The Chelsea 489 Series Power Take-Off Assembly, part number 489XRAHX-H3AZ or 489XRAHXH3AZ, mounts directly to an 8-bolt transmission opening on manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec without an adapter plate. The one-piece cast iron housing delivers the same 250 lb-ft intermittent torque capacity as the Chelsea 442 Series. Output is rated at 24 HP at 500 RPM and 48 HP at 1000 RPM through a 1-1/4" round output shaft with key. Wire/cable mechanical shift is standard on this unit. Tapered bearings replace needle bearings for greater load-bearing capability. Call us to confirm proper fit for your transmission.
