The Chelsea 863 Series Power Take-Off Assembly, part number 863XBAHX-Y4XV or 863XBAHXY4XV, is a heavy-duty forward-and-reverse PTO built for demanding driveline applications. It mounts to transmissions with 8-bolt openings, including Eaton Fuller and Mack units, using a reversible mounting configuration. The output is a 1410 Series companion flange, suited for direct driveline connection. Intermittent torque capacity reaches 500 lb-ft (678 Nm), and the unit supports continuous operation with a 30% de-rating applied. A cast iron housing and heavy-duty ball bearings on the output shaft contribute to the 863 Series' durability in oil field, logging, and mechanical winch service. Shift is accomplished through a lever mechanism. Call us to confirm proper fit for your transmission and application.
