The Chelsea 442 Series Power Take-Off Assembly, part number 442KSAHX-A3SQ or 442KSAHXA3SQ, is a 6-bolt mount PTO built for light-to-medium duty vocational applications including tow trucks, dump trucks, and service trucks. This unit runs a 0.391:1 gear ratio with air shift actuation, a standard mount configuration with metric studs, and a 1-1/4" round output shaft. The no-pressure lube (dry sump) design simplifies installation where pressurized lube lines are impractical. The cast iron housing and tapered cone bearings on the output shaft are characteristic of the 442 Series, giving the unit a long service cycle in demanding daily-use environments.
