The Chelsea 823 Series Power Take-Off Assembly, part number 823XMAKX-A5XV or 823XMAKXA5XV, is an extra heavy-duty PTO built for the most demanding high-torque applications. It mounts via an 8-bolt pattern and fits automatic and manual transmissions from Allison, Eaton/Fuller, Volvo/Mack, and other manufacturers. The mechanical lever shift operates through a cast iron housing with tapered cone bearings on the output shaft for maximum load-bearing capability. Output is delivered through a 1-1/2" 10-spline shaft with a 1410 Series companion flange. Shaft power reaches 95 HP at 1,000 RPM and 48 HP at 500 RPM. Intermittent torque is rated up to 500 lb-ft (check application pages for actual torque ratings). Common work includes oil field, logging, pumper/cleaner trucks, and mining equipment.
