The Chelsea 660KSAHX-H3XD or 660KSAHXH3XD is a 660 Series Power Take-Off designed to mount on most popular 6-bolt manual transmissions, including Eaton/Fuller and Volvo/Mack applications. The 660 Series carries an intermittent torque rating up to 375 lb-ft, making it a step up from the 442 Series for heavier hydraulic demands. The cast iron housing and tapered cone bearings on the output shaft contribute to the long service life this series is known for. Tapered bearings on the input shaft replace needle bearings for greater load-bearing capability. Shift type for this series is wire/cable or mechanical. Typical applications include dump trucks, aerial devices, service trucks, and snow and ice removal equipment. Call us to confirm proper fit for your specific transmission.
