The Chelsea 489 Series Power Take-Off Assembly, part number 489XRITX-W3RB or 489XRITXW3RB, mounts directly to an 8-bolt transmission opening on compatible manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing eliminates the need for an adapter plate, removing a potential leak path. The series delivers intermittent torque in the 201-300 lb-ft range, with shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. Output is through a rotatable SAE B 4-bolt flange with a 7/8" 13-tooth SAE B shaft. Tapered bearings replace needle bearings for greater load-bearing capability. Internal parts are common to the Chelsea 442 Series, making service straightforward. Call us to confirm proper fit for your application.
