The Chelsea 489GFAHX-H5XD is an 8-bolt Power Take-Off unit 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 bolts straight to the 8-bolt transmission opening, eliminating the need for an adapter plate and 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 or 48 HP at 1,000 RPM. Wire/cable mechanical shift operation and a 1-1/4" round keyed output shaft are standard for this series. Common applications include utility trucks, dump trucks, and snow and ice removal equipment.
