The Chelsea 489 Series Power Take-Off Assembly, part number 489XQAHX-A3SQ or 489XQAHXA3SQ, 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 adapter plate found on earlier designs, removing a potential leak path. Intermittent torque capacity for the 489 Series is 201-300 lb-ft (301-400 Nm), with output power reaching 46-55 HP (31-40 kW). Shaft power measures 24 HP at 500 RPM and 48 HP at 1,000 RPM. This unit uses a wire/cable mechanical shift configuration and accepts a 1-1/4" round output shaft with keyway. Internal components are shared with the Chelsea 442 Series, keeping rebuild parts straightforward. Call us to confirm proper fit for your transmission and application.
