Hyundai H100 - 2001 Diesel

Hello everyone, I have a doubt .. I buy a new Hyundai H100 engine .. and I want to know how I take the engine? Why does the engine have it below the seat and I can't put any rig to be able to get it .. Could it be that it comes out? I have to take out the entire front train? If anyone knows, I need help. Thank you very much ..
