442XFITX-A5XD Chelsea PTO Assembly

The Chelsea 442 Series Power Take-Off, part number 442XFITX-A5XD or 442XFITXA5XD, is a 6-bolt mount PTO assembly built for light-to-medium duty vocational applications including tow trucks, dump trucks, and service trucks. This unit runs a 0.391:1 gear ratio with air shift engagement, a standard mount with metric studs, and a 1-1/4" round standard output shaft. The no-pressure lube configuration (designator X) suits transmissions without a pressurized lube feed. Tapered cone bearings on the output shaft and a cast iron housing contribute to the 442 Series' torque capacity and service life. Call us to confirm proper fit for your transmission application.
