The Chelsea 442 Series PTO Assembly, part number 442ZSFNX-W5RA or 442ZSFNXW5RA, is a 6-bolt mount unit built for light-to-medium duty vocational applications including dump trucks, service trucks, tow trucks, and aerial equipment. This assembly runs an air shift actuation, a 0.391:1 gear ratio, and delivers output through a 1-1/4" round standard shaft. Mounting uses the standard configuration with metric studs, and the unit operates without pressure lubrication. The cast iron housing and tapered cone bearings are characteristic of the 442 Series, contributing to its service durability. Call us to confirm proper fit for your transmission application.
