The Chelsea 442 Series Power Take-Off Assembly, part number 442GQAHX-A3XD or 442GQAHXA3XD, is a 6-bolt, standard-mount PTO with metric studs designed for light-to-medium duty vocational truck applications. It shifts via air and delivers a 0.391:1 gear ratio through a 1-1/4" round standard output shaft. The no-pressure-lube lubrication system (X designation) keeps the drivetrain simple. Tapered cone bearings on the output shaft and a cast iron housing contribute to the long service life this series is known for.
