The Chelsea 489 Series PTO Assembly, part number 489XRAHX-V5AZ or 489XRAHXV5AZ, is a wire/cable mechanical shift unit built around an 8-bolt, one-piece cast iron housing that mounts directly to manual transmissions including Eaton Fuller, Mack, and Tremec without an adapter plate. The integral housing eliminates a potential leak path at the transmission face. Intermittent torque capacity for the 489 Series is 250 lb-ft (339 Nm); for continuous-duty applications, consult the application pages for actual de-rated torque ratings. Shaft power output is 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 1-1/4" round output shaft accepts a key. Tapered bearings replace the needle bearings found in earlier designs, adding load-bearing capability. Internal parts are common to the Chelsea 442 Series, simplifying parts sourcing and service. Call us to confirm proper fit for your specific transmission and application.
