442XSBZX-H3XD Chelsea PTO Assembly

The Chelsea 442 Series Power Take-Off, part number 442XSBZX-H3XD or 442XSBZXH3XD, is a 6-bolt mount PTO built for light-to-medium duty vocational applications including tow trucks, dump trucks, and service trucks. This unit runs a 0.391:1 gear ratio with air shift actuation and delivers power through a 1-1/4" round standard output shaft. Mounting uses the standard configuration with metric studs. The housing carries no pressure lube requirement. Tapered cone bearings on the output shaft and a cast iron housing give the 442 Series its strong torque rating and service life. The 442 Series supports up to 250 lb-ft intermittent torque and output power in the 46-55 HP range - confirm your application before ordering, or call us to verify fit.
