The Chelsea 489 Series Power Take-Off, part number 489XWITX-W3XY, is an 8-bolt mechanical shift PTO designed for most manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing bolts directly to the transmission's 8-bolt aperture, eliminating the need for an adapter plate and reducing potential leak paths. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and output power of 46-55 HP, with a 1-1/4" round keyed output shaft. Strong tapered bearings replace needle bearings for greater load capacity. Internal parts are common to the Chelsea 442 Series. Available from Pro Gear and Transmission.
