Seal kit for National Crane 6000B

The 960639 seal kit provides a comprehensive collection of sealing components designed to restore the functionality of hydraulic systems within National Crane machinery. By replacing worn or damaged seals, this kit effectively prevents fluid leakage and maintains the necessary operating pressure within cylinders, valves, and pumps. Each component is engineered to ensure the system operates without loss of efficiency or contamination, which is necessary for the precise and safe movement of crane assemblies.

This kit is compatible with National Crane 6000B and 600B truck-mounted cranes. It includes various O-rings, piston seals, rod seals, backup rings, and wiper seals, each tailored to specific locations within the hydraulic circuit. These components are essential for maintaining the performance of the boom cylinders, outriggers, and the slewing system. Proper installation of these seals helps prevent internal and external leaks that can lead to power loss, erratic movement, or the inability to hold a load securely.

Seal kits serve as a maintenance solution for hydraulic systems, providing the specific geometries and materials required for various points of articulation and pressure containment. They are used during scheduled maintenance or when a specific component exhibits signs of seal failure, ensuring the hydraulic system remains sealed against environmental contaminants and internal pressure loss.
