The Chelsea 660GSAHX-A3RA or 660GSAHXA3RA is a 660 Series Power Take-Off built for medium to heavy duty truck applications. It mounts to most popular 6-bolt manual transmissions from Eaton/Fuller, Volvo/Mack, and other manufacturers. The 660 Series is characterized by a cast iron housing and tapered cone bearings on the output shaft, delivering an intermittent torque capacity up to 375 lb-ft. Tapered bearings on the input shaft provide greater load-bearing capability compared to needle-bearing designs.
