Alternator Removal Help.

Alright, I started doing the work today to replace the oil filler tube and coolant tank. All was going well until I got to the alternator. I read the DIYs, and I followed them to the T. I turned the right bolt three turns and hammered it until I got tired, took the bolt out, took the left alternator bolt out...dead stuck on the right side. The metal bushing on the right side of the alternator looks 100% frozen. I used the penetrating oil on it, and hammered it directly with a tap and a rubber mallet- still no go. I am not at a loss here. I am scared to use the pry bar on the alternator, but that seems like the only remaining option. I already broke the POS Connection Piece for Oil Separator Hoses while removing the intake plenum. The plastic inside the connector was brittle and pretty much disintegrated when I tried to remove the broken plastic from the hose. Any ideas or suggestions are welcomed.

I had the same issue.. If I recall, I used some sort of extension (maybe a piece of wood) so that I could hammer on the bolt from outside the engine bay. Its really hard to get a full swing from inside the engine bay. Mine went all at once when it finally loosened. When it does go, the bolt head will move inward so that it is flush (having taken up all of the "slack" from your loosening the bolt).

Thanks sjg. I will call it a day for now and go grab few beers, I've been hammering at it for 5 hours in AZ heat and high humidity today. I will start pounding the bolt and bushing tomorrow after work.

Get one of these. Take out the chisel and put a brass/aluminum/wood/steel rod in it and pull the trigger for about 3 seconds. http://www.harborfreight.com/air-imp...kit-92037.html

I soaked it with Kroil and used a 1 foot round aluminum bar to hammer it outside the engine bay like Steve did. However, be careful though since the anchor is part of the engine case and you really don't want to break it.

Same experience, same advice. Soaked the rear alternator bushing with WD-40 for two days. I still had to give that bolt head more of a whack then I really thought necessary. Used a brass boat prop shaft about 2 feet long and a heavy ball peen hammer, tapped and tapped, and tapped, and tapped, then finally gave it a really hard whack and it moved just enough to get the alternator out. In the end even that was not enough to get it back in. Tried many times to get the alternator to mount on the right side, no way. Set alternator on bench with support under the bracket/bushing and drove that bushing in almost flush with the bracket. Piece of cake installing. Then when you tighten that bolt, POP, the bushing reseats and you got it. I was replacing my oil filler tube as well. Pretty simple when the alternator is out. Make sure you observe the routing of the coolant hose in relation to the oil filler pipe. It goes to the right. Your fitting is broken so that won't be a problem. Please resolve that broken plastic fitting with a better fix...get a brass nipple and two SS clamps from the hardware store. Make a bracket from the existing piece to hold it in place with a zip tie.

Thanks Joe, appreciate your comment. It seems that sticky alternator is a very common issue. And +1 on the brass fitting, I went to the NAPA Auto Parts yesterday and bought 3/8" quick connect brass fitting, it is a perfect fit.

I found it very difficult to tell when it had loosened. I used a long metal rod I had so I was able to swing the mallet outside the engine bay. Be careful it does not slip and hit anything else. Even though I had rags in place, the rod slid a bit and wore a touch of paint off the black trim piece on the bottom lip inside the engine bay. After a few good wacks I couldn't tell if I had done anything. I removed the left bolt and wiggled / pried until it came free. If you are following the directions from Pelican which have you remove less components than the factory manual, you will discover that there is exactly one way the alternator will come in and out, but about 1 million ways it won't. It's kind of like the two twisted nails puzzle.

Update, after an application of penetrating oil and an hour of pounding I was able to get the alt out. Pounding the bolt was not doing anything, so I removed it and started hitting the bushing directly. I used a 3/8" 5 inch long extension to reach the bushing and hammered the extension. Thanks for the suggestions everyone. I should have the new tube in tomorrow and will move on to the coolant tank.

Installed the new oil tube today. Every DIY on the subject has been completely off regarding the removal of the TB and intake plenum. There is absolutely no need to remove either item and that saves a huge amount of time and frustration when it comes to re-installing the intake plenum. Both bolts that secure the oil filler neck to the block are accessible when alternator is removed, removing the intake plenum and TB is a complete waste of time. One bolt holding the filler tube is on the back of the alternator bracket, the second bolt is directly behind the filler tube.

Re-installed the alternator today. My bushing was still in the fully "out" position, so I had to improvise. I took the bushing and a 25MM socket to Harbor Freight and used one of their big bench vises. You put the 25MM socket on the back side of the bushing and start squeezing. 25MM is wider than the bushing and it allows it to retract, while it is pushing against the alternator mounting bracket. With bushing fully retracted it took me 15 seconds to re-install the alternator.

Did you replace the coolant tank before re-installing the alternator? Just wondering if it is any easier that way. Congratulations on the DIY repairs!

Joe, alternator has no impact on the coolant tank replacement. Driver's side intake manifold and fuel/AOS hoses are the items that restrict the coolant tank "maneuvering".

Reassembled everything and test drove. All systems go. PS. I really grew to hate the ****ing clamps and connectors Porsche uses everywhere. The spring clamps on every hose and connectors that require squeezing specific parts (parts that for some reason are all ****ing pointing down or away from you) had me using many many curse words. Alternator removal which in theory should take 5 minutes took me hours.

Great job, thanks for posting. Very informational and I know what to expect.

I hear you on the clamps. I -briefly- considered replacing them all with some other solution.

Having the same issue currently with removing the alternator. Is the bushing attached to bracket or is it part of the alternator itself? And how do I know when it comes loose? I have knocked the crap out of the bolt and removed the long bolt and still no movement of the alternator? Guess I need to hit it harder?

THIS: Amazon Amazon or even better: Amazon Amazon Makes those horrible water hose clamps go much easier. Once connected, they lock so you can move it around without having to apply pressure. You still curse doing it, but not as much.
