Vane kit for Terex BT4792

The 935-00144 vane kit is a set of components used to service the hydraulic triple pump on the Terex BT4792 crane. This kit provides the internal sliding vanes required to restore the pump's ability to move fluid and maintain system pressure within the hydraulic circuit. By replacing worn vanes, the assembly can regain its volumetric efficiency and operational capacity.

This kit is specifically engineered for the triple pump configuration on the Terex BT4792 model. The components are manufactured to meet the internal tolerances required for the pump rotor and housing. Proper installation of these vanes ensures that the pump can effectively supply pressure to the various hydraulic circuits responsible for crane functions such as lifting, rotation, and boom extension.

Vane kits are used in hydraulic pumps that utilize sliding vanes within an eccentric rotor to create variable volume chambers. As the rotor turns, these vanes move to draw in and discharge hydraulic fluid. Over time, the movement of these components leads to natural wear, which can reduce the pump's ability to generate required pressure. Regular maintenance using this kit helps preserve the performance of the hydraulic system.
