The Chelsea 442 Series Power Take-Off Assembly, part number 442GSJHX-A4XD or 442GSJHXA4XD, is a 6-bolt mounting PTO with air shift actuation and a 0.391:1 gear ratio. The output is a 1-1/4" round standard shaft, and the unit mounts via standard mount with metric studs. No pressure lube is required, keeping installation straightforward. The cast iron housing and tapered cone bearings on the output shaft are characteristic of the 442 Series, which covers light-to-medium duty applications including dump trucks, service trucks, tow trucks, and small aerial trucks.
