Alternator Removal

[cornontherob]

Hi all,
I'm in the process of an alternator replacement, and I cannot for the life of me get it out. I have the lower (passenger side) bolt loosened so that it can pivot and I'll be able to get it out. I loosened the idler pulley bolt a couple turns and sprayed the rear bushing with WD-40 and a rust solvent. I've been using a soft hammer to hit the bolt to knock the rear alternator bushing loose with no luck. I've let the bushing sit with both sprays on it overnight, with no luck. There's no room to safely fit anything like a torch. What do you suggest I do? Is there another way to get this off that i'm not seeing?

WD 40 is a Water Dispersant.
Try Kroil by Cano Labs.
There was a recent thread on this subject with some good links and suggestions.
While you are waiting for the repeated applications of Kroil to work over a period of many days, check the pulley bearings and w/p bearing.
No flames ! Save the hammer until the Kroil has had a chance. Did you read the Pelican diy article?

I've been using the pelican article, however I'll try the Kroil and let it sit for a couple days! Thanks!

You are right on track, it does take a good wack on the bolt though. Just went through this. Next would be the same method after PB blaster soak for me.

[cornontherob]

Alright, it turns out that the other solution I had been using was also PB blaster. So I re-applied generously, turned up the heat in the garage, and I'll let it sit overnight. However, it has made seemingly zero progress with the hammer method. Would you recommend getting an air hammer and doing it? Or should I just bite the bullet and take it into the local shop

I just did mine this week.
Zero issues, maybe I got lucky.

WD40 on the bushing, then a good wack with a hammer and a punch on the head of the iddler bolt after loosening 3-4 turns.

I found that once the bushing was loose, I removed the alternator mount bolt and had to wiggle it out by pushing up then tilting before pulling out.

Installing the new alternator was a little more tricky. I had to wiggle it in without the long bolt, then tilt the alternator a little to allow the long bolt to go in... then the mount bolt last.

Just did it myself too a month or two ago. It certainly is a pain - just keep hitting and struggling and cursing. Spray the bushings with PB Blaster or similar product. Leverage with screwdrivers. It'll come out eventually. Don't give up!

[Gelbster]

Just a hint - when they say "Hit", I hope they mean tap or rap . Tapping and any other motion helps the penetrant seek a way through the corrosion. Patience & Persistence. Hit too hard and the damage may be expensive. Squirt the KROIL on the obstinate part from different angles if you can.
Good luck !

Okay I've been repeatedly hitting and reapplying the pb blaster over the course of the past two days. Zero luck so far. I've sprayed the bushing from both in front and behind, yet no luck. Gentle taps all the way to hard hits. So I tried that, it didn't work. I also did the same thing while prying the alternator upwards with a pry bar. Still no luck

[patssle]

You've been hitting the bolt that goes into the bushing? And prying at the right side of the alternator underneath trying to force it up.

Edit:
Bushing has been loosened. It took a couple more hours of pounding and re-applying pb blaster into the bushing, along with a copious amount of wiggling, but it's finally loosened. However, the next issue is getting the alternator out of the space it's currently in. Right now, the lower (left) bolt is blocking it from coming out. I've been attempting to maneuver it out, but I figure if anyone here has done this before and knows exactly the trick to getting it out, I'd appreciate it!

Any update?

Hope you get it all squared away.

[cornontherob]

Unfortunately I've been out of state for a few days so I haven't had the chance to really get at it. I was cut short on my time getting it out, so hopefully tonight or tomorrow I can get it out

[cornontherob]

Okay so this should help visualize my current issue. I can't get it past the lip of this bolt hole. I don't know if there's a certain way to wiggle it, or if those who have attempted it have successfully removed the whole thing.

After getting the bushing loose, you can remove the pulley bolt and the lower bolt. Lift and rotate the alternator counter-clockwise and it should be able to move free of the lip.

[cornontherob]

I apologize, I took that prior to removing the idler pulley bolt and the lower bolt. However, if counterclockwise is the way to go, then I'll try it for awhile and see if it comes out

[cornontherob]

Alright, it's out, tested, and a new one is about to be on its way. Thanks for everyone's help!

[Gelbster]

I suggest you might do a write-up of what you learned about Alternator Removal for those who follow ? Particularly which things to loosen/remove & which way to rotate and why.

[cornontherob]

Will do. Hopefully I can get a thread going in the technical help area in the next few days. New alternator ships in first thing tomorrow.
