The Chelsea 442 Series Power Take-Off Assembly, part number 442KSAHX-A3GZ or 442KSAHXA3GZ, is a 6-bolt mount PTO built for light-to-medium duty vocational truck applications including tow trucks, dump trucks, and service trucks. This unit runs an air shift configuration with a 0.391:1 gear ratio and delivers power through a 1-1/4" round standard output shaft. Mounting follows the standard pattern with metric studs. The assembly carries no pressure lube requirement, relying on greaseable output shafts for maintenance. The cast iron housing and tapered cone bearings on the output shaft are characteristic of the 442 Series, which spans eleven internal speed ratios and thirty-six output options.
