The Chelsea 489XSAHX-A3XE is an 8-bolt mechanical shift Power Take-Off from the Chelsea 489 Series, designed to mount directly to the 8-bolt opening on most manual transmissions including Eaton Fuller, Mack, and Tremec without an adapter plate. The one-piece cast iron housing eliminates the adapter plate leak path common to other PTO designs. Output is through a 1-1/4" round keyed shaft. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and delivers up to 55 HP, with shift actuation via wire/cable mechanical control.
