The Chelsea 660XFAHX-A3RK is a 660 Series Power Take-Off designed to fit most popular manual 6-bolt transmissions in medium to heavy duty applications. The 660 Series uses a cast iron housing with tapered cone bearings on the output shaft for a high torque capacity, rated up to 375 lb-ft intermittent. Tapered bearings on the input shaft replace needle bearings for greater load-bearing capability. The series supports continuous operation with a 30% de-rating and accommodates wire/cable or mechanical shift types. Common applications include dump trucks, aerial devices, service trucks, blower and product pumps, and snow and ice removal equipment. Call us to confirm proper fit for your specific transmission and application.
