The Chelsea 489XCAHX-M5XE is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed for manual transmissions including Eaton Fuller, Eaton Endurant, Mack, and Tremec. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. Shift type is wire/cable mechanical. 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. Tapered bearings provide greater load-bearing capability than needle-bearing designs. Common internal parts with the Chelsea 442 Series simplify service. A genuine Chelsea part from Pro Gear and Transmission.
