The Chelsea 489 Series Power Take-Off Assembly, part number 489GHITX-V3AZ or 489GHITXV3AZ, mounts directly to the 8-bolt PTO opening on compatible manual transmissions including Eaton Fuller, Volvo, Mack, and others - no adapter plate required. The one-piece cast iron housing eliminates a potential leak path and delivers the same intermittent torque capacity as the 442 Series: up to 250 lb-ft (339 Nm). Output is an SAE B 4-bolt flange with a 1-1/4" 14-tooth SAE C shaft. Shift is air shift. Shaft power ratings are 24 HP at 500 RPM and 48 HP at 1,000 RPM, with output power in the 46-55 HP range. Internal parts are shared with the 442 Series, simplifying parts sourcing. Call us to confirm proper fit for your application.
