The Chelsea 863 Series Power Take-Off Assembly, part number 863XBDAX-Y4XV or 863XBDAXY4XV, is a forward-and-reverse driveline PTO built for maximum-duty mechanical applications. It mounts to transmissions with 8-bolt openings, covering manual units from manufacturers including Eaton Fuller, Mack, Allison, and Volvo. The output is a 1410 Series companion flange, and the unit shifts via lever (mechanical). Intermittent torque capacity reaches 500 lb-ft (678 Nm); continuous operation is rated at 30% de-rating from peak. The cast iron housing and heavy-duty ball bearings on the output shaft are characteristic of the 863 Series, which is built for oil field and logging applications where winch duty cycles are demanding.
