The Chelsea 892KDFJW-D5XV or 892KDFJWD5XV is a hydraulic hot-shift power take-off from the Chelsea 892 Series, designed specifically for Allison 4700 Series transmissions. The 892 Series moves the PTO and pump mounting flange to the rear of the transmission, improving pump clearance in tight frame-rail installations. The unit mounts via a 10-bolt pattern and delivers an SAE C flange output with wet spline technology, which extends the service life of both the PTO output shaft and the mating pump shaft under continuous-duty demands. Applications include aerial trucks, fire and rescue apparatus, truck cranes, and refuse vehicles. Call us to confirm proper fit for your application.

Additional Information
The 892 Series is a single-unit design, not a PTO paired with a separate extension. The main shaft is a one-piece construction, eliminating the input splines that would otherwise exist between a PTO body and an output extension. The clutch is positioned at the rear of the PTO housing, allowing the gear section to sit tightly against the transmission for maximum frame-rail clearance. The 892 Series can be configured for transmissions with or without a cooler, a retarder, or both. Typical service applications include aerial trucks, fire and rescue pumpers, truck cranes, refuse trucks, and snow and ice control vehicles.
