belt adjusting screw

I had the misfortune of breaking the screw that adjust the belt. Not only is the belt still squealing but the bolt is broke in it. I am probably going to have to pull the whole bracket just to get to the screw. anyways. does anyone know what size this bolt is. I am going to try to find a grade 8.8 or better bolt for it.

On my '95 YJ it's an M8 1.25 mm thread per inch and its 100 mm long. I couldn't find it at the local auto / hardware stores. I got one from Mcmaster Carr. Part number 93635A353.

I did the same thing and had to order one at the stealership despite exhausting every other option.... it was only a few bucks and a couple days wait.

If you broke your adjusting bolt by just tightening it without loosening up the pivot bolts, or the locking bolt that locks the tightening slide the adjusting bolt goes to you need to look at that part of the task. You have a 4 cyl, mine is 6 cyl so I can't send any photos that might be helpful.
If you do go with a hardware store bolt, and not the orig bolt, you need to make sure the entire shaft of the bolt is threaded, not just the last inch or so like most of them will be. Hope this is helpful.

On my '95 4cyl, you can separate the mounting/ adjusting bracket from the pump. Just remove all of bracket to block mounting bolts - the pump stays mounted by the top bolt to the block.

Once on the bench the correct amount of PB, cursing and heat will get the remnants of the bolt out.

i loosened all the other bolts that where necessary to tighten/loosen it. the problem was, im assuming, the dirt that is built up in it.

Received my bolt a couple of weeks ago and went to install it yesterday. Ran into a snag. The part the bolt is actually screwed into that is shaped like an arch, it happens to be stuck and won't move. i have it out of the jeep and put two vice grips and still unable to twist it out. I'm going to have a bolt or metal rod welded to the screw tonight and hopefully get it out. Assuming i can't get it out does anyone know where to find that piece?
