The Chelsea 489 Series Power Take-Off Assembly, part number 489XUITX-S3XK or 489XUITXS3XK, bolts directly to an 8-bolt transmission opening on compatible manual transmissions including Eaton/Fuller and Volvo/Mack applications. The one-piece cast iron housing eliminates the adapter plate found on some competitive designs, removing a potential leak path. This unit uses air shift and delivers up to 250 lb-ft intermittent torque, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1000 RPM. Output is through an SAE B 2 or 4-bolt flange with a 7/8" 13-tooth SAE B shaft. Internal parts are common to the Chelsea 442 Series. Call us to confirm proper fit for your transmission and application.
