The Chelsea 660XQAHX-A3XQ is a 660 Series Power Take-Off built for medium to heavy duty applications on most popular 6-bolt manual transmissions. The cast iron housing and tapered cone bearings on the output shaft support the series' rated intermittent torque capacity of up to 375 lb-ft. Tapered bearings on the input shaft, rather than needle bearings, provide greater load-bearing capability. The 660 Series supports continuous operation with a 30% de-rating and is suited for demanding vocational work including dump trucks, aerial devices, service trucks, and snow and ice removal equipment.
