The Chelsea 489 Series Power Take-Off, part number 489XSDAX-A5RF or 489XSDAXA5RF, is an air-shift PTO designed for 8-bolt manual transmission openings including Eaton Fuller, Mack, and Tremec. Its one-piece cast iron housing bolts directly to the 8-bolt transmission aperture, eliminating the need for an adapter plate and reducing potential leak paths. The 489 Series delivers an intermittent torque rating of 201-300 lb-ft and an output power range of 46-55 HP. The output shaft is a 1" 15-tooth SAE BB shaft on a rotatable SAE B 2-bolt flange. Shift is accomplished via air shift actuation. Call us to confirm proper fit for your application.
