Alternator pulley getting really hot

I replaced an alternator/fan belt on my 3.2 engine that was about to give in.
After replacing and some spirited driving I noticed that the alternator pulley
is getting really hot (I can touch it for about 2 secs).
The alternator belt is tight, but has 5-10mm play.
I added one shim and it feels too loose (15mm)
It would wobble a bit when the engine is on.
When I turn the fan by hand the tight setup would turn the engine, while
the loose setup would not.
The fan itself turns freely, no grinding or getting stuck.

Here are a few more details:
- The alternator pulley has been chrome plated (not by me).
- The engine pulley is a non-AC pulley from a SC and has been bronze (?) plated
- The alternator light does not come on when the ignition is turned on, but the bulb is okay.

Is it normal that the pulley is much hotter than anything else surrounding it?
What else should I be checking?

Thanks
