In the midst of my first ALH timing belt change. So far, the valve cover bolts were an issue, then the harmonic balancer bolts were an issue. Now I've finally got the harmonic balancer bolts all out, and the harmonic balancer won't budge. Any tips? I see extra holes in the harmonic balancer hub, but they don't appear to be threaded holes that I could use with a "harmonic balancer puller." I'm thinking that using a regular 2 or 3 jaw puller is going to mess up the surface the serpentine belt rides against. Based on my internet research this evening, it looks like the bolts are always getting stuck, but doesn't look like the getting the balancer itself separated from the crank pulley is a common issue on this engine.
