I appear to have lost this, although nothing is loose yet.

I cant find a size of the bolt though, Ive searched here and online. Dorman makes a generic toyota one for like $12, but not sure will fit. Anybody have this size? Thanks!

Thanks!!

I seem to recall that the adjusting bolt is prevented (a pin on end?) from unscrewing fully from the pulley spindle, so to take it off you undo the pulley retaining nut, remove the pulley and the bearing, and slide the spindle and adjusting bolt aft out of the cast bracket.
Did yours somehow actually back completely out, or did it shear (fully or partially, then snapped off later) when somebody tried to adjust it with the pulley nut still tight? That happens....
It's a fine metric thread, 14mm AF head, with the bolt shaft fully threaded, and about 4-5 inches long (again, if I recall correctly). I'm sure if you take the pulley and spindle off, a machine shop could make up an adjusting bolt to fit.
 
Not sure what the prices are like for Toyota parts, but I’ve swapped my tensioning bolt over to a zinc plated version as my old one had seen better days. What you’re looking for is a metric fine thread set screw. From memory it’ll be M8x1.00 and aim for say 100mm long. My local bolt store stock them for like 50c each... of course I live in one of the 192 developed countries here on earth, so if you happen to live in the backwaters of Burma, Liberia or the United States you might be out of luck... :)
 
Just pulled mine out, and here it is. It's a special bolt, M8-1.25 (ISO metric coarse), threaded length is 9.7cm, the retention collar is 1.5mm thick, and the collar to head gap is 10mm.
It's been well over a decade since I had it out to replace the idler pulley bearing, so proper time for a clean and refurbish! Thanks!

And just in case you want to replace the bearing while you're in there, it's an NSK 6302DU C3 270.
 
You guys are awesome, I spent over an hour searching! I’m not sure why nothing has moved but belt is still tight.

Thanks everyone for the help!
Here’s a picture just for fun,

Nothing has moved (much) because the bearing spindle nut (the one on the front) is tight, holding it together.
If you go for a long M8-1.25 bolt, drill a couple of wire locking holes in it before you install it, so that once it is secure, and taking the tension of the spindle, you can wire lock it so that it won't back out and get lost.
 
Sorry to bump an old thread, but 90119-08493 is about an inch shorter than my 3bii's tensioner bolt that has seen better days. Anyone have a good part number for a replacement or should I just get a m8x1.25 100mm bolt and drill hole for a locking pin?

if any help the 2h tensioner bolt is 110mm from under the head m8 1.25p, looks very similar if not the same.

I dont suppose anyone has a part number for that bolt? I've been searching for 2h or HJ60 bolts and cannot find the part number to try and order one.
 
Thanks @OGBeno!

*Edit: 88446-35010 is 10mm shorter, but available in the US for cheap (under $2) and works. Thanks!
