This boom cylinder seal kit is essential for maintaining the integrity of the hydraulic cylinder, preventing leaks and ensuring proper operation of the boom arm. Manufactured to OEM standards, these seals are designed for superior durability and resistance to wear and tear compared to compromised seals that allow fluid bypass. Operators might observe slow or jerky boom movements, external hydraulic fluid leaks around the cylinder, 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 first indication of a failing seal kit is often visible hydraulic fluid leakage around the boom cylinder rod. If left unaddressed, the leakage will increase, leading to a gradual loss of hydraulic pressure and slower, less responsive boom operation. Persistent leakage can deplete hydraulic fluid levels, potentially causing damage to the hydraulic pump and other system components.
Thoroughly clean the cylinder bore and piston rod before installing the new seals to prevent damage from debris. Ensure the seals are properly seated and lubricated with clean hydraulic fluid to avoid tearing during installation.
Inspect the cylinder bore for scoring or damage and check the hydraulic fluid level and condition when replacing the boom cylinder seal kit.
