The Chelsea 489 Series Power Take-Off, part number 489XHITX-A3GK or 489XHITXA3GK, 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. Output is through a 1-1/4" round shaft (with key option), rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Intermittent torque capacity for the 489 Series is 250 lb-ft. Shift is wire/cable mechanical. Internal components are common with the Chelsea 442 Series, keeping service parts accessible. Call us to confirm proper fit for your transmission and application.
