The Chelsea 489 Series Power Take-Off, part number 489XSEVX-A5RK or 489XSEVXA5RK, is an 8-bolt air shift PTO designed for most manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the 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. Tapered bearings replace needle bearings for greater load-bearing capability. Output shaft type is a 7/8 inch 13-tooth SAE B shaft on a rotatable SAE B 2 or 4-bolt flange. Call us to confirm proper fit for your application.
