The Chelsea 489 Series Power Take-Off, part number 489GFAHX-A5XY or 489GFAHXA5XY, is an 8-bolt mechanical shift PTO designed for most manual transmissions including Eaton Fuller, Eaton Endurant, Mack, and Tremec. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening without an adapter plate, eliminating a potential leak path. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and output power of 46-55 HP, with tapered bearings for greater load-bearing capability over needle-bearing designs. The shift type is wire/cable mechanical, and the output shaft is a 1-1/4" round shaft with key. Call us to confirm proper fit for your specific transmission and application.
