The Chelsea 823XGAKX-A5XV or 823XGAKXA5XV is a heavy-duty power take-off assembly from the Chelsea 823 Series, engineered for high-torque applications including oil field equipment, logging, pumper/cleaner trucks, and mining. It mounts via an 8-bolt PTO aperture and is compatible with Eaton/Fuller, Volvo/Mack, Allison, and other transmission platforms. The lever/mechanical shift drives a 1-1/2 inch 10-tooth spline output shaft with a 1410 series companion flange. Shaft power ratings for the 823 Series run 48 HP at 500 RPM and 95 HP at 1000 RPM. The cast iron housing uses tapered cone bearings on the output shaft for high load-bearing capacity. Continuous operation is supported with a 30% de-rating.
