The Chelsea 489 Series Power Take-Off Assembly, part number 489XRITX-W3GF or 489XRITXW3GF, mounts directly to 8-bolt transmission openings on Eaton Fuller, Mack, Tremec, and other compatible manual transmissions. The one-piece cast iron housing eliminates the adapter plate found on many competitive designs, reducing potential leak paths and simplifying installation. This unit delivers the same intermittent torque rating as the 442 Series - up to 250 lb-ft (339 Nm) - through tapered bearings rather than needle bearings for greater load-bearing capability. The 1-1/4" round output shaft (with keyway) and wire/cable mechanical shift type are defined in the 489XRITX-W3GF model designation. Output shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common to the Chelsea 442 Series, making service straightforward. Call us to confirm proper fit for your transmission and application.
