Manual belt tensioner question... missing tensioner bolt?

After looking at the Haynes manual and realizing that mine doesn't match theirs (alternator pivot/slide what?) I did a quick search which led me to finding mine under the power steering pump. The odd thing is that it the "red rectangle" bolt in Stu's pic below is not there.



Does that seem odd? How is it held then? Just the pulley tightened really good? That's kind of scary

I am assuming that to get the belt off, I'll need to loosen the bolt in the middle of the pulley, naturally it's frozen on, so it's currently bathing in some Blaster, but the missing tensioner bolt kind of threw me off. Can you buy a replacement bolt? Should I even worry about it?

The pulley is locked down by the through bolt. You could actually adjust the belt tension utilizing a pry bar or such then tighten the pulley. Not the most elegant way, but...

Is the hole there for the bolt? I changed a belt on Saturday and I was glad the bolt was there made it easy to adjust. I am sure you should be able to buy a new one. On the one that is seized blast it and keep trying it will break loose.

yeah, there is a hole, just missing some parts. You have to place the pulley by hand and tighten it down at the same time (all the while making sure that the pulley is level)

anyone know what this tensioner is "officially" called or the OEM part number? I've looked at Rock Auto and a couple of other places and haven't found one...

thanks

The bolt part number is 6503198, $9.20 list price.

In case your pulley wheel doesn't have the correct block on the back, with the threaded hole for the tensioner bolt...
The part number and description for that is 53010149 COLLAR, Tensioner Adjustment, Tensioning Adjusting. ($5.70 list)

thanks jonny
I was on the phone with the dealer when I saw your post and he was like "uhhhhhh" then I gave him the part numbers and he was like "oh, yeah, well I already found them, I knew that"

big difference, eh?

Does anyone know the part number to the bolt that goes into the pulley collar for a 2.5L 1997 Tj?

I'm not talking about the one in red but the one that's on the idler pulley just below it and to the right.

In that case part number is 34202029. Bolt is M10 x 1.5 x 50mm long. Without pulling mine I can't say for sure if it has a wider shank or if it's 10mm along the whole length.

Same Bolt problem

Hey...I've got the same issue with my bolt. I went to and called Rock Auto Parts, but they couldn't find the part or the part number. Any suggestions on where I can find this bolt and collar?

Dealership only as far as I know. If you don't have one near you, you could try one of the online dealers.

Hmmm, going to have to pick one of these up. Mine hasn't had that tensioner since I got it from the previous owner, I've always just dealt with tightening it by hand. I've gotten pretty good at it, but I'm sure this is much easier; I'm kind of anxious now. Thanks for the P/Ns!
