Horizontal cylinder seal kit for American Crane 7460

The 305265 seal kit contains the components required to reseal horizontal cylinders on the American Crane 7460 crawler crane. These seals prevent hydraulic fluid bypass between cylinder chambers and stop external leakage from the cylinder assembly. By maintaining the integrity of the hydraulic seal, these components allow the cylinder to hold pressure and perform controlled movements during crane operation.

This kit is compatible with the horizontal cylinders found on the American Crane 7460 crane, specifically for units with serial number 8002A023 31F. The kit includes various profiles such as O-rings, piston seals, rod seals, and wipers designed to match the specific dimensions and tolerances of the cylinder housing and rod. Proper installation ensures the hydraulic system functions within its design parameters.

Hydraulic cylinder seals serve to contain pressurized fluid within the actuator, which is necessary for the machine to generate force. When these seals degrade, the cylinder may experience internal bypass, leading to reduced lifting capacity or drifting, or external leakage, which results in fluid loss and potential contamination of the machine environment.
