The Chelsea 489 Series Power Take-Off, part number 489XQAHX-W3RK or 489XQAHXW3RK, is an 8-bolt mechanical shift PTO designed for most manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, removing the need for an adapter plate and reducing potential leak paths. The 489 Series uses tapered bearings rather than needle bearings for improved load-bearing capability, and shares internal parts with the Chelsea 442 Series. Intermittent torque rating for the series runs 201 to 300 lb-ft. Shift is wire/cable mechanical. Call us to confirm proper fit for your specific transmission and application.
