The Chelsea 892CBFJW-B3CK is a hydraulic hot-shift Power Take-Off built for Allison 4700 Series transmissions. Part of the Chelsea 892 Series, it uses a 10-bolt mounting configuration and positions the pump output flange at the rear of the transmission, improving pump clearance between the transmission and frame rail. The SAE C output shaft and outlet flange connect directly to the pump, and Wet Spline Technology extends spline life under continuous-duty demand. The one-piece main shaft eliminates input splines between the PTO body and the output extension. The 892 Series is rated for 56+ HP output and intermittent torque above 501 lb-ft, making it suited for aerial trucks, fire and rescue apparatus, refuse trucks, and truck cranes.
