The Chelsea 489XLAHX-W3GF is an 8-bolt Power Take-Off from the Chelsea 489 Series, designed to mount directly to most manual transmissions including Eaton Fuller, Mack, and Tremec without an adapter plate. The one-piece cast iron housing eliminates the need for an intermediate adapter, reducing potential leak paths. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and produces up to 48 HP at 1,000 RPM via a 1-1/4" round keyed output shaft. Wire/cable mechanical shift actuation and strong tapered bearings set this series apart from needle-bearing alternatives. Internal parts are common with the Chelsea 442 Series, simplifying service. Available from Pro Gear and Transmission.
