Seal kit for Grove RT 890

The seal kit Z9372000458 serves as a comprehensive set of components for the outrigger extension cylinder in Grove machinery. This kit includes various seals such as piston seals, rod seals, wiper seals, and O-rings, which are installed within the hydraulic cylinder to maintain internal pressure and prevent fluid leakage. By creating a tight seal, these components ensure the outrigger extension cylinder operates effectively during the deployment and retraction of the outrigger beams, which are necessary for leveling and supporting the crane during lifting operations.

This specific kit is compatible with the Grove RT 890 rough-terrain crane. It is engineered to fit the dimensions and housing requirements of the outrigger extension cylinder assembly on this model. The kit provides the necessary items to address seal wear within the hydraulic system of the outrigger.

In hydraulic systems, seal kits are used to replace worn or damaged sealing elements that prevent bypass leakage between the cylinder piston and the bore, or between the rod and the cylinder head. Maintaining the integrity of these seals is important for the controlled movement of the outrigger and the overall stability of the crane during its operational cycles.
