442XUDUX-A5RB Chelsea 442 Series PTO Assembly

The Chelsea 442 Series Power Take-Off Assembly, part number 442XUDUX-A5RB or 442XUDUXA5RB, is a 6-bolt mounting PTO built for light-to-medium duty vocational applications including dump trucks, tow trucks, and service trucks. This unit carries a 0.391:1 gear ratio with air shift actuation and a 1-1/4" round standard output shaft. Mounting uses standard metric studs. The assembly runs without pressure lubrication (dry-lube configuration). A cast iron housing and tapered cone bearings on the output shaft contribute to the 442 Series' strong torque rating. The 360-degree rotatable output flange allows clearance adjustments during installation. Available from Pro Gear and Transmission - call us to confirm proper fit for your application.
