The Chelsea 489 Series Power Take-Off, part number 489XSAHX-A3GQ or 489XSAHXA3GQ, is a mechanical-shift PTO built for 8-bolt manual transmission openings. The one-piece cast iron housing bolts directly to the transmission face, eliminating the adapter plate and reducing potential leak paths. The 489 Series fits most major manual transmissions including Eaton Fuller, Mack, and Tremec. Tapered bearings replace needle bearings for greater load capacity. The series supports intermittent torque in the 201-300 lb-ft range and output shaft options include a 1-1/4" round shaft with key. Call us to confirm proper fit for your specific transmission and application.
