The Chelsea 489XHAHX-H3XY or 489XHAHXH3XY is a 489 Series Power Take-Off built for manual transmissions with an 8-bolt PTO mounting aperture, covering applications such as Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing bolts directly to the transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. This unit uses tapered bearings rather than needle bearings for greater load-bearing capability. No shift assembly (ordered without a shifter). Output shaft is a B8x32x36 DIN 5462 shaft on a DIN 5462 pump mount. The 489 Series carries an intermittent torque rating of 201-300 lb-ft.
