when removing the water pump from my 302 in my 91 truck. one of th ebolts broke off in the block I have tried everything I know to remove it nothing will work. what do you suggest I do.
When you say it broke off in the block, is there any of the bolt sticking out? If there is, you might have to pretty much remove everything from around there and vice grip it off! If its not sticking out of the block, damn, that can be a problem.
try to find a reverse drill bit. Might be enough to get it out if not you will at least have a hole you can stick an easy out in. Use the biggest easy out you can fit in the bolt. The smaller ones are way too easy to break off, Then you are in real trouble. Just go slowly and try heating the area up with a MAPP gas torch or something like that.
Good luck, Been there.
I think you are going to have to drill a hole on the broken bolt and use an easy out. Most auto parts places have easy out kits with the drills & the easy outs. It's not too hard to do as long as you have a straight in shot at it. If you haven't pulled the radiator, you probably will, and likely the grill too.
Do yourself a favor - use a corded drill - they have lots more power than cordless, and the regular chucks hold drill bits tighter than the hand tightened chucks. I have gotten lucky before and had the drill stick in the bolt. I reversed the drill and the broken stub came right out.
Best of luck
I have felt your pain my brother. All previous posts are correct.
They have many tools/gadgets for removing broken bolts available.
Having a smaller pilot hole for the reversed bits helps.
The key things to ALWAYS remember:
1. Take everything off that prevents a straight shot in with your drill
2. Save your time, money and effort and use GOOD and SHARP drill bits
4. Go slow and easy, you will be rewarded for your patience
3. Go straigth down the middle of the busted bolt
5. Increasing size of the drill bit each time helps (judgement based on size of broken bolt)
Hindsight is a wonderful thing, but I hope you soaked those suckers at least over night with a blast of PB.
Best of luck bro, we know you can do it. We've all been there.
Ouch...this could suck. Out of curiosity, how exactly did this happen??? Something like this is kinda hard to do without being careless, using cheap tools, using the wrong tool etc. etc.
My advice...try the easy things first. Try "hitting" it out with a punch. Position the punch so that when you hit it the bolt is being driven counterclockwise. If you have any bolt sticking out, then pipe wrench it out. If these 2 methods fail (I can get about half of them out this way), then try the easy out method. Worst case scenerio...dril, tap and heli-coil.
Do like Kell said ... and lube it with some PB Blaster or Liquid Wrench ... and make sure to use lube when drilling also. Been there ... Done that, Too .... on a 302 also.
I have not had good experience with PB Blaster. I know a bunch of people swear by it, but I had 2 cans and I threw them out. I've had much better luck with 3M Penetrating Fluid.
Consider yourself lucky it was only one. I have had good results with Kroil but most will work if you give them enough time. If you must drill invest in quality set of reverse bits. Soak with kroil or whatever and let set for 24 hours or more if you can. Get everything out of the way and be certain to drill on center! Start small and work up to as large as possible. Many times with the reverse drill bits the bolt will spin itself out. If not again use a quality extractor. A broken cheap easyout is a bear to remove. Good luck!
PB worked great for me on my stuck front discs on my VW ... didn't do too much on the fan clutch on the truck though, I will have to try the 3M stuff on that.
A broken expensive easyout that is too small to handle the torque is even harder to remove. Definitely drill on center ... and step up a size at a time until out or until the next size up may be too big to not cut the threads, then grab the easyout.
If you are going to use the ez out and drill method, CENTER PUNCH THE HOLE FIRST. This way it insures that you will get the drill to start straight and not screw up the threads for your new bolt. If it is sticking out, they have a tool called a stud remover. This works well if you have about an inch sticking out or more. If it is sticking out, but not that much, heat the area in the block around the broken bolt with atleast map gas, much better if you have access to an acetylene torch because normal propane torches will not get hot enough to expand the block in that specific area. While it is still hot, like red hot, use vice grips to remove the bolt. Should come right out like mine did on my 302.
All the previous is proof of paying the dues...Can you get at it with a welder? Mig or stick, but mig is easiest. You set a nut over the offending remenant, a nut like about two sizes too big, hold it in place and with the wire on the mig you "reach in" with enough heat to pool the bottom of the nut and the top of the bolt/stud together. The heat from the "weld" loosens the bolt and now you can turn it out with a wrench. Like all the others, patience is MOST important. Don't get in a hurry, let things cool, "work" it a bit... But you get to choose, good luck.
hey thanks for all yalls help what yall said about the cheap easy outs braking it broke so ive been trying my hardest to get it out. i love this truck and would hate to lose it like this plus i have bought alot of parts and almost redone the whole truck. has anybody ever had luck getting one of these easyouts out before.
Problem with the easyouts is that they are made of very hard steel that tends to break. If there is any of the easyout that you can get to you may get lucky and twist it out. remember to twist in the correct direction. Next you might try to drill it out. Again you will need top quality drill bits. Getting started is difficult. Most times the easy out has broken at an angle making it a bear to get your first hole started. I have forgotten where the bolt broke (water pump to the block) Check with a local machine shop and see if someone does house calls with an electronic disintergrator(sp?). If you can bring the part to them it will still be expensive but cheaper than the house call. They usually will charge by the inch of rod burned extracting your broken piece. One other option is to have a very,very good welder weld a nut to the broken stud and easy out. Good Luck
