The Chelsea 489GRAHX-A5GA or 489GRAHXA5GA is a Power Take-Off (PTO) assembly from Chelsea's 489 Series, designed for manual transmissions with an 8-bolt PTO mounting aperture. The one-piece cast iron housing bolts directly to the 8-bolt opening, eliminating the need for an adapter plate and reducing potential leak paths. This series covers compatible transmissions including Eaton Fuller, Mack, and Tremec. Shift type is wire/cable mechanical. 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. Internal components are common to the Chelsea 442 Series, and strong tapered bearings replace needle bearings for greater load-bearing capability. Call us to confirm proper fit for your specific transmission and application.
