The Chelsea 489GSAHX-A3GH or 489GSAHXA3GH is a 489 Series Power Take-Off (PTO) designed for 8-bolt manual transmission openings, including Eaton Fuller, Mack, and Tremec. 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. Shift type for this series is wire/cable mechanical. The 489 Series uses tapered bearings rather than needle bearings for greater load-bearing capability. Output shaft type is a 1-1/4" round shaft with keyway. Intermittent torque rating for the 489 Series ranges from 201 to 300 lb-ft. Call us to confirm proper fit for your application.
