The Chelsea 660 Series Power Take-Off, part number 660XHAHX-V3GA or 660XHAHXV3GA, is built for medium to heavy-duty applications requiring a 6-bolt manual transmission mount. The 660 Series features a cast iron housing with tapered cone bearings on the output shaft, delivering up to 375 lb-ft of intermittent torque. Tapered bearings on the input shaft provide greater load-bearing capability than needle-bearing designs. The space-saving air shift cover maximizes 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 transmission and application.
