Hydraulic cylinder seal kit for Terex TX760B

The seal kit 5004400M91 provides a comprehensive set of sealing components for the boom cylinder in Terex machinery. Its primary function is to maintain a hermetic seal within the hydraulic cylinder, which prevents fluid leakage and ensures the system retains the pressure required to extend, retract, and lift the boom assembly. By replacing worn seals, this kit addresses issues such as internal bypass or external fluid loss that can affect the operational efficiency of the hydraulic circuit.

This kit is compatible with the Terex TX760B model. It contains various sealing elements such as piston seals, rod seals, wear rings, and wiper seals, all of which are engineered to fit the specific dimensions of the cylinder assembly. These components are designed to withstand the operational pressures and fluid compatibility requirements of the Terex hydraulic system.

In hydraulic systems, seal kits are used to maintain the separation between high-pressure and low-pressure zones within the cylinder. Proper sealing is necessary to prevent internal leakage across the piston, which can cause the boom to drift or lose lifting capacity. Additionally, rod seals and wipers prevent external leaks and keep contaminants out of the hydraulic fluid, which is necessary for the longevity of the cylinder bore and rod surface.
