442ZQITX-W6XK Chelsea 442 Series PTO Assembly

The Chelsea 442 Series PTO Assembly, part number 442ZQITX-W6XK or 442ZQITXW6XK, is a 6-bolt mount power take-off built on the 442 platform. It runs an air shift engagement, a 0.391:1 gear ratio, and a 1-1/4" round standard output shaft. Mounting uses standard metric studs. The unit requires no pressure lubrication, with greaseable output shafts serviced at the shaft rather than through a pressurized system. The cast iron housing carries tapered cone bearings on the output shaft. The 442 Series is suited to light-to-medium duty vocational trucks including dump trucks, tow trucks, and service trucks. Call us to confirm proper fit for your specific transmission application.
