Alternator Idler pulley
I am trying to remove the alternator.
Is there a trick to removing the idler pulley bolt? :confused: I read that the bolt is left-hand fastening. I must have turned the bolt at least 360 degrees but it is not getting easier. Is this normal? I am using a socket and the bolt is stripping. :eek: Thanks in advance. |
Update
--Update----
The bolt is officially too damaged for a socket. I can still use the boxed end wrench. I searched this forum and read Mike Yi's recommendation to use PB Blaster. He said to use it a day before and an hour before. Well, it is a bit late for me but perhaps late is better than never in this case. The PB Blaster ordered. Three questions to 986 experts in this forum. 1. The bolt IS LEFT-HAND FASTENED meaning I must turn clockwise to loosen it, yes? 2. How to remove the stripped bolt? The battery is fully charged. I can drive to a mechanic. 3. Is it time to give up and seek an expert? Thanks in advance. |
The pulley bolt is out!!! :cheers:
The pulley bolt is out!!! :cheers: (This post must be a some sort of record for the OP posting 3 straight times. :) ) This is what I did. It my desperation, I turned the bolt the counter-clockwise and it came off. The bolt WAS NOT LEFT-HAND fastened at all. It was a good old, "righty tighty lefty loosy." I am a bit confused as there are MANY how-to-articles on NET that state the bolt is left-hand. Here is one. https://sites.google.com/site/mikefocke2/replacingyouralternator I will upload the picture of the bolt that clearly shows the cross-section contraction as the result of the tensile load I was giving it. Thanks for the silent support. :cheers: :cheers: |
my one word of warning - one bolt i thought must be completely removed, however it was only meant to be loosened. by removing it, the install was a lot harder than it should have been. also, it is very easy to break some of the housing bracket with too much force when trying to pry the alternator out.

My concern at the moment is WHY my idler bolt came out by turning it CCW. Watching the videos online, it looks to me the belt is spinning clockwise. Assuming the belt's CW path is true, it makes sense that the bolt should/would have been LEFT-HANDED so that the bolt does not loosen with friction. Do you have any insight? Thank you Tony. |
Mike's site did not say the bolt was a left handed thread; it refered to the bolt on the right and left sides........

After reading your above post, I went back and read it again. Here is the section that confused me. "* Unbolt and remove the Alternator by unbolting the right hand fastening screws, loosen the left hand fastening screw by three turns,..." I now see it clearly "the right hand fastening SCREWS." :) JFP, how is the pulley bolt considered left hand? (Would you believe I LOOKED UP "left hand fastening" just to be sure? ) Anyway, I am VERY happy this morning. I now need to get the part number for the bolt. :) Thanks again JFP |

However, I am still a bit confused. I want to get this right so that I don't make the same mistake in the future: -There is two bolts holding the alternator. One about 7 o'clock of the alternator - this one is about 1 1/8 inches long, and the idler pulley bolt. -Looking at the alternator from driver side, the idler pulley bolt would be a the bolt on the RIGHT not the left. JFP, am I missing something? I mean no disrespect by asking this question. I know I have much to learn about fixing this or any other car and I just want to learn correctly. Thank you in advance. |

http://www.pelicanparts.com/techarti...small/Pic3.jpg The comment on Mike's website was refering to the "left handed fastening screw" (the one at 7 o'clock in the photo), and the "right handed fastening screw" is the idler bolt (at about 5 o'clock in the photo). My point was that Mike was not making any reference to the thread type (left or right) in his comment, only the location when you are looking at the alternator.................. Unfortuantely, Mike's instructions does have the bolts reversed as to which one needs to be tapped, which probably is adding to your confusion. http://www.pelicanparts.com/techarti...small/Pic4.jpg |

Thank you JFP. BTW, it is not only Mike's instructions. There are others too. |
