Bucket cylinder seal kit for Terex

The 3623397M91 seal kit is designed for the bucket cylinder on Terex heavy machinery. This kit contains the internal components required to reseal the hydraulic cylinder, which is responsible for the movement of the bucket during excavation, loading, and leveling tasks. By replacing the internal seals, this kit addresses issues such as hydraulic fluid leaks and internal pressure loss that can affect the force and speed of the bucket operation.

This kit is compatible with various Terex excavators, loaders, and backhoes that utilize this specific cylinder configuration. It includes all necessary seals, O-rings, wipers, and backup rings to restore the cylinder to its intended operational state.

Hydraulic cylinders function as actuators that convert fluid pressure into linear force. Within these assemblies, seals create hermetic barriers that prevent fluid bypass between the piston chambers and between the rod and the cylinder barrel. Over time, internal seals may lose their sealing properties, leading to fluid migration or external leaks. Regular maintenance involving the replacement of these components helps maintain the pressure-holding capacity of the hydraulic system and prevents contaminants from entering the cylinder assembly.
