OK,
I just got a air compressor with a impact socket, tried to remove the altenator pulley and no luck! Is it reverse thread? I put some wd-40 on , also how do you hold the actual pulley (fan) from spinning? Any help would be great.
Thanks alot!
If you have the belt off put it back on until your have it lose. Also if that doesnt work, try putting a screwdriver in the alternator fan blades, thats what i did and it worked for me, and i didnt even have an impact wrench
Stock alternator - put a 5/16" allen wrench in the alternator shaft and a 15/16" wrench on the nut. The allen wrench hole in the alternator shaft enables you to keep it from turning while you wrench on the nut.
I would not recommend sticking a screw driver into the fan blades. It's very easy to bend/misalign things that way. They make a 'strap wrench' - a big handle with a piece of rubber strap not unlike a fan belt. You can wrap it around the pulley and cinch it up - hold the pulley against the impact wrench. If you have the allen socket, as jrichker suggests - put a wrench on the bolt, and put the allen socket on your impact - be sure you set the impact wrench to turn clockwise if you try this approach.
I tried and tried with no luck. I just installed the altenator back on with the stock pulley. I will try later to see if I can get it off now with the belt back on. Will it make any differance if I leave the stock pulley on? If I do buy a new and improved chrome altenator, will it come with the stock pulley or what?
Thanks again for all of your guys help.
I had a pulley put on by a shop and it came loose. So I got another lock washer and nut....custom very wierd size. Then I used an old belt, big set of water pump pliers and locked that with vice grips...kind of a make shift strap wrench. Torqued the sucker to 80 ft lbs and it is holding fine.
