The Chelsea 442 Series Power Take-Off Assembly, part number 442XWESX-A5GF or 442XWESXA5GF, is a 6-bolt mount PTO built for light-to-medium duty vocational truck applications including dump trucks, tow trucks, and service trucks. This unit runs an air shift actuation, a 0.391:1 gear ratio, and a 1-1/4" round standard output shaft. Mounting uses a standard configuration with metric studs. The no-pressure-lube design keeps the lubrication system straightforward. The cast iron housing pairs with tapered cone bearings on the output shaft, which is a defining characteristic of the 442 Series. Output flanges are rotatable for clearance flexibility.
