The Chelsea 489XCAHX-A3XY or 489XCAHXA3XY is a 489 Series Power Take-Off unit designed for manual transmissions with an 8-bolt PTO mounting aperture, including Eaton Fuller, Mack, and Tremec gearboxes. The one-piece cast iron housing bolts directly to the 8-bolt opening, eliminating the need for an adapter plate and reducing potential leak paths. Shift type is wire/cable mechanical. The series supports intermittent torque ratings from 201 to 300 lb-ft and output power from 46 to 55 HP. Strong tapered bearings replace needle bearings for improved load capacity. Call us to confirm proper fit for your transmission and application.
