The Chelsea 442 Series Power Take-Off Assembly, part number 442ZRITX-W3XK or 442ZRITXW3XK, is a 6-bolt mount PTO built for light-to-medium duty vocational truck applications. This unit runs a 0.391:1 gear ratio, uses air shift actuation, and delivers power through a 1-1/4" round standard output shaft. Mounting follows the standard configuration with metric studs. The housing requires no pressure lubrication. Cast iron construction and tapered cone bearings on the output shaft give the 442 Series its torque capacity and service life. Applications in the series include dump trucks, tow trucks, service trucks, and small aerial units. Call us to confirm proper fit for your specific transmission and chassis.
