The Chelsea 489 Series Power Take-Off Assembly, part number 489XUAHX-V3GA or 489XUAHXV3GA, mounts directly to 8-bolt manual transmission openings on Eaton Fuller, Volvo, Mack, and other compatible transmissions. The one-piece cast iron housing bolts on without an adapter plate, removing a potential leak path compared to flanged designs. Intermittent torque capacity for the 489 Series is 250 lb-ft (339 Nm); shaft power is rated at 24 HP (18 kW) at 500 RPM and 48 HP (36 kW) at 1000 RPM. Output is a 1-1/4" round shaft with key. This unit uses a wire/cable mechanical shift and shares internal parts with the Chelsea 442 Series. Call us to confirm proper fit for your application.
The Chelsea 489 Series is suited for utility trucks, dump trucks and trailers, snow and ice removal equipment, and fire and rescue vehicles. The integral cast iron housing provides the same torque capacity as the 442 Series while mounting directly to the 8-bolt transmission opening. Strong tapered bearings replace needle bearings for improved load-bearing capability. The 489 Series offers eleven internal speed ratios and twenty-seven output options, including Chelsea's 360-degree rotatable flange with a greaseable shaft to help reduce pump shaft spline fretting and corrosion.
