The Chelsea 442 Series Power Take-Off, part number 442XSITX-W3XK or 442XSITXW3XK, is a 6-bolt, air-shift PTO built for light-to-medium duty vocational trucks. The 0.391:1 gear ratio suits applications where output speed is a priority. The output is a 1-1/4" round standard shaft, and the unit mounts via standard mount with metric studs. A no-pressure-lube design keeps the drivetrain simple. The cast iron housing and tapered cone bearings on the output shaft are characteristic of the 442 Series, which carries an intermittent torque rating of up to 300 lb-ft for the series. Typical applications include tow trucks, dump trucks, and service trucks. This part is also cross-referenced as 442XTX-W3XK or 442XTXW3XK.
