The Chelsea 442 Series Power Take-Off Assembly, part number 442GQJHX-P4XY or 442GQJHXP4XY, is a 6-bolt standard mount PTO built for light-to-medium duty vocational trucks. This unit runs a 0.391:1 gear ratio with air shift activation and mounts via standard metric studs. The 1-1/4" round output shaft operates without a pressure lube system. Tapered cone bearings on the output shaft and a cast iron housing are characteristics of the 442 Series, supporting applications on service trucks, dump trucks, tow trucks, and small aerial units. The output flange is rotatable for clearance in tight installations, and the output shaft is greaseable for extended service intervals. Call us to confirm proper fit for your transmission.
