The Chelsea 823 Series Power Take-Off Assembly, part number 823XBAHX-Y5XV or 823XBAHXY5XV, is an extra heavy-duty PTO built for high-torque applications including oil field equipment, logging machinery, pumper cleaner trucks, and mining operations. It mounts via an 8-bolt pattern and fits automatic and manual transmissions from Eaton/Fuller, Allison, Volvo/Mack, and other manufacturers. Shift is lever/mechanical. The output shaft is a 1-1/2" 10-tooth spline with a 1410 Series companion flange. Intermittent torque rating reaches 500 lb-ft (678 Nm) - check application pages for actual torque ratings specific to your installation. Shaft output power runs 48 HP at 500 RPM and 95 HP at 1000 RPM. The cast iron housing uses tapered cone bearings on the output shaft for greater load-bearing capability. Call us to confirm proper fit for your transmission and application.
The Chelsea 823 Series is purpose-built for demanding vocational applications. Its cast iron housing and tapered cone bearings on the output shaft deliver the load-bearing capability needed for oil field, forestry, and heavy pumping equipment. Direct mount pump outputs and compatibility with both air and lever shift configurations give this series broad fitment across major transmission families. Seven internal speed ratios are available across the 823 Series lineup. Sold by Pro Gear and Transmission.
