The Chelsea 442XSFWX-A5RK is a 442 Series Power Take-Off built for 6-bolt transmission applications. The 442 Series uses a cast iron housing and tapered cone bearings on the output shaft, delivering an intermittent torque rating in the 201-300 lb-ft range and output power from 46 to 55 HP. The round output shaft (1-1/4" with keyway) is greaseable for extended service life, and the output flange is rotatable for improved clearance in tight installations. Shift is accomplished via wire/cable or mechanical connection. The 442 Series suits light-to-medium duty vocational work including dump trucks, tow trucks, and service trucks. Available from Pro Gear and Transmission.
