The Chelsea 823 Series Power Take-Off, part number 823GRAHX-A3GS or 823GRAHXA3GS, is an extra heavy-duty PTO built for high-torque applications including oil field, logging, pumper cleaner trucks, and mining equipment. It mounts via an 8-bolt aperture and fits automatic and manual transmissions from Eaton/Fuller, Volvo/Mack, Allison, and other manufacturers. The lever/mechanical shift operates through a cast iron housing with tapered cone bearings on the output shaft for greater load-bearing capability. Output is delivered through a 1-1/2" 10-tooth spline with a 1410 Series companion flange. Shaft power is rated at 48 HP at 500 RPM and 95 HP at 1000 RPM, with intermittent torque up to 500 lb-ft (check application pages for actual torque ratings).
