How do I mount to engine stand?

Look on the back, where the transmission was bolted on. There is a metal cover with bolts around it's perimeter. Should be six bolts. Remove them. Be careful with the cover. It's called a pressure plate and it has some weight to it. Don't let it fall on your foot. Once removed, the clutch disc is inside and will fall out when you remove the pressure plate. Then look at the big round wheel on the back with all the teeth around the circumference. That's the flywheel. The teeth are what the starter engages when you hit the key. The flywheel has six bolts in the center that hold it on. Remove them again being careful. The flywheel is heavy too. Even with all the bolts out, it will probably be a little stuck. Just grab it at 3 and 9 and 6 and 12 and rock it back and forth and it will come off. Check the pilot bushing. That is in the center of the back of the crankshaft. They usually last a long time, but if it looks worn, you will want to replace it when you go back together with all of it.
