This boom cylinder seal kit is designed to replace worn or damaged seals within the hydraulic boom cylinder, maintaining system pressure and preventing fluid leaks. Manufactured to high standards, it ensures a reliable seal comparable to original equipment, unlike a degraded seal that allows contamination. Operators may notice slow or jerky boom movements, external hydraulic fluid leaks around the cylinder, or a loss of lifting power when this 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 initial symptom of a failing seal kit is often a visible external hydraulic fluid leak from the boom cylinder rod. If left unaddressed, internal leakage will increase, leading to slower and less responsive boom operation. Continued use with compromised seals can result in significant hydraulic system contamination and potential damage to the cylinder rod and bore.
Carefully inspect the cylinder rod and bore for any nicks or scoring before installing the new seals, as imperfections can quickly damage them. Avoid using sharp tools to pry seals into place, which can cause tears.
Inspect the hydraulic fluid for contamination and consider replacing the hydraulic filter when servicing the boom cylinder.
