The Chelsea 489 Series Power Take-Off 489XFABX-A4XK or 489XFABXA4XK mounts directly to an 8-bolt transmission opening on compatible Eaton/Fuller, Volvo/Mack, and other manual transmissions. The one-piece cast iron housing eliminates the adapter plate found on earlier designs, reducing potential leak paths and cutting installation time. Intermittent torque capacity for the 489 Series is 250 lb-ft (339 Nm), matching the 442 Series rating. Shaft power output reaches 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 1-1/4" round output shaft with key accepts a wide range of driven accessories. Wire/cable mechanical shift is standard on this unit. Internal components are common to the 442 Series, simplifying parts stocking. Call us to confirm proper fit for your application.
