The Chelsea 489 Series Power Take-Off, part number 489XFAHX-V5RY or 489XFAHXV5RY, is an air shift PTO designed for 8-bolt manual transmission openings on applications including Eaton Fuller, Eaton Endurant, Mack, and Tremec transmissions. The one-piece cast iron housing bolts directly to the 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 shaft power of 24 HP at 500 RPM or 48 HP at 1,000 RPM. Output is a rotatable DIN 5462 pump mount. Strong tapered bearings replace needle bearings for greater load capacity. Available from Pro Gear and Transmission. Call us to confirm proper fit for your application.
