This boom cylinder seal kit is essential for maintaining the integrity of the hydraulic cylinder, preventing leaks of hydraulic fluid and contamination from external elements. It is constructed from high-quality, durable materials that resist wear and extrusion, offering superior sealing performance over aged or damaged seals. Operators may observe hydraulic fluid leaks around the cylinder rod, a loss of lifting force, or slow, uncontrolled descent of the boom when these seals 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 first indication of failing boom cylinder seals is often visible hydraulic fluid leakage along the cylinder rod. If ignored, this leakage will worsen, leading to a gradual loss of hydraulic pressure and the inability of the boom to hold its position under load. The ultimate consequence is a compromised ability to lift and control the boom, potentially leading to unintended equipment movement.
Thoroughly clean the cylinder bore and rod before installing new seals to prevent any dirt or debris from causing damage. Ensure all new seals are properly seated and lubricated to prevent tearing during installation.
Inspect the hydraulic fluid and filter for contamination, and check the condition of the cylinder rod for any scoring or damage that could compromise the new seals.
