The Chelsea 892 Series Power Take-Off, part number 892HBFJW-B5XV or 892HBFJWB5XV, is a hydraulic hot-shift PTO engineered specifically for Allison 4700 Series transmissions. The 892 Series uses a 10-bolt mounting configuration and positions the pump mounting flange at the rear of the transmission, giving improved clearance between the PTO and the frame rail. Output is through an SAE C flange and SAE C output shaft. The one-piece main shaft eliminates input splines between the PTO body and the output extension, and wet spline technology is built in to extend pump shaft life under demanding duty cycles. The clutch sits at the rear of the PTO housing so the gear section tucks tightly against the transmission. Series-rated intermittent torque exceeds 501 lb-ft with output power above 56 HP. Typical applications include aerial trucks, fire and rescue, refuse trucks, and truck cranes. Call us to confirm proper fit for your specific transmission configuration.
