Step 2: Help
Another great thing to have is someone to help you, preferably someone strong who knows what they're doing. Luckily I have a brother who has done this stuff literally his whole life who made this project possible. You can probably manage to pull the engine alone but dropping a new one back in would be crazy difficult. Be sure whoever helps will not get hurt because it is hard work. It is also super filthy work. Wear some coveralls or old clothes that will be ruined. Also get nitrile gloves if possible and have plenty of handcleaner, papertowels and a 5 gallon bucket full of water around to dunk your hands in. Your hands will get greasy and its hard to hold tools. You will also probably cut and nick your hands fairly often when not wearing gloves so you might want to clean the cuts out.
