The Chelsea 489GRAHX-A5RC or 489GRAHXA5RC is a Power Take-Off unit from the Chelsea 489 Series, designed for manual transmissions with an 8-bolt PTO mounting aperture. The one-piece cast iron housing bolts directly to the transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. The 489 Series delivers intermittent torque capacity in the 201-300 lb-ft range and output power of 46-55 HP, with a 1-1/4" round keyed output shaft. Shift type for this series is wire/cable mechanical. Strong tapered bearings replace needle bearings for greater load-bearing capability. Compatible transmissions include Eaton Fuller, Mack, and Tremec. Call us to confirm proper fit for your application.
