The Chelsea 442 Series Power Take-Off, part number 442ZUKHX-W6XD or 442ZUKHXW6XD, is a 6-bolt, air-shift PTO with a 0.391:1 gear ratio. The output is a 1-1/4" round standard shaft (XD designation), and mounting uses a standard 6-bolt pattern with metric studs. The unit runs without pressure lube (dry-sump configuration). Built on a cast iron housing with tapered cone bearings on the output shaft, the 442 Series is suited for light-to-medium duty vocational work including tow trucks, service trucks, and dump trucks. The output flange is rotatable for installation clearance. Pro Gear and Transmission sells this as a genuine Chelsea part. Call us to confirm proper fit for your transmission application.
