A/C idler stud

Well, that's one misteak I won't repeat.

While dbl-checking the timing belts alignment on my '93 EA82, I found that I could take off the driver's side cam belt cover fairly easily, I couldn't get it back on until I removed the A/C belt idler. I've done it before, and it's a clever design.

This time, however, I accidentally discovered how the moveable lower stud works -- because I inadvertantly had it fall out.

If you swing the idler all the way loose (up), then take off the long 12mm hex nut, if you're not carefull, the moveable stud will fall out the back of the slotted bracket. And it's not fun to get back in.

In any other position, the stud will not come out of the slot, through the use an ingenious necked stud.
