The Chelsea 660ZFDAX-P3XD is a 660 Series Power Take-Off built for medium to heavy duty 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 long service life. The series carries an intermittent torque capacity of up to 375 lb-ft, making it a step up from the Chelsea 442 Series when additional torque is required. A space-saving air shift cover maximizes clearance under the truck, and tapered bearings on the input shaft provide greater load-bearing capability over needle bearing designs. Common uses across the 660 Series include dump trucks, aerial devices, service trucks, and blower and product pump applications. Pro Gear and Transmission carries this genuine Chelsea part.
