The Chelsea 892 Series Power Take-Off, part number 892HCFJW-B5AZ or 892HCFJWB5AZ, is a hydraulic hot shift PTO engineered specifically for the Allison 4700 Series transmissions. The 892 Series mounts with a 10-bolt pattern and positions the pump output flange to the rear of the transmission, creating clearance where space is tightest between the transmission and the frame rail. An SAE C output flange and SAE C output shaft handle demanding intermittent torque demands exceeding 501 lb-ft. The one-piece main shaft eliminates input splines between the PTO body and output extension, and the wet spline output extends pump shaft life in high-cycle applications such as aerial trucks, fire and rescue apparatus, refuse trucks, and truck cranes. Call us to confirm proper fit for your specific application.
