Hello everyone, this will be my first post on the new site. I recently swapped a new engine into my 04 Sport Trac which I know was running great and had timing chains and guides replaced prior to me acquiring the engine. After running the new swapped engine for a few days I noticed some belt squeal so I checked all the pulleys and noticed that the harmonic balancer was towards the front of the car a little bit causing one tooth of the belt to be exposed towards the front most of the vehicle and the belt was riding on the rear of the harmonic balancer thus chewing up the rear side of the brand new belt I just put on. I then proceeded to swap the old harmonic balancer from my other engine which I knew to be good on to this new engine in my vehicle to find the same problem. My question now is what could be causing this issue? I've checked all of the other pulleys for play as well as replace the tensioner to find no other issues and no other misaligned pulleys, it seems as if my issue is all in the crank pulley / harmonic balancer The harmonic balancer is torqued down to the best of my knowledge and I don't know of any other issue that could cause this problem. Any advice would be much appreciated thanks in advance everyone.
