Counterclockwise
get a longer bolt to start it . use this bolt until it is pulled up enuff to start the proper bolt
First remove the old one using a puller that you screw into the harmonic balancer there is a key on it so you can not put the new one on wrong just use the bolt that holds the main pully on to push the balancer on
The big bolt that holds it on must have came out of the crank.
I have not taken one off a 74 specifically but every one I have done required a Gear Puller. The puller will bolt to the Harmonic Balancer and the center bolt sets on the head of the Crank Shaft bolt. As you turn the center bolt in it will pull the balancer off.
Pull the belts, remove the center retaining bolt then use a harmonic balancer puller to remove the pulley. Make sure you use a disk that will protect the threads of the cranshaft when you tighten the puller.
on the harmonic balancer, at crank shaft
Pretty sure that it is in front of engine directly above AC Compressor and to the right side of harmonic balancer of Crankshaft. It is mounted horizontally with 2 wires connected.
After removing the bolt, use a large gear puller. Tighten the puller, tap the head with a hammer, then tighten again. After a few repetitions the balancer will break free.
You need a pulley puller.
