The Chelsea 489 Series Power Take-Off 489DQMBX-56XY or 489DQMBX56XY mounts directly to 8-bolt manual transmission openings, including Eaton Fuller, Mack, and Tremec, using a one-piece cast iron housing that eliminates the adapter plate and reduces potential leak paths. The 489 Series uses wire/cable mechanical shift and delivers output power in the 46-55 HP range. Strong tapered bearings replace needle bearings for greater load-bearing capability. The 1-1/4" round keyed output shaft is a standard configuration in this series. Internal parts are common with the Chelsea 442 Series, making service straightforward.

Additional Information
The Chelsea 489 Series is designed for utility trucks, dump trucks, snow and ice removal equipment, fire and rescue vehicles, and aerial applications. The 489 Series PTO kit-style construction simplifies field service, and its internal components are shared with the Chelsea 442 Series, so technicians already familiar with that platform can work on it with common parts. Twenty-seven output options are available across the 489 Series, including Chelsea's 360-degree rotatable flange with greaseable shaft to reduce pump shaft spline fretting and corrosion. Eleven internal speed ratios and shift options are offered across the series.
