The Chelsea 863GBAHX-Y5XV or 863GBAHXY5XV is a heavy-duty Power Take-Off Assembly from the Chelsea 863 Series, built around an 8-bolt mounting configuration that covers a wide range of manual transmissions including Mack and Eaton Fuller applications. Output is driveline style through a 1410 Series companion flange. The unit is lever-shifted and engineered specifically for maximum-duty reversible operation, making it well-suited to heavy mechanical winch work in oil field and logging environments. Intermittent torque rating reaches 500 lb-ft (678 Nm); continuous operation is supported with a 30% de-rating applied. The cast iron housing and heavy-duty ball bearings on the output shaft contribute to the series' reputation for long service life in demanding cycles.
