The Chelsea 892UAFJW-H5DA or 892UAFJWH5DA is a hydraulic hot-shift power take-off from the Chelsea 892 Series, designed specifically for Allison 4700 Series transmissions. The 892 Series relocates the pump mounting flange to the rear of the transmission, creating additional clearance in tight frame-rail installations. It mounts via a 10-bolt pattern with a secondary rear-bracket for added support, and delivers output through an SAE C flange and shaft. The one-piece main shaft eliminates inter-unit input splines, and the wet spline output extends pump shaft service life under continuous-duty demands. Typical applications include aerial trucks, fire and rescue equipment, refuse trucks, and truck cranes. Call us to confirm proper fit for your transmission configuration.
