The Chelsea 489 Series Power Take-Off Assembly, part number 489XQITX-A3XK or 489XQITXA3XK, is an 8-bolt mechanical PTO designed for manual transmissions including Eaton Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the adapter plate and reducing potential leak paths. Wire/cable mechanical shift actuation comes standard, with an electric-over-air shift option available. Output is through a 1-1/4" round shaft with key, rated at 24 HP at 500 RPM and 48 HP at 1000 RPM. Intermittent torque capacity for the 489 Series is 250 lb-ft (339 Nm); consult the application pages for your specific torque rating. Internal components are common to the Chelsea 442 Series, simplifying parts inventory. Call us to confirm proper fit for your transmission.
