So I'm finishing up bringing everything over from my old motor to my new motor and can't figure this out. The idler pulley from what I can see online is supposed to have a bolt through the bracket and into a threaded hole on the back of the pulley. Is this correct? Mine has a hole in the bracket not threaded and then just a nut on the back of the pulley. How's this setup supposed to work and what do I need to do about it. Thanks.

 

What engine are you working on?

 

It's a 22re

 

Do you have a picture of what you have?

Mine looks like the one you describe you seeing online, with the pulley looking like this: https://www.yotashop.com/toyota-4run...ey-4435035010/

 

 

That's what I was afraid of. $148 that's insane. I guess someone lost the bolt and threaded piece and replaced it with a nut.

 

On my 92 pickup the head of the bolt is missing. Do you know the bolt size?

 

It's the same exact bolt as the 4 that bolt that bracket to the block under the dizzy...
you could just pull one of those 4 is over kill on that bracket.

 

Thanks

 

well, hold on, we may not be talking about the same thing...
I thought you were talking about the "bracket" bolt in the Pic...
but your actually talking about the bolt that goes thru the idler pulley?
That may be different... sorry

 

Yes, I was looking for the adjustment bolt on the back side of the bracket/pulley.

 

Duh...I see the adjustment bolt missing in the Pic now....
you might try the 4Runner house in garland tx...

 

So far as I can tell, it's just an ordinary (flange head) bolt. If I had to guess, M10-1.25 x 100mm or so. Take the pulley down to your local Ace hardware, and ask for their assortment of metric bolts. Very carefully try an M10-1.25 to see if it fits. (The 100mm is really a WAG; try measuring how much throw you need first.)
