The Chelsea 442XQAHX-S5XK or 442XQAHXS5XK is a 442 Series Power Take-Off built on a 6-bolt mounting pattern, compatible with a wide range of current heavy-duty transmission applications. The 442 Series uses a cast iron housing with tapered cone bearings on the output shaft, a combination that supports intermittent torque in the 201-300 lb-ft range and continuous output between 46 and 55 HP. Shift is accomplished through wire/cable or mechanical means. The output shaft is a round shaft with a 1-1/4" key configuration. Common vocational uses for the 442 Series include dump trucks, tow trucks, service trucks, and aerial units. Call us to confirm proper fit for your specific transmission and application.
