Description
The Chelsea 442 Series Power Take-Off, part number 442XXGYX-A3XD or 442XXGYXA3XD, is a 6-bolt mount PTO engineered for light-to-medium duty vocational truck applications. Key specs decoded from the part number: 0.391:1 gear ratio, air shift actuation, standard mount with metric studs, and a 1-1/4″ round standard output shaft. The unit runs without pressure lube (dry sump configuration). The cast iron housing and tapered cone output-shaft bearings are characteristic of the 442 Series and contribute to its service life in demanding cycles. The 360-degree rotatable output flange aids installation clearance. Typical applications include dump trucks, tow and recovery trucks, service trucks, and aerial equipment.
