The Chelsea 489 Series Power Take-Off, part number 489GQAHX-U3XK or 489GQAHXU3XK, 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. Intermittent torque for the 489 Series is 201-300 lb-ft (301-400 Nm); shaft power output reaches 24 HP at 500 RPM and 48 HP at 1,000 RPM. The output shaft is a 1-1/4" round configuration (with key option available). Shift is wire/cable mechanical. Internal parts are common with the Chelsea 442 Series, which simplifies service. Call us to confirm proper fit for your transmission and application.
