If it came off easy,,,,and now is tight and difficult to get on,,,,and all you changed is the alternator,,,,then that has me thinking your new alternator has a larger pulley on it for some reason.

Could it be possible that someone installed an underdrive crank pulley at one time,,,,,and then installed the overdriven (smaller) alternator pulley to compensate for low volts,,,,,which would require a different (smaller than normal) belt.

Then when you switched alternators you now have a stock size alternator pulley, which makes it more difficult if not impossible to get the belt on.

Or maybe it's simply the wrong alternator with too large of a pulley?????

I'm just throwing ideas out here,,,,

Or maybe you have one of those rare incredible shrinking belts......

the alternator is a stock one that an ls1 mechanic i know gave me. the belt is a brand new one i bought at advance....and both the old and new pullys looks exactly the same....

Do the new and old belt look the same size?

Okay well,,,,just tossing ideas out there off the tip of my head. Did ya figure out what the hangup is yet?? Kinda hard to diagnose without actually being there.

His original post didn't mention that he purchased a new belt,,,,,I was under the assumption he was reusing his old belt,,,,,correct????

Or is there a new belt involved and I missed that piece of info????

He mentioned it in post #5 and you quoted in post #7.....or am I going nuts?

**Firebirdjones** · 04-03-2008, 03:47 AM

Okay that would explain it then,,,,,I posted in #4,,,,before there was any mention of a new belt. He didn't mention it in post #1 which is the one I responded to.
