Seal kit for Grove RT640S

The 8989163 seal kit provides the necessary components to restore the sealing integrity of hydraulic cylinders found in heavy machinery. By replacing worn seals, this kit addresses internal and external leakage, which helps maintain the pressure required for consistent operation of hydraulic systems. It is intended for use during the service and maintenance of specific cylinder assemblies.

This kit is compatible with the Grove RT640S rough-terrain crane. It is suitable for servicing various hydraulic cylinders, including those used for the boom, outriggers, or steering systems of the machine. The kit typically includes a selection of O-rings, lip seals, backup rings, rod wipers, and piston seals required to complete a cylinder overhaul. Proper installation of these components ensures that the hydraulic system maintains the necessary pressure to support safe and efficient crane operation.

Seal kits are used in hydraulic systems to create a barrier between moving parts and stationary housings. They prevent the escape of hydraulic fluid and stop external contaminants from entering the system. Maintaining these seals is standard practice for preventing cylinder drift and loss of power in hydraulic actuators.
