The Chelsea 442 Series Power Take-Off Assembly, part number 442ZWJUX-W5AF or 442ZWJUXW5AF, is a 6-bolt mount PTO built for light-to-medium duty truck applications including dump trucks, service trucks, and towing and recovery vehicles. This unit uses cable shift activation and delivers power through an SAE B 2 or 4-bolt flange with a 1" 15-tooth SAE BB shaft. Mounting uses a deep mount. The no-pressure-lube (dry sump) design keeps maintenance straightforward. The cast iron housing and tapered cone output shaft bearings are characteristic of the 442 Series, giving it class-competitive torque capacity for vocational truck duty.
