The Chelsea 660XRAHX-A3XD or 660XRAHXA3XD is a 660 Series Power Take-Off assembly built for medium- to heavy-duty vocational applications. It mounts via a 6-bolt pattern and fits transmissions from Eaton/Fuller, Volvo/Mack, Hino, and other compatible manufacturers. Shift is accomplished through wire/cable mechanical actuation. The output shaft is a 1-1/4" round, and the unit delivers up to 375 lb-ft intermittent torque with output power rated at 56+ HP. Shaft power at the output runs 36 HP at 500 RPM, 71 HP at 1,000 RPM, and 107 HP at 1,500 RPM. The 660 Series design uses one-piece gears and tapered cone bearings on the output shaft for sustained torque capacity. Common applications include dump trucks, aerial devices, service trucks, and snow and ice equipment. Call us to confirm proper fit for your specific transmission.
