This boom cylinder seal kit is engineered to ensure the integrity of the boom cylinder's hydraulic system, preventing fluid leaks and maintaining consistent pressure for smooth operation. It is constructed from durable, high-performance materials designed to withstand the demanding conditions of heavy equipment use, offering superior sealing compared to worn components. Operators may notice external oil leaks from the boom cylinder, slow or erratic boom movements, or a gradual loss of lifting force when this seal kit begins to fail.
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 initial symptom of a failing boom cylinder seal kit is visible hydraulic fluid leaking from the cylinder rod. If left unaddressed, this leakage will worsen, leading to a loss of hydraulic pressure and slower, less responsive boom operation. Continued operation with leaking seals can cause internal cylinder damage and contamination of the hydraulic fluid, potentially affecting other system components.
Ensure the cylinder rod is clean and free from any burrs or scratches before installing the new seals to prevent immediate damage. Carefully insert the seals, ensuring they are seated correctly without twisting or deforming them.
Inspect the boom cylinder rod for wear or damage, and check the hydraulic fluid level and condition when replacing the seal kit.
