The Chelsea 489 Series Power Take-Off, part number 489KSITX-A3XK or 489KSITXA3XK, is an 8-bolt mechanical shift PTO built 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, eliminating the adapter plate and its associated leak path. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and output power of 46-55 HP. Strong tapered bearings replace needle bearings for greater load capacity. The 1-1/4" round key output shaft is shift-actuated via wire or cable. Common applications include utility trucks, dump trucks, snow and ice removal, and fire and rescue equipment. Call us to confirm proper fit for your specific transmission and truck configuration.
