The Chelsea 489GFAHX-A5XD or 489GFAHXA5XD is a 489 Series power take-off assembly designed for manual transmissions with an 8-bolt PTO mounting aperture, including Eaton Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the 8-bolt opening, eliminating the need for an adapter plate and reducing potential leak paths. Intermittent torque capacity for the 489 Series is 250 lb-ft (339 Nm); continuous ratings should be confirmed on Chelsea's application pages. Output shaft is a 1-1/4" round with key. Shift is wire/cable mechanical. Output power reaches 48 HP at 1,000 RPM. Internal parts are common to the Chelsea 442 Series, and greaseable output options help protect shaft splines from fretting and corrosion. Call us to confirm proper fit for your specific transmission.
