The Chelsea 442 Series Power Take-Off 442ZQAHX-A3XR or 442ZQAHXA3XR is a 6-bolt mount PTO with air shift engagement and a 0.391:1 gear ratio. The output is a 1-1/4" round standard shaft, and mounting uses a standard configuration with metric studs. This unit runs without pressure lubrication (no pressure lube design), with greaseable output shafts to maintain service intervals in the field. The 442 Series uses a cast iron housing and tapered cone bearings on the output shaft, a build spec shared across the series that supports light-to-medium duty vocational work on tow trucks, service trucks, dump trucks, and aerial trucks. A genuine Chelsea part from Pro Gear and Transmission. Call us to confirm proper fit for your application.
