My son has been driving the .034 the last few weeks, and tonight he sent me a text from his buddy's house and said that he heard what sounded like belt squeal as he pulled in to park there. I tried to get more info out of him, but it was pretty pointless as he was otherwise engaged.
So when he got home, he pulled it into the garage and popped the hood. I could hear the noise he was talking about, and it didn't sound like belt noise. It sounded like a bearing grinding.
I open the hood and see that the PS reservoir is vibrating like mad Had him shut it off immediately.
I grab the reservoir and it felt loose. I can move it about a quarter of an inch back and forth, but it's not the only thing moving! The whole PS bracket is moving!
When I started digging into it, I found that the two hex head bolts that go in from the back of the bracket had sheared off, and the socket cap screw that goes in from the front was loose. I disconnected the return and pressure lines (which were fun to break loose with the whole thing just flopping around!) and pulled the whole bracket and PS pump out of the car. I found that there is still some of the socket cap screw still in the head (it was only threaded in about 4 threads apparently...either that, or it broke 4 threads deep in the hole?) and the sheared off hex bolt threads are still in the bracket. I have no idea how it stayed where it was or how the belt stayed on...
So I'm wondering...does anybody know the length of these three bolts so I can replace them?
I'm pretty sure I can get the broken bits out of the bracket, because I can take it to work and chuck it up in the Bridgeport mill, but any tips on getting the broken bolt out of the head? I've never had much luck hand drilling and using easy-outs...
Lastly, WHY would this happen? In 25 years of wrenching on all sorts of cars, I've never seen anything like it! The bolts aren't corroded much at all, and the breaks look fresh. I can't believe some sudden load on the pump would have caused it. Wouldn't the belt have slipped before that?
