The Chelsea 489 Series Power Take-Off Assembly, part number 489GLAHX-A5RE or 489GLAHXA5RE, mounts directly to 8-bolt transmission openings on Eaton/Fuller, Volvo/Mack, and other compatible manual transmissions - no adapter plate required. The one-piece cast iron housing eliminates a common leak path versus two-piece designs. Intermittent torque capacity runs 201-300 lb-ft (301-400 Nm), matching the 442 Series rating. Output shaft is 1-1/4" round with key. Shaft power reaches 24 HP at 500 RPM and 48 HP at 1,000 RPM. Wire/cable mechanical shift type. Tapered output bearings replace needle bearings for increased load capacity. Call us to confirm proper fit for your transmission and application.
The 489 Series is suited for aerial, vocational, municipal, utility, dump truck, snow and ice removal, and fire and rescue applications. The series offers 27 output options including a 360-degree rotatable flange with greaseable shaft to reduce pump shaft spline fretting and corrosion, plus 11 internal speed ratios. Internal components are shared with the Chelsea 442 Series, keeping spare parts inventory straightforward for shops already running 442 Series units.
