failed kit which allows fluid bypass and dirt intrusion. Operators may observe a slow-moving or drifting boom, external fluid leaks around the cylinder rod, or a spongy feel when operating the boom functions.
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 initial sign of a failing seal kit is often a visible leak of hydraulic fluid from the cylinder rod or a slow drift of the boom when it should be holding position. If ignored, internal seal failure will lead to a significant loss of lifting capacity and potentially internal cylinder damage. Continued operation risks uncontrolled boom movement and contamination of the hydraulic system.
Carefully inspect the cylinder bore and rod for any scoring or imperfections that could damage the new seals before installation. Ensure all seal grooves are perfectly clean and free of debris.
Check the hydraulic fluid level and condition, and inspect the main hydraulic pump for any signs of wear when replacing the boom cylinder seal kit.
