The Chelsea 660GHAHX-A3XD or 660GHAHXA3XD is a 660 Series Power Take-Off built for medium to heavy duty vocational applications. The 660 Series fits most popular 6-bolt manual transmissions and carries an intermittent torque capacity up to 375 lb-ft, making it a strong fit where applications exceed the output of a 442 Series PTO. The cast iron housing and tapered cone bearings on the output shaft contribute to long service life, while tapered bearings on the input shaft improve load-bearing capability over needle-bearing designs. Shift options include wire/cable and mechanical actuation. Output configurations across the 660 Series span 26 options, including a 360-degree rotatable flange for flexible pump placement.
