The Chelsea 442 Series Power Take-Off Assembly, part number 442XUJWX-P5XK or 442XUJWXP5XK, is a 6-bolt standard mount unit with metric studs designed for light-to-medium duty vocational applications. This assembly runs a 0.391:1 gear ratio with air shift actuation and a 1-1/4" round standard output shaft. No pressure lube is required. The cast iron housing and tapered cone bearings on the output shaft are characteristic of the 442 Series, which covers tow trucks, dump trucks, service trucks, and small aerial equipment. The rotatable output flanges allow clearance adjustments without repositioning the entire unit. Call us to confirm proper fit for your transmission and application.
