1G Alternator pivot bolt

[talonDSMerr]

Hey guys,

My first alternator has bit the dust, and I assume it's because of the extra heat from the new setup. Anyway, I wiggle my way around and inch out nuts and bolts trying to pull the alternator. Every fastener has been removed except for the pivot bolt. The nut came off easy, but I'm having he!! trying to get the bolt out. I've tried using a crowbar to push the bolt out but it doesn't budge, pliers to at the head of the bolt doesn't work...

I know alternators go bad quick on DSM's, so there must be dozens of experts on this by now. How do you guys take the bolt out? or does it cause less of a problem for you guys?

Don't remember it being a problem. Does the alternator move freely? Maybe it's binding the bolt.

The alternator does move freely about that point. I can't tell if the bolt is bound to the alternator or not since there is a nub that keeps the head of the bolt moving with the alternator, a kind of locking feature I guess.

There's no room for a hammer either, I'm out of ideas for the night.

Yes, the end is square and fits into the bracket for space and so you don't need two wrenches to undo it.
There should be room for a pry bar.

If the alternator moves without turning the bolt then the bolt should come out.

I removed the external wastegate for more room and braced a crowbar against the o2 housing and tried to push the bolt out but I didn't get any results. I'll give it a go again tomorrow and maybe try heating the local area up and hammering around it and see if it breaks it loose.

 

[talonDSMerr]

I ground off the nub keeping the bolt moving with the alternator, but it still turns the alternator when I try to turn the bolt. So I suppose the bolt must be seized to the alternator itself. . .

This is the one thing I hate most about my DSM, is the corroded nuts and bolts!!

I don't mean to resurrect the dead here but I'm having a similar issue with my pivot bolt.

My alternator is loose and has a constant annoying ticking. I tried replacing the pivot bolt but it won't come out. I can't tighten the bolt either with a new nut it seems to be stripped from who ever installed it last time. I can slide the bolt out freely about 2.5 inches and then nothing. Almost like the bolt has flared and will not slide through the housing. I can spin the bolt and move freely either way until it hits that restriction. PB Blaster, pry bars, BFH no improvement.

Any other suggestions?

Can you grab the square head of the bolt with a pair of vice locks? Twist and pull? Maybe get a slide hammer style puller on there?
