The Chelsea 442 Series Power Take-Off, part number 442ZUFNX-W5XK or 442ZUFNXW5XK, is a 6-bolt mount PTO built for light-to-medium duty vocational applications including dump trucks, tow trucks, and service trucks. This unit runs a 0.391:1 gear ratio with air shift actuation and a 1-1/4" round standard output shaft. Mounting uses standard metric studs. The no-pressure-lube configuration (lubricant code X) keeps installation straightforward. The cast iron housing and tapered cone bearings on the output shaft are characteristic of the 442 Series, contributing to a solid intermittent torque rating in the 250 lb-ft range for the series. Cross-references include S-17886 and 1450-442ZUFNXW5XK. Call us to confirm proper fit for your transmission application.
