The Chelsea 892UAFJW-D5XS or 892UAFJWD5XS is a hydraulic hot-shift power take-off from the 892 Series, designed specifically for Allison 4700 Series transmissions. The 892 Series moves the PTO pump mounting flange to the rear of the transmission, improving pump clearance in tight frame-rail installations. It mounts via a 10-bolt pattern with an additional rear bracket for support, and uses a one-piece main shaft that eliminates input splines between the PTO and the output extension. The SAE C output flange uses wet spline technology to extend PTO and pump shaft service life under demanding duty cycles. Common applications include aerial trucks, fire and rescue trucks, refuse trucks, and truck cranes. A genuine Chelsea part from Pro Gear and Transmission.
