an update on that sheared tensioner pulley stud

[SuperHO]

So far, It's just been too damn hot to even open the hood. So the car has set for a month or two. Then, the other morning, an epiphany struck.

What if I were to build an aluminum bracket so I can use the mounting hole for the ATX timing tensioner and place the pulley in the right spot? Does that make sense at all? I guess sort of like Jose's shifter boss doohickey. Thoughts on this?

Why can't the stud just be replaced with a bolt?

it could, but a bolt will break off the same way a stud does

Use a Grade 8 or better stud

Had a similar problem when I replaced my 3.0 with a 3.2 motor. i switched everything over to the 3.2 long block to make it look factory. I even drilled and tapped holes in the bosses for the 3.0 brackets. Worked great.

The one issue I had was that I could not remove this tensioner stud. So I made one.

Check the diameter of the stud. Go to the hardware store and get a metric high strength long shank bold. Cut off the threads and use the shank also cut to the necessary length. I made mine 1/16 longer and pounded it into the hole with a hammer to about the same depth as the stud in the old 3.o block.

No more issues and is plenty strong.

HAd this happen to me.

Right angle drill, hardened drill bit and a decent extractor did the trick. Took about 2 hours is painstakingly slowly drilling and then turning. The trick is the same with valve cover studs. Slow and constant force.

whatever you do, good luck.
