The Chelsea 489 Series Power Take-Off, part number 489XFAHX-A3GK or 489XFAHXA3GK, is an 8-bolt mount PTO designed for manual transmissions including Eaton Fuller, Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the transmission's 8-bolt opening, eliminating the adapter plate and reducing potential leak paths. Intermittent torque capacity for the 489 Series is 250 lb-ft (339 Nm); for continuous-duty applications, derate the torque rating by 30% and verify against the application pages. Shaft power output reaches 48 HP (36 kW) at 1000 RPM. The wire/cable mechanical shift operates a 1-1/4" round output shaft with keyway. Internal components are shared with the Chelsea 442 Series, and the kit-style assembly simplifies field servicing. Available in No Pressure Lube (X) or Pressure Lube (P) configurations. Contact Pro Gear and Transmission to confirm the correct fit for your transmission.
