The Chelsea 489 Series Power Take-Off, part number 489ZFITX-H3XK or 489ZFITXH3XK, mounts directly to 8-bolt manual transmission openings on Eaton/Fuller, Volvo/Mack, Tremec, and other compatible transmissions - no adapter plate required. The one-piece cast iron housing eliminates an adapter plate and its associated leak path. Intermittent torque capacity for the 489 Series matches the 442 Series at 250 lb-ft (339 Nm); shaft power output is 24 HP at 500 RPM and 48 HP at 1,000 RPM, with an output range of 46-55 HP (31-40 kW). The output is an SAE B 2 or 4-bolt flange with a 7/8" 13-tooth SAE B shaft. Tapered bearings replace needle bearings for increased load capacity. Call us to confirm proper fit for your transmission and application.
