The Chelsea 489ZHDAX-P5XY or 489ZHDAXP5XY is a Power Take-Off assembly from Chelsea's 489 Series, designed to mount directly to 8-bolt manual transmission openings on applications such as Eaton Fuller, Mack, and Tremec gearboxes. The one-piece cast iron housing eliminates the need for an adapter plate, reducing installation time and potential leak paths. This unit uses a wire/cable mechanical shift and features a 1-1/4" round keyed output shaft. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and delivers shaft power of 24 HP at 500 RPM or 48 HP at 1,000 RPM. Tapered bearings provide greater load capacity than needle-bearing designs. Call us to confirm proper fit for your specific transmission and application.
