Use vice grips if possible, and heat. Small raps with a hammer on the metal not the porcelin. Good Luck. Another method which eliminates a lot of stress is to break off the porcelain and remove it and the center electrode (they come out together after you break the porcelain all the way around), then use an Easy Out (screw extractor) to remove the rest of the plug. This method only takes a few minutes and saves busted knuckles and a lot of cussing. LOL or you can get a smaller socket that will almost fit and beat it on with a hammer
The knuckle could be heli-coiled if the damage is not too bad. If the stripped threads are on the caliper, replace the caliper.
If the sensor is stripped you will have to replace it. If the fitting or hole it threads into is stripped it is likely you can make oversize threads and use a fitting called a bushing to repair it. Mind you I got desperate one night and epoxied one in. Its still working but if I ever have to change it I am toast.
If the threads of the sensor are stripped, it must be replaced. When this happens, the threads on the exhaust are usually also damaged. These can be repaired by "chasing" them with the appropriately sized tap. Be sure to use high temp. anti-seize on the new sensor. Sensors should only be removed when the exhaust system is at operating temperature.
You might try to use krol as this oil can creep into the smallest cracks to help loosen the spark plug. http://www.kanolabs.com/ The next problem will be the threads probably will be stripped. Use a Time-Sert insert to repair the stripped threads. http://www.timesert.com/html/sparkplug.html http://www.timesert.com Good luck!
Threads are stripped or bearing is disintegrating.
No way to fix that - your tank is scrap.
The threads are what make it work. As you will know if you have tried to use a screw with stripped threads, it is useless. That is because a screw is a simple machine built from an even simpler machine: the inclined plane. The threads are an inclined plane wound around the outside of the screw, and are what change the twisting motion into a lifting motion.
Could be that the threads are stripped on the plug or the head where the plug is screwed in. Or maybe it's the wrong plug..
Re-tap the holes (cut new threades) Use the TIme-Sert thread repair system will repair the pan.http://www.timesert.com Use a oil drain valve to replace your oil drain plug in order to prevent the threads from being stripped. www.qwikvalve.com
sounds like you have stripped the threads, if so you need a " heli coil " thread repair..and follow directions. those threads will need to be repaired or retapped,and always start the threads on your spark plugs by hand and not with a wrench.
If the screw is stripped then the threads are not holding and can be removed with pliers. If your asking, about the head being stripped, then you take a hack saw blade and cut a new slot in it,this way you can use a slotted screw driver to remove it. If it is locked in and does not come out, you will have to drill it out with a drill bit that is smaller then the thread size.
If the threads on the drain plug are stripped and the pan threads are good, you can just replace the drain plug. More often though, the threads in the oil pan that the drain plug screws into are what get stripped. If it's the oil pan, there are still a number of pretty simple options: There are oversized plugs you can buy, rethreading kits with inserts or self-tapping plugs. And there are rubber expanding plugs that are almost foolproof. It is your choice as to how you want to fix it. Go to your local auto parts store and look at your options. Whatever you do, do not use a silicone sealer to fix it.
If you have stripped the head of a head bolt you will need to either obtain a special socket that grabs stripped bolt heads (Craftsman makes one), or you will need to drill the center out of the bolt and insert an "easy out." The second option is extremely difficult. Your third option, if you are very accurate and surgically precise would be to drill the bolt to only the inside diameter of the threads. This will cut the threads of the bolt off into the threads of the hole. Then you can use a tap to clear the threads, being very careful not to allow any metal shavings to fall into the engine.
Not aligning the threads up correctly and forcing the lug nut onto the wheel stud will strip the lug nut.
It more than likely needs a Heli-coil where the spark plug screws in. The threads are probably worn out or stripped.
drill screw head out with 1/4 " drillbit mirror mounting plate can be removed by removing door panel. replace with new monting plate if threads are stripped in mounting plate. just did this myself
== == Because they weren't tightened at installation properly. Because the threads in the head are stripped.
Propane does not go bad. Propane tanks have a shelf life. Valve threads sometines get stripped through careless cross threading.
The bolt on the tensioner pulley are opposite of a standard thread. That is, righty loosey lefty tighty. I know this first hand because I stripped the threads on my pulley trying to remove it on my 94 Sub.
The filter may not have been attached properly, the threads on the engine side of the connection may be stripped.
Did you strip the actual plug is rounded off or did you strip the plug threads? If you stripped the plug itself and can get to it use vise grips. If you cannot get to the plug then go to your local parts store and tell then what happened. I know Snap On makes a special socket to remove rounded off bolts and spark plugs. Now if you actually stripped the spark plug threads then you may be able to just chase the old threads with a tap and clean them up enough that you can insert a new plug. Use anti-sieze compound and do not over tighten. 13 ft/lbs and no more. If that is not possible you will have to purchase a Helicoil. You local parts store can sell you the correct size and tell you how to use it.
You have a few options. I it is not stripped just replace the gasket. If the threads are stripped or cross threaded, you need to have it repaired at a welding shop. They can easily fix this problem. Purchase a new drain plug and seek out a good shop.
Try removing the bolt, you may have overtightened or stripped the threads, another reason would be that your pins have been installed in the wrong order
YOU COULD USE JB WELD,ANY AUTO STORE SHOULD HAVE IT. OR YOU COULD USE A KEENSERT,THIS HAS THREADS ON THE INSIDE AND OUTSIDE.YOU WOULD HAVE TO DRILL AND TAP THE STRIPPED HOLE AND SCREW IN THE KEENSERT.THE INSIDE THREAD HAS TO BE THE SAME SIZE AS THE HOSE END, KEENSERTS ARE ALSO MADE WITH A THIN WALL, WHERE LACK OF METAL RESTRICTS THE SIZE OF THREADS. GOOD LUCK PAUL G
To remove a pressed-in stud, you usually stack up a few washers and crank the stud out with an impact wrench on the nut. If the threads are completely stripped all the way down, you may have to take the head to a machine shop and have the stud drilled out and tapped for a screw-in stud.
