442ZQAHX-A5RB Chelsea 442 Series PTO Assembly

The Chelsea 442 Series Power Take-Off Assembly, part number 442ZQAHX-A5RB or 442ZQAHXA5RB, is a 6-bolt mount PTO built around a cast iron housing with tapered cone bearings on the output shaft. This unit runs an air shift actuator, a 0.391:1 gear ratio, and a 1-1/4" round standard output shaft. Mounting uses standard mount with metric studs, and the unit requires no pressure lubrication. The 360-degree rotatable output flange gives clearance flexibility at installation, and the greaseable output shaft supports long service intervals. The 442 Series is suited for tow trucks, dump trucks, service trucks, and light aerial applications. Call us to confirm proper fit for your transmission and application.
