The Chelsea 489 Series Power Take-Off Assembly, part number 489XQAHX-A6XK or 489XQAHXA6XK, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing eliminates the need for an adapter plate, removing a common leak path. Intermittent torque capacity for the 489 Series is 250 lb-ft (339 Nm). Output shaft is a 1-1/4" round with key. Wire/cable mechanical shift is standard on this unit. Shaft power output is 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common with the Chelsea 442 Series, making bench service straightforward. Call us to confirm proper fit for your transmission and application.
The Chelsea 489 Series is suited for utility trucks, snow and ice removal equipment, fire and rescue vehicles, and dump truck applications. Twenty-seven output options are available across the 489 Series, including a 360-degree rotatable flange with greaseable shaft to reduce pump shaft spline fretting and corrosion. Tapered bearings replace needle bearings for greater load-bearing capability. Eleven internal speed ratios are offered across the series. Internal components are shared with the Chelsea 442 Series, so rebuild kits and bench procedures transfer directly.
