Description
The Chelsea 442 Series Power Take-Off Assembly, part number 442XUJBX-A5XK or 442XUJBXA5XK, is a 6-bolt mount 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 and engages via air shift, making it compatible with air-system-equipped trucks. The output is a 1-1/4″ round standard shaft, and the mounting configuration is standard mount with metric studs. The cast iron housing and tapered cone bearings on the output shaft are characteristic of the Chelsea 442 Series, which supports up to 48 HP at 1,000 RPM in shaft power output. The no-pressure-lube design simplifies installation where a pressurized lube circuit is not available. Call us to confirm proper fit for your application.
