Pulley problem
I noticed today that my tensioner pulley is not flush with the rest of the pulleys anymore. I went to just check my fluids and saw that about 2 or 3 ribs of the belt were off of the alternator pulley. If you're looking down at it from the top, the right (drivers) side is closer to the fan than the bracket that the pulley rotates on. I put the breaker bar on the fix my belt and the pulley bracket was rubbing pretty good making it hard to move. The bearings feel good. There's no play, just smooth rotation. Any ideas on what happened and what I need to do?

Thats unusual.. When you put the belt back on properly, did the tensioner move inward or outward at all when you took the stress of the belt off? I would assume all the other pulley bracket bolts are on snug for the other drive items?

Pop the seal on the new bearing on the pulley and put some good synthetic wheel bearing grease in there. The bearings are mostly made in China and will fail quickly with the grease used during manufacture. In fact I'd repack all the pulley bearings since the belt is off anyway.

IIRC it's a T70. A few weeks ago I was in there a could not break the Torx loose on the adjuster although I did get the idler off for replacement.

I replaced all the bearings in the almost new pulley and tensioner last week. They were a T47 bit. I did the Superduty conversion on the tensioner but I don't recall that there was a difference. Possible I suppose. I still hate those things!

I'll check when I get home and I agree they are a real pain. One slip and you have some busted knuckles and probably a stripped torx head. Don't know what brilliant engineer came up with that configeration.

The same POS Torx head bolt will work. I just couldn't put that thing on my rig. I'm sure it works just fine. I didn't like the look of it.
Put a little anti seize on that bolt before installation.

Checked and the one I purchased was the T50. Maybe the T47 is correct .. anyone know for sure?

I'm looking at both right now and I can't see any physical difference between the two. Granted these are Lisle sockets so who knows. T50 is probably the correct size. Alldata says it's a 16mm. I'll check the service manual.
