The Chelsea 660XSAHX-V3XX is a 660 Series Power Take-Off built for medium to heavy duty work. 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 load handling and long service life. Tapered bearings on the input shaft replace needle bearings for greater load capacity. The series carries an intermittent torque rating up to 375 lb-ft, with continuous operation available at a 30% de-rating. Output options span pump flanges and driveline configurations, and the space-saving air shift cover maximizes clearance under the vehicle. Typical vocational applications include dump trucks, aerial devices, service trucks, and snow and ice removal equipment.
