Description
The Chelsea 442 Series Power Take-Off, part number 442KSAPX-W5XD or 442KSAPXW5XD, is a 6-bolt mount PTO built for light-to-medium duty vocational trucks. This unit runs an air shift mechanism, a 0.391:1 gear ratio, and delivers power through a 1-1/4″ round standard output shaft. Mounting uses standard 6-bolt geometry with metric studs. The no-pressure-lube (dry sump) configuration suits installations where a pressure lube circuit is not available. The cast iron housing and tapered cone bearings on the output shaft give the 442 Series its intermittent torque range of 201 to 300 lb-ft. Common applications include dump trucks, tow and recovery trucks, service trucks, and aerial units. Call us to confirm proper fit for your specific transmission.
