The Chelsea 442 Series Power Take-Off, part number 442XUAPX-A3XD or 442XUAPXA3XD, is a 6-bolt mount PTO built for light-to-medium duty vocational trucks including tow trucks, dump trucks, and service trucks. This assembly runs an air shift mechanism, a 0.391:1 gear ratio, and delivers power through a 1-1/4" round standard output shaft. Mounting uses standard metric studs. The unit operates without a pressure lube system (no-pressure lube configuration). The cast iron housing and tapered cone bearings are characteristic of the 442 Series, contributing to the series' intermittent torque rating of up to 250 lb-ft.
