The Chelsea 823 Series Power Take-Off, part number 823XGAHX-A4XV or 823XGAHXA4XV, 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 Allison, Eaton/Fuller, Volvo/Mack, and other manufacturers. The lever and mechanical shift design delivers up to 500 lb-ft (678 Nm) intermittent torque, with shaft power rated at 48 HP at 500 RPM and 95 HP at 1000 RPM. The output shaft is a 1-1/2 inch, 10-tooth spline with a 1410 series companion flange, supporting direct-mount pump configurations. A cast iron housing with tapered cone bearings on the output shaft provides greater load-bearing capability for sustained heavy-duty service. Call us to confirm proper fit for your transmission and application.
