The Chelsea 892HAFJW-B5XV or 892HAFJWB5XV is a hydraulic hot-shift power take-off from the Chelsea 892 Series, engineered specifically for Allison 4700 Series transmissions. The 892 Series positions the PTO/pump mounting flange at the rear of the transmission to maximize pump clearance, and the one-piece main shaft eliminates the input splines between the PTO body and the output extension. Mounting is 10-bolt, the output shaft is SAE C flange type with wet spline technology for extended pump shaft life in demanding duty cycles. The clutch is located at the rear of the unit, letting the housing and gear section sit tight to the transmission. Typical applications include aerial trucks, fire and rescue, refuse trucks, and truck cranes. Call us to confirm proper fit for your transmission configuration.
