The Chelsea 660GSAHX-P3RF or 660GSAHXP3RF is a 660 Series Power Take-Off built for medium to heavy duty applications on most popular 6-bolt manual transmissions, including Eaton/Fuller and Volvo/Mack units. The cast iron housing and tapered cone bearings on the output shaft give the 660 Series a torque capacity of up to 375 lb-ft intermittent, with continuous operation supported at a 30% de-rating. The tapered input shaft bearings provide greater load bearing capability than needle bearing designs. The space-saving air shift cover maximizes clearance under the truck. Shift type is wire/cable or mechanical. Call us to confirm proper fit for your specific transmission and application.
