The Chelsea 442 Series Power Take-Off, part number 442ZSAHX-A3XK or 442ZSAHXA3XK, 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 an air shift with a 0.391:1 gear ratio and delivers power through a 1-1/4" round standard output shaft. Mounting uses standard geometry with metric studs, and no pressure lube system is required. The cast iron housing and tapered cone bearings on the output shaft give the 442 Series its class-competitive torque capacity. Output flanges are rotatable for installation clearance, and the output shaft is greaseable for extended service intervals. Call us to confirm proper fit for your transmission application.
