Good news and bad news
« on: June 23, 2010, 08:26:37 PM »
I managed to install both the missing frost plugs in the 175 block. That is the good news. Unfortunately my engine hoist hydralic ram wouldnt hold things in place while I removed the engine mount so that made it more of a challenge. Despite blocking both under the engine and hoist arm I had to continually pump the thing back up. Things were actually going good tonight, getting close to being done in about 1/2 the time it took me to do the first one, then I broke motor mount bolt off in the block. @!#%  >:(I think with the hoist contiunally losing its holding capability, it sank and put all kinds of pressure on the bolts as I ratcheted them in.
Needless to say I am not happy. Removed the mount again and was hopeful I'd be able to back it out by getting a vice grips in the 3/16" of bolt sticking out. No go. Looks like I am going to have to drill it out and that may require me to buy an angle drill. Maybe I can rent one? I really dont want to buy one.
I will be installing new "hardened" bolts once I recover from this.

I am not a welder, so I don't know if this will work....

I have heard of situations like this where a skilled welder can attach nut to broken bolt.  The bolt can then be extracted with a ratchet.  I think it depends on the types of metal too.  The welder can work on the bolt, but the weld will not tack on to the block.

HTH,

Right on the money. I've seen this done. I guess there needs to be access and clearance. Make sure you're well ventilated.

Thanks for the suggestions. I think it would be tough to weld onto that small of a stub sticking out but you did say "skilled" welder.
Tonight I bought a right angle attachment for my drill and will try to drill a pilot hole and get a screw extractor in there. If that fails, I'll  have to drill it out 100% then chase the threads with a tap.

Actually, it's not all that tough.  I have even done that, with a dock post though.  All yo need is enogh of an exposed thread to be able to start the nut on then you weld inside the nut.  In my case, welding the nut on even heated up the broken bolt enough to break the rusted bolt free with the heat from welding it up.

There wasnt even any thead on the bolt where it broke and if there was, it would be gone now from my feable attempts to remove it using a vise grips.

As long as a nut can go over it, it can be welded on. No need for threads. I've done it many times.

Hmm...many saying welding it would be the way to go. Maybe I need to look for a welder near by before I drill it out and really mess things up. Wire feed I assume?

I've seen it done. They actually sell special rod for this btw. Guy centered a nut over a busted off stud. Welded it on & a minute later cranked it out with a ratchet. Would never have believed it if I hadn't seen it with my own eyes.

Been there buddy, did that.  Drilled the broken bolt, then broke off the easy out and made the situation MUCH WORSE!  Those things are almost impossible to drill out, ended up pulling the head (it was a valve cover bolt) off the Barracuda and taking it to a machine shop for repairs. $$$

If there's any of the bolt sticking out welding usually works.

Very little sticking out...maybe 3/16", but maybe enough.

That would be a nightmare if I break the easyout. They are hardened so I can see why they'd be a (@!# to drill out. Man I should probably try the weld tactic.

No matter which 'extraction' method you choose. 'Member it always pays to saturate the offending broken bolt with PB Blaster, Liquid Wrench, WD40, etc for awhile. Don't be in a rush.

Easy Outs s*ck. Strong yeah but brittle. I've broken more than I can count. Y'know what's good for drilling out a busted off easyout? No BS. A good carbide ceramic tile/concrete drill bit. I sh*t you not it works!

But I'd at least attempt the weld the nut on scenario. I witnessed a guy do it & it worked like a charm. Remember to soak thoroughly beforehand ...

The only one worth using is PB Blaster, but when you weld it the bolt gets really hot, then you quench it with water and turn it out. No PB Blaster needed. Done lots of them.

I  never heard of it. Another new good thing to get... with endorsements.

OK I think I need to find a welder close by and try this becuase if I drill it out and mess it up then there will be nothing to weld too. However, if the welding doesnt work because the bolt is too short, I can still drill it out.
Now that I got the boat cleaned up, I hate to take it on the dirt roads! :-/
Oh well.

I drilled this out yesterday after picking up a right angle attatchment for my drill. NO FUN! Started small and worked my way up to a bit, just smaller then the minor diameter of the bolt that previously occupied that hole and hoped I was centered good enough not to totally trash the treads. Used oil to cool the bit and compressed air to clean out the chips every few minutes. Really went ok. Got lucky and had some sharp bits! Still ended up with a thin layer of the bolt in the hole though, but got most of that when I chased the threads with a tap numerous times. Its a little shallower then it was before but I went out and picked up new Grade 8 bolts a bit shorter. Still plenty of thread in there. Great to have that fiasco done.
Now, shall I admit that this was all due to some boneheadedness on my part? Guess others have fessed up being "dorkafide" at times.  :P
Yes I broke the bolt off because it bottomed out in the hole.  :-[Bolt too long you say? Get them mixed up? No. As I had mentioned before, (excuse time) my hoist kept lowering on me, so I was hurrying and stuck the bolts thru the engine mount but forgot that the bracket holding the slave solenoid shared 2 of the 3 bolts and it was laying in the bilge. THAT would have taken up the "extra" bolt sticking out that I was trying to crank into the block. DOH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Oh well. Cost me extra hours and a few bucks but it was avoidable! >:(

Don't feel too bad Ross, it happens to all of us from time to time.  The important thing (according to Dad) is to learn from our mistakes.   ;)  Glad to hear you got it straightened out!

Hmmm. Any time there is some bolt sticking out, and a vice grip won't do it, I take a cut off wheel and cut a slot in it.

Then, with a nice beefy fat flathead screw driver that fits the slot snug, and a crescent or wrench, try backing her out.

Just got one out last week this way.

Sometimes it works, sometimes not.

Depends on how much bolt is hangin out, and how tight that joker is.

PB is awesome. Nothing I've used compares.... though, I think Jim knows of some awesome stuff too, though I've never used it on threads.
