The Chelsea 489GQAHX-A5XK or 489GQAHXA5XK is a 489 Series Power Take-Off unit built around a one-piece cast iron housing that bolts directly to an 8-bolt transmission opening on most manual transmissions, including Eaton Fuller, Mack, and Tremec. The integral housing eliminates the need for an adapter plate, reducing potential leak paths at installation. This unit delivers intermittent torque in the 201-300 lb-ft range and shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. The output shaft is a 1-1/4" round with key. Wire/cable mechanical shift is standard on this configuration. Tapered bearings replace needle bearings for improved load-bearing capability. Pro Gear and Transmission sells genuine Chelsea parts.
