The Chelsea 660XQAHX-V3GF or 660XQAHXV3GF is a 660 Series Power Take-Off built for medium to heavy duty vocational applications. The 660 Series mounts to most popular 6-bolt manual transmissions and features a cast iron housing with tapered cone bearings on the output shaft for a torque capacity up to 375 lb-ft intermittent. Tapered bearings on the input shaft provide greater load-bearing capability compared to needle bearing designs.
