The Chelsea 489 Series Power Take-Off, part number 489GHAHX-A3FF or 489GHAHXA3FF, is an 8-bolt PTO designed for manual transmissions including Eaton Fuller, Volvo/Mack, and Tremec applications. The 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 is wire/cable mechanical. The 1-1/4" round output shaft with key accepts a range of output configurations, and the series offers 27 output options including a 360-degree rotatable flange. Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Tapered bearings replace needle bearings for improved load-bearing capability. Call us to confirm proper fit for your transmission and application.
