The Chelsea 442 Series Power Take-Off 442ZQAHX-A4XD or 442ZQAHXA4XD is a 6-bolt, air-shift PTO built for light-to-medium duty vocational applications. This unit carries a 0.391:1 gear ratio, mounts via standard mount with metric studs, and delivers output through a 1-1/4" round standard shaft. The no-pressure-lube configuration keeps maintenance straightforward. The cast iron housing and tapered cone bearings on the output shaft are characteristic of the 442 Series, which spans 36 output options and eleven internal speed ratios, making it a widely adaptable unit for service trucks, dump trucks, tow trucks, and small aerial platforms. The low-profile shift cover aids clearance in tight installations. Call us to confirm proper fit for your transmission application.
