The Chelsea 489GFAHX-S5XK is a 489 Series Power Take-Off (PTO) designed for manual transmissions with an 8-bolt mounting aperture, including Eaton Fuller, Mack, and Tremec applications. The integral 8-bolt cast iron housing bolts directly to the transmission opening without an adapter plate, reducing potential leak paths and installation time. Shift type for this series is wire/cable mechanical. The 489 Series uses tapered bearings rather than needle bearings for greater load-bearing capability. Intermittent torque rating for the 489 Series is 201-300 lb-ft. Output is via a 1-1/4" round shaft with key. Call us to confirm proper fit for your specific transmission and application.
