The Chelsea 489 Series Power Take-Off Assembly, part number 489QLLZX-D3XD or 489QLLZXD3XD, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Volvo/Mack, and Tremec applications. The integral one-piece cast iron housing eliminates the need for an adapter plate, reducing potential leak paths compared to bolt-on adapter designs. Intermittent torque capacity for this series is 201-300 lb-ft (301-400 Nm), with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 1-1/4" round output shaft is available with or without a keyway. Internal parts share commonality with the Chelsea 442 Series, making bench service straightforward.
