Description
The Chelsea 880XRAHX-A5SS or 880XRAHXA5SS is an 880 Series 8-bolt power take-off assembly designed for heavy-duty, high-torque applications. It uses a lever mechanical shift and delivers up to 500 lb-ft intermittent torque. The output shaft is a 1-1/2″-10T spline with a 1410 companion flange, compatible with Volvo/Mack, Allison, and Eaton/Fuller transmissions, among others. Shaft power ratings for the 880 Series run 48 HP at 500 RPM and 95 HP at 1000 RPM. Typical applications across the 880 Series include fire trucks, bulk haulers, oil field equipment, aerial units, and large recovery trucks.
