The Chelsea 823 Series Power Take-Off, part number 823XRAHP-A6XV or 823XRAHPA6XV, is an extra heavy-duty 8-bolt PTO built for high-torque applications including oil field equipment, logging, pumper/cleaner trucks, and mining. Shift type is lever/mechanical. The output shaft is a 1-1/2" 10-tooth spline with a 1410 Series companion flange for direct driveline hookup. Intermittent torque rating reaches 500 lb-ft (678 Nm) - verify the exact figure against Chelsea application pages for your specific configuration. Shaft power output is 48 HP at 500 RPM and 95 HP at 1,000 RPM. The 823 Series fits transmissions from Eaton/Fuller, Allison, Volvo/Mack, and other 8-bolt-mount platforms. Cast iron housing with tapered cone bearings on the output shaft supports heavy side loads common in blower and high-demand PTO duty cycles. Available from Pro Gear and Transmission. Call us to confirm proper fit for your transmission.
The Chelsea 823 Series uses a cast iron housing with tapered cone bearings on the output shaft for superior load-bearing capability in sustained high-torque applications. The 823 Series supports direct-mount pump outputs and is compatible with SAE C pump flange configurations across the broader 823 family. Seven internal speed ratios are available across the 823 Series lineup. Typical applications include oil field equipment, logging machinery, pumper/cleaner trucks, and mining equipment. Call Pro Gear and Transmission to confirm which ratio and shift configuration this specific unit carries for your application.
