What tools are needed to replace the timing chain?

There are some special tools to hold the rear of the camshafts in time while the timing chain and guides are being replaced. Also, there is a special tool that holds the crankshaft from turning when you loosen the front damper bolt to remove the harmonic balancer, I have included in the diagrams below the instructions on how to do the job. Make sure to disconnect the battery and drain the coolant first. Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.
