The Chelsea 489 Series PTO Assembly, part number 489GHAHX-A5XQ or 489GHAHXA5XQ, mounts directly to 8-bolt manual transmission openings from Eaton Fuller, Volvo/Mack, Tremec, and others. The integral one-piece cast iron housing eliminates the adapter plate found on older designs, removing a common leak path. Wire/cable mechanical shift actuates the unit, and the 1-1/4" round output shaft (with key) delivers up to 250 lb-ft intermittent torque. Shaft power runs 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are shared with the 442 Series, and the kit-style design makes field servicing straightforward. Call us to confirm proper fit for your transmission and application.
