Listen to this crap...can't believe my eyes I'm driving home about an hour ago and I start to here my belt squealing. I also feel my power steering making it harder to turn the steering wheel.
So I pull over and the first thing I do is grab the belt near the power steering pump. The belt is loose enough where I can take the belt right off if I pulled it forward. So I figure my Katech tensioner came loose...NOPE. The friggin pulley that is (or was) on the Katech tensioner is GONE
I don't mean the entire round thing with the tracks in it. The bolt is there, the front part of the pulley is there, the part that the belt sits on with the tracks in it is GONE. How could that depart the assembly? It would have had to split in half and than fall off. Its metal isn't it?
I drove 9 miles home very slow, when I was about 1 mile away from home my check gauges light came on because my volts were draining and the temp started to rise because the water pump wasn't getting spun its normal rotations. The power steering was sluggish the whole time.
I get the wierdest **** happening to me, oh well
I'll get some pics tomorrow.

Do you know if they're metal or hard plastic?

$10 or $15 bucks and you'll be rolling again...

Did you set the belt tension as described in the instructions? I can see if the tensioner was very tight causing extreme load on the bearing, heating it up and melting the composite pulley.

I just made the belt pretty snug each time I had the belt off over the past couple years, which was off maybe 10 times.
How tight should it be?

Use a torque wrench to apply 25 ft/lbs of tension to the belt. Tighten the shoulder bolt to 40 ft/lbs. Re-check periodically.
From my experience at working at dealerships I seem to remember L67 (3800SC) engines having problems with tensioner pulleys. They would break in exactly the same way. The pulley would come off the bearing and all that was left on the tensioner was a bolt and a bearing. I don't know if it was from too much tension, but I would guess that bearing was overheating and melting the pulley.

Probably after a given number of years/miles the stock plastic pullies should be replaced anyway (at least when they start making noise). The bearings are sealed, non-replaceable deals and this is a wear and tear, non lifetime item after all.

Thanks for the torque specs, I'll do it right now.

Yeah, I immediately checked because my steering was sluggish, I first thought my power steering pump failed.
