Hydraulic lift cylinder seal kit for Grove F T-87

The seal kit 7373100009 is designed for the lift cylinder assembly in Grove cranes. It provides the necessary barrier between the internal chambers of the cylinder, which allows the hydraulic system to maintain the pressure required for lifting and positioning loads. By preventing fluid bypass within the cylinder, these seals ensure that the hydraulic force is directed effectively to the cylinder rod for smooth operation.

This component is compatible with Grove F T-87, RT 700E, RT-650E, and T-750 models. The kit includes the specific seals required to restore the sealing surface between the piston and the cylinder bore, as well as the rod gland assembly. Proper installation of these seals is necessary to prevent external fluid leakage and to maintain the rated lifting capacity of the crane.

Hydraulic cylinder seals function by creating a tight interface that contains pressurized fluid while allowing for the reciprocating motion of the cylinder rod. Over time, these seals are subject to wear due to the constant cycling of the hydraulic system. Replacing them helps to restore the internal pressure balance and prevents the loss of hydraulic fluid, which is essential for the consistent performance of the lift system.
