The Chelsea 489XQAHX-A3XD or 489XQAHXA3XD is an 8-bolt power take-off assembly from Chelsea's 489 Series, designed for manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the adapter plate and reducing potential leak paths. Shift type is wire/cable mechanical. The 1-1/4" round output shaft (with key option) delivers up to 48 HP at 1,000 RPM, with an intermittent torque rating of 250 lb-ft for the 489 Series. Internal components are shared with the Chelsea 442 Series, keeping service parts accessible. Cross-references include 1450-489XQAHXA3XD, 2000XEA011SE, and 85100833.
