The Chelsea 489 Series Power Take-Off Assembly, part number 489GCITX-V3XD or 489GCITXV3XD, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Eaton Endurant, Mack, and Tremec. The one-piece cast iron housing eliminates the need for an adapter plate, removing a potential leak path common to bolted-on adapter designs. Intermittent torque capacity for the 489 Series matches the 442 Series at 250 lb-ft (339 Nm), with shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. This unit uses a wire/cable mechanical shift and carries a 1-1/4" round output shaft with key. Strong tapered bearings replace needle bearings for greater load-bearing capability. Call us to confirm proper fit for your transmission and application.
