The Chelsea 489GHAHX-A5GZ or 489GHAHXA5GZ is a Power Take-Off assembly from the Chelsea 489 Series, built for 8-bolt manual transmission applications including Eaton Fuller, Mack, and Tremec. The integral one-piece cast iron housing bolts directly to the 8-bolt transmission opening, 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, and shares internal parts with the Chelsea 442 Series. Output is via a 1-1/4" round shaft with key. Call us to confirm proper fit for your specific transmission and application.
