Description
The Chelsea 442 Series Power Take-Off, part number 442ZUKHX-W6GB or 442ZUKHXW6GB, is a 6-bolt mount PTO built around a cast iron housing with tapered cone bearings on the output shaft. This unit runs an air shift actuator and a 0.391:1 gear ratio, with a 1-1/4″ round standard output shaft. Mounting uses the standard configuration with metric studs. The no-pressure-lube design is paired with a greaseable output shaft for routine maintenance at the wheel end. A low-profile shift cover keeps the assembly tight in the chassis. Suited for tow trucks, dump trucks, service trucks, and light aerial equipment, the 442 Series is a proven 6-bolt platform for light-to-medium duty vocational work.
