The Chelsea 660XSAHX-V5XD or 660XSAHXV5XD is a 660 Series Power Take-Off designed for medium to heavy-duty applications on popular manual 6-bolt transmissions from Eaton/Fuller, Volvo/Mack, and other manufacturers. The 660 Series carries a torque capacity up to 375 lb-ft, making it a step up from the Chelsea 442 Series when additional torque is required. The cast iron housing and tapered cone bearings on the output shaft contribute to a long service life. Tapered bearings on the input shaft provide greater load-bearing capability compared to needle bearing designs. The series supports continuous operation with a 30% de-rating, and the air shift cover is designed to maximize clearance under the truck. 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 and application.
