The Chelsea 442 Series Power Take-Off Assembly, part number 442XUBQX-W3XK or 442XUBQXW3XK, is a 6-bolt mount PTO designed for light-to-medium duty vocational applications including dump trucks, tow trucks, and service trucks. This unit carries a 0.391:1 gear ratio and uses air shift actuation. The output is a 1-1/4" round standard shaft, and mounting uses standard metric studs. The cast iron housing and tapered cone bearings on the output shaft are characteristic of the 442 Series, contributing to a strong torque rating and long service life. The output shaft runs without a pressure lube system. Cross-references include 1450-442XUBQXW3XK and CHL442XUBQXW3XK. Call us to confirm proper fit for your transmission application.
