The Chelsea 489 Series Power Take-Off Assembly, part number 489XWAHX-W5XD or 489XWAHXW5XD, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Volvo/Mack, and Tremec. The one-piece cast iron housing eliminates the adapter plate found on other designs, cutting down on potential leak paths and installation time. Intermittent torque capacity matches the 442 Series at 250 lb-ft (339 Nm); output power reaches 48 HP at 1,000 RPM. The 1-1/4" round output shaft with key accepts a range of pump configurations, and shift is handled via wire/cable mechanical linkage. Tapered output bearings replace the needle bearings used on earlier designs for improved load handling. Call us to confirm proper fit for your application.
