Are you sure you have the correct size belt for that model. I just serviced the deck in my Hitachi 3D7 (same deck). I had the same issue that was fixed by replacing the main belt. The old belt looked ok but it had stretched. Try a slightly smaller belt and see if that resolves the issue. A loose belt in this deck will also result in a weak FFWD.
