Anyone know where I can buy the proper bolt for this? I’m actually a little impressed with this. Clearly this fell off at some point as it’s the wrong pulley and there is blue lock tight on the fabricated bolt.

Oh weird, ok. I don’t know where this pulley came from, it has a flange on both sides where as OE has none. It’s not a big deal, this one is not why I have this apart. My tensioner pulley bearings are bad and I figured I would check them all/replace while it was apart. Thanks!
 






I kinda figured it would look something like this maybe.
 


















Wow! Ok thanks bro! I’m having a fun time with this fix, bought all three pulleys, the one for the tensioner didn’t fit (still running that rigged up bolt on the idler) so I bought a whole gates tensioner. Installed it and the pulley bolt stripped out when I tried to install the belt! Lol so I found the oe part number from ford and found one for $40 on amazon.

Update: the amazon parts appear to be legit. Just dropped this factory tensioner in, only started it up but I think it’s good. The part and box looked like ford dealer parts.

I've got a stuck bolt or a seized bolt on my idler pulley 97 Ford Explorer XLT control track I've seen a lot of ideas not sure what's the best idea.

Depending on how far you want to go and how long the vehicle can be down, there are a lot of options. General escalation method would probably be best. Soak it down with penetrant, let it sit (overnight if you can) heat it up, juice/heat/juice/heat etc. If you can reach, wack the top of the bolt head one good time, and then with a breaker bar or equivalent tighten the bolt slightly. Yes, turn it the wrong way first, just a hair. That will usually break it free.
If that doesn’t work, differential heating/cooling might. Heat the material around the bolt and use a can of duster upside down to freeze the bolt.
After that you’re into breaking and drilling territory.
Good luck!

Looks like they tried to create a "Shoulder Bolt." Do a search on "Shoulder Bolt." I found McMaster-Carr has quite a selection & in my experience, Ace Hardware has about the best selection of fasteners of all brick & mortar stores. You may need a Grade 8 bolt for this application.
 






Thanks @MrClamps ! That was 3 years ago. I just used that cobbled bolt and it’s working fine. If I ever have to take it apart again, I will definitely remember SHOULDER bolt.
