As you've probably known, the bolt has a very shallow head.
This was the main problem. I had to build a jig to steady the
tool. After some thought the jig was nothing but two blocks
of wood (a 2x4 and a 2x1) and it was freed easily. :~)

I see. But looks like I do this at a later time. I'd set up the
chain come-along but I can't locate a buddy of mine who
has a 5-ton crane scale.

The 88 Accord pulley bolt which I believe had driven some
80k miles before the belt was changed was loosen easily. The
92 Accord was driven about the same miles but the bolt
needed help from a machine.

After 375k I've done a bunch. It was a bitch the first time and it was a
bitch the most recent time. In all cases the usual 250ish foot-pound
impact wrench on a quarter-inch hose wouldn't budge it, though I wasn't
willing to spend all day on it before breaking out the big guns.
