Installation & Application Notes

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.

Failure Symptoms

A failing hydraulic cylinder may first present as a slight loss of lifting or pushing power. If ignored, the cylinder may begin to leak fluid externally or internally, leading to slower cycle times and increased heat in the hydraulic system. Eventually, the cylinder could seize or lose its ability to hold a load, compromising the equipment's operational capability.

Installation Tip

Ensure the cylinder rod is clean and free of debris before installation to prevent damage to new seals. Avoid over-tightening hydraulic fittings, as this can crack the connector or damage the seal.

Service Note

Inspect hydraulic lines, pumps, and fluid for contamination when replacing a hydraulic cylinder.
