Description
The Chelsea 442 Series Power Take-Off 442ZRDAX-A3GK or 442ZRDAXA3GK is a 6-bolt-mount PTO built around an air shift actuator and a 0.391:1 gear ratio. The output is a 1-1/4″ round standard shaft, and the unit mounts via Chelsea’s standard configuration with metric studs. A cast iron housing and tapered cone bearings on the output shaft give the 442 Series its class-leading torque capacity and long service life. No pressure lube is required. Greaseable output shafts and a 360-degree rotatable flange design allow flexible installation in tight chassis environments. Suited for service trucks, dump trucks, tow trucks, and light-to-medium duty vocational applications. Call us to confirm proper fit for your transmission.
