The Chelsea 489 Series Power Take-Off, part number 489XWAHX-W3RA or 489XWAHXW3RA, bolts directly to an 8-bolt transmission opening on most 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. Output is delivered through a 1-1/4" round shaft (with key), and the unit shifts via wire/cable mechanical actuation. Intermittent torque rating for the 489 Series is 250 lb-ft (339 Nm); shaft power runs 24 HP at 500 RPM and 48 HP at 1000 RPM. Strong tapered bearings replace needle bearings for greater load-bearing capability. Typical applications include utility trucks, dump trucks, snow and ice removal equipment, and fire and rescue vehicles. Call us to confirm the correct fit for your transmission and pump setup.
