The Chelsea 489 Series Power Take-Off, part number 489XSAHX-A3GA or 489XSAHXA3GA, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Volvo/Mack, and Tremec applications. Its one-piece cast iron housing eliminates the need for an adapter plate, reducing potential leak paths. This unit uses a wire/cable mechanical shift and delivers up to 250 lb-ft intermittent torque, matching the torque capacity of the Chelsea 442 Series. Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 1-1/4" round output shaft accepts a key. Strong tapered bearings replace needle bearings for greater load-bearing capability. Internal parts are common to the 442 Series, making service straightforward. Call us to confirm proper fit for your specific transmission and application.
