You might consider pulling the alternator, if it has the same mounting configuration as the XR2. I pulled mine when I had to service the belt drive system last fall. Turned out that even though I hadn't noticed an issue, the voltage regulator lost a diode on me, so the guys at our local alternator shop replaced it with my good used spare. It was very difficult to get it out of there.
Also, take careful note of how the harmonic balancer assembly comes apart. Whoever had mine apart last put the bolt ring in as a spacer rather than a retainer ring, which might have contributed to the shearing of 2 of the 4 6mm bolts that hold it all together. Putting that back together correctly is essential to keeping it together for the long haul.
My 2 cents
