The Chelsea 489 Series Power Take-Off, part number 489XFITX-A3XK or 489XFITXA3XK, mounts directly to manual transmissions with an 8-bolt PTO opening, including Eaton Fuller, Mack, and Tremec gearboxes. The one-piece cast iron housing bolts straight to the transmission face, eliminating the adapter plate and its associated leak path. Shift is wire/cable mechanical. The 1-1/4" round output shaft is available with or without a keyway. Intermittent torque capacity for the 489 Series is 201-300 lb-ft (301-400 Nm), matching the 442 Series torque rating. Shaft power runs 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal components are shared with the 442 Series, keeping spare parts common across both units. Call us to confirm proper fit for your transmission and application.
The Chelsea 489 Series PTO is suited for utility trucks, dump trucks and trailers, snow and ice removal equipment, and fire and rescue applications. The series offers 27 output options and 11 internal speed ratios, including Chelsea's 360-degree rotatable flange with a greaseable shaft to reduce pump shaft spline fretting and corrosion. Tapered bearings replace needle bearings for greater load-bearing capability. The kit-style assembly design supports easier field service, and internal parts are shared with the 442 Series for common spare parts inventory.
