The Chelsea 880 Series Power Take-Off Assembly, part number 880XMDAX-A6XK or 880XMDAXA6XK, is an 8-bolt PTO built for heavy-duty, high-torque applications on manual transmissions from Eaton/Fuller, Volvo/Mack, Allison, and others. It shifts via lever mechanical control and delivers output through a 1-1/2"-10T spline with a 1410 Series companion flange. Intermittent torque capacity reaches 500 lb-ft (678 Nm); shaft power runs 48 HP at 500 RPM and 95 HP at 1,000 RPM. The removable shift cover simplifies backlash adjustment, and the dual-pump output design allows mounting a hydraulic pump on each end. Typical applications include fire trucks, bulk haulers, oil field equipment, aerial units, and large-capacity recovery trucks. Call us to confirm proper fit for your transmission.
