The Chelsea 892CAFJW-B3CS or 892CAFJWB3CS 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, locating the pump output behind the transmission housing for improved clearance between the PTO and the frame rail. It mounts via a 10-bolt pattern with an additional rear support bracket. The output shaft is SAE C type with wet spline technology to extend pump and PTO shaft life in demanding cycles. The one-piece main shaft eliminates input splines between the PTO and output extension. Common applications include aerial trucks, fire and rescue, refuse trucks, and truck cranes. Call us to confirm proper fit for your specific Allison transmission configuration.
