Was that with a low battery connected or no battery? The teeth on most clamps don't provide enough surface area to pass a lot current, going directly to the starter terminals helps and I don't know what takes to turn a IH584, but you won't start my 7.3 liter diesel that way there is a reason it has twin batteries and cables the size of your thumb. Also the starter my sound fine on the bench but still have a bad solenoid that won't pass enough current, open and inspect contacts, sandpaper and bend into good alignment
