The Chelsea 489 Series Power Take-Off Assembly, part number 489GQAHX-A5XD or 489GQAHXA5XD, is an 8-bolt PTO built 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. Output shaft is a 1-1/4" round with key. Shift is wire/cable mechanical. Intermittent torque capacity is 201-300 lb-ft (301-400 Nm) series-rated, with shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. Cross-references include S-17903 or S17903 and 2000XEA013SE.
