OK, on my daughter's Pontiac the crankshaft pulley has a outer ring that essentially separated itself from the inner portion of the pulley! I don't see any way of putting it back on there, except... glue? What the...

Slipped Balancer. Its been bad a long time. No fixing it,must replace it with a new or atleast good one.
Replace only and ASAP. Dayco makes an aftermarket one that is decent.

It's done. Fix it before you run it any longer.
I often see them develop enough runout to throw off the belt.
Crank pulleys aren't repairable. Replacement is the only option.

Yeah, it already threw off the belt. Amazingly, we drove it five miles home while the belt had no tension whatsoever.
Any tips for getting the remainder of the crank pulley off there? I got the bolt off, but the rest doesn't want to budge.

You need a puller

Do you have a proper crankshaft pulley removal tool?
I never had any difficulty removing a 3100/3400 pulley with a generic pulley tool.
Also, know when your belt tensioner was replaced. I often find that the existing tensioner is almost as out of alignment as the crank pulley.

Super easy to fix take off drive belt unbolt it and put a new one on in under an hour it really is a 1-2-3 job very common on high mileage 3.1 engines. If you can replace a fan belt on an older car you can do this. Remember hoe the drive belt goes take pictures if it makes you feel better although there was a diagram on the hood or body of the car..
How many miles on that 3.1 and what year?

You don't need a puller on that engine it may help if rusted on but we just take them off of most of them. Tell us what year.

I did it to my moms Buick Rendezvous with the 3.4L (basically same engine) last year. It's an easy job, hers did the same thing and separated except it chewed up the belt doing it. You'll need a puller. My mom's is an Arizona car and it was stuck on.
depending on the year some come off without a puller.. also check your water pump for seepage they are also very easy to replace and are under $20.00 Wholesale
