All I need to know is the correct torque and additional degrees to turn ratchet for the Harmonic Balancer on a 97 SLS.

Thank You

With your help I can end this movie. I raised the body from my car 4 ft in the air while leaving subframe on ground. I did so using a small range of tools from pullers to a very small jack, tons of wood, and 4 jack stands.This was necessary to repair cars head gasket failure. However, I have done this at least 5 times on the same car within a month. The head gasket repair was easy including putting every thing together again. When I reassembled car to subframe the first time, the only nut I failed to torque out of many was the harmonic balancer. This caused it to have a light knock. I assumed I did not time it correctly so I dropped the load and reassembled it after timing. That was done on numerous occasions without HARMONIC BALANCER EVER INSTALLED. The knock was 10 times louder every time I timed it WITHOUT INSTALLING "BALANCER". Until today I was just starring at it, contemplating how to remove only the engine from top, in order to inspect everything bolted on block. Until one flew over the ko-koos nest and gave me a crazy hypothesis for my experiment. To conclude, I found out the importance of a harmonic balancer. I hope I did not bend or weaken anything that will cause a engine knock. The 3 jaw puller I used to remove balancer was a loaner tool from autozone, so I decided to leave balancer off until I got the engine to stop knocking. I assumed the "BALANCER(s)" only purpose was to do what I seen it doing(spinning all pulleys connected to belt). In a million years would the engine have stopped knocking without HARMONIC BALANCER being torqued correctly?
