The Chelsea 489 Series Power Take-Off Assembly, part number 489ZRDAX-A5RA or 489ZRDAXA5RA, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Mack, and Tremec -- no adapter plate required, which eliminates a common leak path. The one-piece cast iron housing delivers the same intermittent torque capacity as the 442 Series (250 lb-ft / 339 Nm), and the wire/cable mechanical shift type suits a wide range of cab configurations. Shaft power output is 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 1-1/4" round output shaft with key accommodates greaseable output options to reduce spline fretting and corrosion. Internal parts are common to the Chelsea 442 Series, keeping spare-parts inventory simple. Call us to confirm proper fit for your transmission and application.
