442XLAHX-A4XD Chelsea PTO Assembly

The Chelsea 442 Series Power Take-Off Assembly, part number 442XLAHX-A4XD or 442XLAHXA4XD, is a 6-bolt mount PTO built for light-to-medium duty vocational applications including dump trucks, service trucks, and towing and recovery vehicles. This unit runs an air shift actuator, a 0.391:1 gear ratio, and delivers power through a 1-1/4" round standard output shaft. Mounting uses a standard configuration with metric studs, and the unit operates without a pressure lube system. The cast iron housing pairs with tapered cone bearings on the output shaft for durability under intermittent loading. Call us to confirm proper fit for your transmission application.
