The Chelsea 489ZFAHX-A3RB or 489ZFAHXA3RB is a 489 Series Power Take-Off unit designed for manual transmissions with an 8-bolt PTO mounting aperture, including Eaton Fuller, Eaton Endurant, Mack, and Tremec gearboxes. The one-piece cast iron housing bolts directly to the 8-bolt opening, eliminating the need for a separate adapter plate and reducing potential leak paths. This unit uses wire/cable mechanical shift and delivers intermittent torque in the 201-300 lb-ft range. The round 1-1/4" keyed output shaft is a standard Chelsea 489 Series configuration. Internal parts are common to the Chelsea 442 Series, making service straightforward. Pro Gear and Transmission carries this genuine Chelsea part.
