The Chelsea 489GRAHX-V3GY or 489GRAHXV3GY is a Power Take-Off assembly from Chelsea's 489 Series, engineered for 8-bolt manual transmission openings including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing bolts directly to the transmission without an adapter plate, cutting mounting time and reducing potential leak paths. This series delivers intermittent torque in the 201-300 lb-ft range and uses a wire/cable mechanical shift. The output shaft is a 1-1/4" round shaft with keyway. Internally, the 489 Series shares common parts with the Chelsea 442 Series and uses tapered bearings rather than needle bearings for greater load capacity. Pro Gear and Transmission sells genuine Chelsea PTOs - call us to confirm proper fit for your application.
