The Chelsea 489XFAHX-C5RD is an 8-bolt mechanical shift Power Take-Off from the Chelsea 489 Series, designed to mount directly to most manual transmissions including Eaton Fuller, Eaton Endurant, Mack, and Tremec without an adapter plate. The integral one-piece cast iron housing eliminates the adapter plate and reduces potential leak paths. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and delivers up to 48 HP at 1,000 RPM via a 1-1/4" round keyed output shaft. Tapered bearings replace needle bearings for greater load-bearing capability. Common applications for this series include utility trucks, dump trucks, snow and ice removal equipment, and fire and rescue vehicles.
