The Chelsea 660GHAHX-A3RK or 660GHAHXA3RK is a 660 Series Power Take-Off built for medium to heavy duty applications on most popular 6-bolt manual transmissions. The 660 Series carries an intermittent torque rating of up to 375 lb-ft and supports continuous operation with a 30% de-rating. Its cast iron housing and tapered cone bearings on the output shaft contribute to a long service life, while tapered bearings on the input shaft provide greater load-bearing capability than needle-bearing designs. Shift options include wire/cable and mechanical. Compatible transmission manufacturers include Eaton/Fuller, Volvo/Mack, and other makes.
