Description
The Chelsea 489 Series Power Take-Off, part number 489XAITX-A3RF or 489XAITXA3RF, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Volvo/Mack, and Tremec units. The one-piece cast iron housing eliminates the adapter plate found on some PTO installations, reducing potential leak paths. This unit uses wire/cable mechanical shift and delivers up to 46-55 HP of output power, with shaft power ratings of 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 489 Series carries the same 250 lb-ft intermittent torque capacity as the 442 Series and features tapered bearings instead of needle bearings for greater load-bearing capability. Output shaft is 1-1/4″ round. Call us to confirm proper fit for your application.
