Description
The Chelsea 442 Series Power Take-Off, part number 442XWBSX-W3XR or 442XWBSXW3XR, is a 6-bolt mount PTO built around a 0.391:1 gear ratio with air shift actuation. The output is a 1-1/4″ round standard shaft, and mounting uses a standard configuration with metric studs. This unit runs without a pressure lube system. The cast iron housing and tapered cone bearings on the output shaft are characteristic of the 442 Series, which is applied across tow trucks, dump trucks, service trucks, and aerial equipment. The low-profile shift cover and 360-degree rotatable output flange help with clearance in tight installations. Call us to confirm proper fit for your specific transmission and application.
