The Chelsea 442 Series PTO Assembly, part number 442ZWJGX-W4XD or 442ZWJGXW4XD, is a 6-bolt, air-shift power take-off built for light-to-medium duty vocational truck applications including dump trucks, tow trucks, and service trucks. This unit runs a 0.391:1 gear ratio and delivers power through a 1-1/4" round standard output shaft. Mounting uses the standard configuration with metric studs. Lubrication is splash-style with no pressure lube circuit required. The cast iron housing and tapered cone bearings on the output shaft contribute to long service life across demanding duty cycles. Greaseable output shafts and a 360-degree rotatable output flange add installation flexibility and extended maintenance intervals. A genuine Chelsea part sold by Pro Gear and Transmission.
