K3V63 14T Drive Shaft Description
The YNF17873 K3V63 14T drive shaft is a key transmission component used in compatible K3V63 hydraulic piston pump assemblies. As an internal rotating component, the drive shaft transfers mechanical power from the drive system to the hydraulic pump rotating group, ensuring efficient torque transmission and stable pump operation.
Manufactured with precision machining technology and durable alloy steel material, this shaft provides accurate spline engagement, strong mechanical performance, and excellent resistance against wear and torque stress. The 14T spline structure helps maintain reliable power connection during continuous hydraulic operation.
The K3V63 14T drive shaft is suitable for hydraulic pump repair, rebuilding, and maintenance applications. It helps replace worn, damaged, or failed shaft components and supports the restoration of hydraulic pump performance in excavators and construction machinery.
