The Chelsea 880 Series Power Take-Off, part number 880XTAHX-Y3XV or 880XTAHXY3XV, is an 8-bolt PTO built for heavy-duty, high-torque intermittent service up to 500 lb-ft. The output shaft is a 1-1/2"-10 spline with a 1410 companion flange, and shift engagement is lever mechanical. Shaft power reaches 48 HP at 500 RPM and 95 HP at 1000 RPM. The cast iron housing supports dual-pump output, allowing a hydraulic pump to mount on each end. The removable shift cover simplifies backlash adjustment during installation. Typical applications include bulk haulers, fire trucks, oil field equipment, winch systems, and large recovery trucks. Call us to confirm proper fit for your transmission.
The Chelsea 880 Series is designed for continuous operation with a 30% de-rating applied. Tapered cone bearings handle the load demands of high-torque applications including oil field, aerial, mining, and on-highway service. The 880 Series is also available for the Eaton Endurant transmission. Consult the 880 Series Parts List (HY25-2880-M1_US) or the Chelsea Service Manual (HY25-6880-M1/US) for detailed service and parts information.
