The Chelsea 489XLITX-A3GK or 489XLITXA3GK is an 8-bolt power take-off assembly from Chelsea's 489 Series, designed to mount directly to the 8-bolt opening on most manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec units. The one-piece cast iron housing eliminates the adapter plate found on earlier designs, reducing potential leak paths. This unit uses a wire/cable mechanical shift and features a 1-1/4" round output shaft with key. Intermittent torque capacity for the 489 Series is 250 lb-ft; check application pages for your specific rating. Shaft power is 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are shared with the Chelsea 442 Series, which simplifies parts sourcing. Call us to confirm proper fit for your transmission application.
