The Chelsea 489 Series Power Take-Off, part number 489XFAHX-S3RK or 489XFAHXS3RK, is an 8-bolt PTO designed for most manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. Shift type is wire/cable mechanical. Output is rated at 46-55 HP intermittently, with an intermittent torque range of 201-300 lb-ft. The 489 Series uses tapered bearings for greater load capacity and shares internal parts with the Chelsea 442 Series. Call us to confirm proper fit for your application.
