The Chelsea 489 Series Power Take-Off (PTO), part number 489ZQDAX-P5RB or 489ZQDAXP5RB, fits most manual transmissions with an 8-bolt PTO mounting aperture, including Eaton Fuller, Mack, and Tremec. 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. This unit delivers 201 to 300 lb-ft intermittent torque with wire/cable mechanical shift, and features a 1-1/4-inch round keyed output shaft. Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Tapered bearings replace needle bearings for greater load capacity.
