Backup ring for Terex TX760B

The backup ring 378545X1 serves as a mechanical support component within the hydraulic cylinder assembly of the Terex TX760B backhoe loader. It is specifically utilized in the sideshift dipper cylinder, which is manufactured by Pacoma. This component provides the necessary structural reinforcement to prevent the extrusion of pressure seals, such as o-rings, into the clearance gaps between mating surfaces during hydraulic operation.

By maintaining the correct shape and positioning of the primary seal, this ring helps prevent fluid leakage and pressure loss within the hydraulic system of the machine. It is engineered to withstand the compressive forces encountered during the operation of the dipper cylinder. Proper installation of this backup ring is necessary to support the integrity of the sealing system and ensure the hydraulic cylinder functions as intended within the backhoe loader architecture.
