The Chelsea 489 Series Power Take-Off, part number 489ZFDAX-S5SQ or 489ZFDAXS5SQ, is a mechanical-shift PTO built for 8-bolt manual transmission openings. The 489 Series uses a one-piece cast iron housing that bolts directly to the transmission, eliminating the adapter plate and reducing potential leak paths compared to multi-piece designs. Internal parts are common to the Chelsea 442 Series, and the unit features tapered bearings rather than needle bearings for greater load-bearing capability. The 489 Series covers a wide range of manual transmissions, including Eaton Fuller, Eaton Endurant, Mack, and Tremec. Intermittent torque rating for the series runs 201-300 lb-ft.
