  • Page 35: Torque - Standard Torque Data For Hydraulic Connections

    • Hydraulic connections require a minimum assembly torque in order to provide zero leakage at rated pressure with adequate fatigue resistance. Over-torquing of a hydraulic connection can also lead to leakage or failure. For some connections, NEW HOLLAND CONSTRUCTION requires a different torque value than is listed in the ISO and SAE standards.
