The Chelsea 880 Series Power Take-Off, part number 880XBAKP-A3XV or 880XBAKPA3XV, is an 8-bolt, lever mechanical shift PTO rated up to 500 lb-ft (678 Nm) intermittent torque. The output shaft is a 1-1/2"-10 spline with a 1410 companion flange, delivering 48 HP at 500 RPM and 95 HP at 1000 RPM. Compatible with Volvo/Mack, Allison, Eaton/Fuller, and other transmission families that use an 8-bolt aperture. The cast iron housing features a removable shift cover for straightforward backlash adjustment, and the dual-pump output configuration allows a hydraulic pump to be mounted on each end. Typical applications include fire trucks, bulk haulers, oil field equipment, large recovery trucks, and aerial units. A genuine Chelsea part, available from Pro Gear and Transmission. Call us to confirm proper fitment for your specific transmission.
The Chelsea 880 Series is suited for heavy-duty, high-torque applications across oil and gas, aerial, mining, on-highway, and other mobile equipment markets. Typical vehicle applications include bulk haulers, fire trucks, oil field equipment, aerial units, winch-equipped trucks, and large recovery vehicles. The 880 Series features constant mesh input gears for high and low speed operation, tapered cone bearings for load capacity, and a cast iron housing. The removable shift cover allows backlash adjustment without removing the PTO from the transmission. Applications requiring continuous operation are supported with a 30% de-rating.
