The Chelsea 489XWAHX-A3XY or 489XWAHXA3XY is a 489 Series Power Take-Off designed for manual transmissions with an 8-bolt PTO mounting aperture. The one-piece cast iron housing bolts directly to the transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. Shift type for the 489 Series is wire/cable mechanical. Intermittent torque capacity for the series runs 201-300 lb-ft (301-400 Nm), with output power in the 46-55 HP range. The 489 Series uses tapered bearings rather than needle bearings for greater load-bearing capability. Compatible transmissions include Eaton Fuller, Eaton Endurant, Mack, and Tremec.
