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 sign of a failing arm cylinder seal kit is typically visible hydraulic fluid leakage around the cylinder rod. If left unaddressed, this leakage will worsen, leading to a gradual loss of hydraulic pressure and reduced arm function. Continued operation with a leaking seal kit can lead to internal cylinder damage and contamination of the hydraulic system.
Ensure the cylinder rod is clean and free of any burrs or scoring before attempting to install the new seals. Avoid using sharp tools that could nick or damage the delicate sealing surfaces during installation.
Inspect the hydraulic fluid for contamination and consider changing the hydraulic filter when replacing arm cylinder seals.
