The Chelsea 489 Series Power Take-Off Assembly, part number 489XFITX-A6XK or 489XFITXA6XK, is an 8-bolt PTO built for most manual transmissions including Eaton Fuller, Volvo/Mack, and Tremec platforms. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the adapter plate and its potential leak path. Intermittent torque capacity for this series is 201-300 lb-ft (301-400 Nm), with a continuous torque rating de-rated 30% from that figure (check application pages for your actual rating). The 1-1/4" round output shaft (with key) is driven by wire/cable mechanical shift. Shaft power is 24 HP at 500 RPM and 48 HP at 1,000 RPM. Strong tapered bearings replace needle bearings for improved load handling. Internal parts share commonality with the Chelsea 442 Series, making service straightforward. Call us to confirm proper fit for your transmission and application.
