Want to remove pulley to replace new pulley on alternator. Can i put a hex socket or conventional socket (size?) to enter through the entrance of the pulley turn it counter clockwise while holding the shaft of the alternator with a belt to hold the pulley as it turns?

Frankly i don't know what it looks like inside of the entrance to remove it.

I saw a hand made tool but directions are sparse and pics doesn't reveal enough without explanation

I know i can buy 60.00 tool to remove it and then another 50 for the pulley, but budget won't allow both. advance doesn't even have an alternator with the decoupler pulley on it, besides it's a 160 bucks and i don't have a bad alt.

i saw video saying the oad is necessary or other pulleys will get too much tension and shorten their lives.

 

You can remove the alt, take it to your local NAPA store and they can change out the pulleys maybe free of charge. You have to use an impact wrench to get the nut off.

 

It takes a special tool to remove the decoupler, here is r and r information

this is the special tool

 

Thanks tizzy--i was trying to find out the internal exacts of the pulley so i can manufactured some type of sorts or use allen wrench. would you happen to know if the right side of the tool above in the pic. is allen wrench shape and what size?

I was wonder if the right side of that tool was what goes into the entrance of the pulley?

There is no way i can buy that tool at this time. thanks again.

 

I've never actually done it. I'll look at the tool when I get to work on Monday.

 

Thank you I really look forward to understanding what it looks like and size.

 

when you pop off the cover of the pulley, there is a 17mm allen hole. Inside it is a 10mm bolt head. I think the tool holds the pulley while turning the bolt head. I took some pictures but am still trying to figure out how to post them.

 

appreciate
