The Graco 255216 Kit, Replacement, Wrist Pin is a genuine OEM maintenance component designed to restore and maintain the smooth mechanical movement of Graco pump drive linkage systems. This kit specifically replaces worn wrist pin bearings that are essential for reducing friction and ensuring stable motion in high-pressure fluid handling equipment.
Engineered for industrial reliability, this kit supports long-term performance in demanding circulation and pumping environments where continuous operation causes natural wear on mechanical joints.
The Graco 255216 Kit, Replacement, Wrist Pin is a factory-original repair kit that contains the components required to replace wrist pin bearings within the drive linkage assembly of compatible Graco pumps. These bearings are critical contact points that enable smooth oscillation of the pump’s connecting rod system.
Over time, wrist pin bearings wear due to constant motion and load stress. This kit restores original factory tolerances, helping maintain pumping efficiency, reduce vibration, and prevent mechanical failure in the drive linkage system.
According to Graco service documentation, this kit is specifically intended for replacing wrist pin bearings in E-Flo® pump assemblies and is part of routine preventive maintenance schedules for industrial pumping systems.
