The Chelsea 489XFAHX-M5RY or 489XFAHXM5RY is a Power Take-Off (PTO) from Chelsea's 489 Series, designed for 8-bolt manual transmission applications including Eaton Fuller, Mack, and Tremec gearboxes. 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 output shaft is a 1-1/4" round shaft with key. Intermittent torque capacity for the 489 Series ranges from 201 to 300 lb-ft. Internal parts are common to the Chelsea 442 Series.

The 489 Series features strong tapered bearings rather than needle bearings for greater load-bearing capability. Twenty-seven output options are available across the series, including Chelsea's 360-degree rotatable flange with greaseable shaft to reduce pump shaft spline fretting and corrosion.
