The Chelsea 489GQAHX-P3GH or 489GQAHXP3GH is a 489 Series Power Take-Off for manual transmissions, featuring an 8-bolt one-piece cast iron housing that bolts directly to the transmission opening without an adapter plate, eliminating a potential leak path. This unit uses a wire/cable mechanical shift and delivers an intermittent torque rating of 201-300 lb-ft (301-400 Nm). The output shaft is a 1-1/4" round shaft with keyway. The 489 Series fits most manual transmissions including Eaton Fuller, Mack, and Tremec. Tapered bearings replace needle bearings for greater load-bearing capability.
