The Chelsea 489 Series Power Take-Off Assembly, part number 489XSEVX-A5RB or 489XSEVXA5RB, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Volvo, Mack, and others. The one-piece cast iron housing eliminates the need for an adapter plate, removing a common leak path. The output shaft is a 1-1/4" round with key option. Shift is wire/cable mechanical. Output power for this series runs 46-55 HP (31-40 kW), with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Intermittent torque is rated at 250 lb-ft (339 Nm); check the Chelsea application pages for your specific continuous torque rating. Internal parts are common to the Chelsea 442 Series.
