Description
The Chelsea 489 Series Power Take-Off Assembly, part number 489GRAHX-W3XD or 489GRAHXW3XD, mounts directly to an 8-bolt transmission opening using a one-piece cast iron housing that eliminates the need for an adapter plate, reducing potential leak paths. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. This unit uses a wire/cable mechanical shift and is compatible with Eaton Fuller, Volvo/Mack, and other manual transmissions. The 1-1/4″ round output shaft accepts a key. Internal components are common to the Chelsea 442 Series, and the kit-style design simplifies servicing. Call us to confirm proper fit for your application.
