So my harmonic balancer slipped off while cruising down the blvd last weekend. Luckily the balancer,pulleys and belts got jumbled up by the fan and didnt get lost. Im going to start the repair this weekend, but need to know how to install the Harmonic Balancer. Does it require the HB installation tool or can i just bolt it back to the center of the crank. I can slide it on by hand, carefully aligning the notch in the crank and HB. Im not sure if this is correct. Help!
