The Chelsea 863 Series Power Take-Off, part number 863XBABX-Y5XV or 863XBABXY5XV, is a forward-and-reverse driveline PTO built for heavy-duty mechanical winch work in oil field, logging, and mobile equipment applications. It mounts to transmissions with an 8-bolt opening, including Eaton Fuller and Mack/Volvo units, using a reversible 8-bolt mounting configuration. Output is through a 1410 Series companion flange. Intermittent torque capacity is rated up to 500 lb-ft (678 Nm); continuous operation is supported with a 30% de-rating. Shift is via lever (mechanical). The cast iron housing and heavy-duty ball bearings on the output shaft contribute to the series' durability in maximum-duty reversible applications.
