The Chelsea 442 Series Power Take-Off Assembly, part number 442XUEWX-A3SQ or 442XUEWXA3SQ, is a 6-bolt mount PTO built for light-to-medium duty vocational trucks including tow trucks, dump trucks, and service trucks. This unit runs a 0.391:1 gear ratio with air shift actuation, a 1-1/4" round standard output shaft, and standard mounting with metric studs. The housing draws no pressure lube, relying on the cast iron construction and tapered cone output shaft bearings that define the 442 Series. The 442 Series covers output power in the 46-55 HP range and intermittent torque up to 250 lb-ft, making it a practical fit across a wide range of PTO-driven equipment.
