The Chelsea 442XQESX-A5RK is a 442 Series Power Take-Off built for 6-bolt transmission applications. The cast iron housing and tapered cone bearings on the output shaft deliver a series-rated intermittent torque range of 201-300 lb-ft and output power of 46-55 HP. The round shaft output uses a 1-1/4" key and is greaseable for extended service life. Shift is accomplished via wire/cable or mechanical actuation, and the output flange is 360-degree rotatable for improved clearance. Vocational applications for the 442 Series include dump trucks, tow trucks, service trucks, and aerial units.
