442XXEWX-A3XK Chelsea PTO Assembly

The Chelsea 442 Series Power Take-Off Assembly, part number 442XXEWX-A3XK or 442XXEWXA3XK, is a 6-bolt transmission-mount PTO built around a cast iron housing and tapered cone bearings on the output shaft. This unit runs an air shift actuator, a 0.391:1 gear ratio, standard mount with metric studs, and a 1-1/4" round standard output shaft. The no-pressure-lube (splash) lubrication design keeps maintenance simple, while the low-profile shift cover aids installation in tight engine bays. The 442 Series fits a wide range of vocational applications, including dump trucks, service trucks, tow trucks, and aerial units. Call us to confirm proper fit for your transmission.
