Description
Chelsea 442 Series Power Take-Off Assembly 442ZUDAX-A3XK or 442ZUDAXA3XK is a 6-bolt mount PTO built for light-to-medium duty vocational applications including service trucks, dump trucks, and tow trucks. This unit runs an air shift actuation, a 0.391:1 gear ratio, and delivers power through a 1-1/4″ round standard output shaft. Mounting uses the standard configuration with metric studs. The output side runs without pressure lubrication, with greaseable output shafts maintaining long-term serviceability. The cast iron housing and tapered cone bearings on the output shaft are characteristic of the 442 Series design. Call us to confirm proper fit for your transmission application.
