Hi, I am new to the website. I need to replace the Harmonic Balancer on my 2005 Ford Explorer, 2 wheel drive, 4.0 gas engine. There is some pretty good posts on this website on how to determine if a harmonic balancer is defective and some info on replaceing it. However, there is one thing I am confused about and that concerns getting the engine to TDC and making sure it stays in time. Some posts say to make sure you secure the harmonic balance with some kind of wrench to make sure the engine does not turn when you loosen the bolt securing the harmonic balancer. Other posts say it is not an issue because the harmonic balance has a keyway in it and it can only go in one way. Can someone tell me which is correct? It seems to me that even if the engine turns it shouldn't matter unless it is turned when the harmonic balance is out of the engine.
