The Chelsea 489GRAHX-A3RE or 489GRAHXA3RE is a Power Take-Off assembly from the Chelsea 489 Series, designed for manual transmissions with an 8-bolt PTO mounting aperture. The integral 8-bolt cast iron housing bolts directly to the transmission opening without an adapter plate, reducing potential leak paths and cutting installation time. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and suits transmissions such as Eaton Fuller, Mack, and Tremec. Tapered bearings handle output loads, and the 1-1/4" round keyed output shaft supports greaseable output options. Shift type is wire/cable mechanical. Call us to confirm proper fit for your specific transmission and application.
