442KWBQX-W6XK Chelsea PTO Assembly

The Chelsea 442 Series Power Take-Off, part number 442KWBQX-W6XK or 442KWBQXW6XK, is a 6-bolt mounted PTO built for light-to-medium duty vocational trucks including tow trucks, dump trucks, and service trucks. This unit runs an air shift actuation, a 0.391:1 gear ratio, and delivers output through a 1-1/4" round standard shaft. Mounting is via standard mount with metric studs. The 442 Series uses a cast iron housing with tapered cone bearings on the output shaft, and this assembly carries no internal pressure lube requirement. The 360-degree rotatable output flange aids installation clearance in tight cab-to-axle configurations. Call us to confirm proper fit for your transmission application.
