The Chelsea 489 Series Power Take-Off Assembly, part number 489XLAHX-A3RY or 489XLAHXA3RY, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Volvo/Mack, and Tremec. The one-piece cast iron housing eliminates the adapter plate found on earlier designs, removing a common leak path. Output is a rotatable DIN 5462 pump mount with a DIN 5462 shaft (B8x32x36). The 489 Series delivers intermittent torque in the 201-300 lb-ft range and shaft power of 24 HP at 500 RPM and 48 HP at 1000 RPM. Air shift is standard on this configuration. Internal components share commonality with the Chelsea 442 Series, simplifying service. Call us to confirm proper fit for your transmission application.
