while removing the harmonic balancer a piece of the removal tool broke off inside of the crank?

Question

while removing the harmonic balancer a piece of the removal tool broke off inside of the crank. It broke off in the hole where the crank bolt go, it broke off enough to where you can get a pair of needle nose pliers on it, but it will not back out. Do you think I can drive this vehicle for a little while in this condition without the pully coming off, and if not how can I repair this problem. I was thinking of putting a torch on the crank and getting it hot enough to pull the piece out, would you recommend this.

Answer 1

drill it out with a bit big enough to get a grease fitting to thread into it,put your grease gun on it and it will push it out like a hydraulic press. I know this sounds stupid but it works.

Answer 2

What probably happened is that a part of the reamer used to clean and shape the root canal was broken off within the root of the tooth. (Not the jaw itself.) This is not an uncommon event but it frequently means that the root canal treatment can't be completed as the broken instrument is now wedged in the canal and blocks the dentist's ability to seal the canal properly. As such, the infection will never clear and the tooth must ultimately be removed. In rare cases, the broken instrument manages to seal the root completely and the tooth can be kept. In any event, the dentist should have explained all this to you. Regarding a lawsuit: It is best to first go back to the dentist who did the root canal and give him a chance to do the right thing. (i.e., if he actually did make a mistake, see if he will pay to have the tooth replaced.) Have him explain in detail what happened and give his side of the story. If you are still not satisfied, contact the local dental society and request a peer review hearing or mediation. No lawyers are involved so you have no fees to pay and any settlement is all yours. This process also results in a much faster resolution to the case. Some final considerations: did an endodontist or a general dentist do the root canal? (You have a better case if a general dentist tried to do the root canal.) Did you sign an informed consent agreement? (i.e., were you given a list of possible negative effects which included an instrument breaking?) If so, it is much more difficult to sue. Why were you traumatized? Were you so nervous as to make it difficult for the dentist to work on you? You "just wanted to get out of there": are you sure the dentist didn't explain the situation thoroughly and it just didn't register with you? Did the same dentist who did the root canal also pull the tooth or was another dentist involved? If there is another dentist involved, what is his/her opinion of the situation and will he/she put it in writing? I hope this helps.

Answer 3

I've had this happen to me. On some vehicles, the balancer is pressed on with the crank shaft bolt locking the balancer in position on the key way. I used a special type socket that was slightly larger then the crank shaft and had a taper on the shoulder and a 1/4 hole on the opposite end to accept a drill bit. The tapered part was laid flush with the crank shaft hole and dead centered and I proceeded to drill a hole in the piece broken in the shaft (once a starter hole is made, a larger bit can be used to enlarge the hole) and used an easy out to remove the broken piece. The radiator may have to be pulled to avoid penetrating the core.

Answer 4

Do not drive the car, it will just end up sending the balancer and possibly the fan as well through your radiator. Do not heat the crank with a torch, you will take the temper out, and ruin the crank and the front seal.
To get the part out you can use several methods. First, spray with penetrating oil, then try good size vise-grips and a hammer to tap on them with. If no luck try a stud remover and a prybar, to turn it and pull at the same time. If can't get a grip on it with those tools, another option is a drill chuck. Lock the chuck itself on the part and try the prybar/hammer. The last option is to actually drill out the part, being very careful to stay centered and not damage the threads in the crank.
A few ideas, and good luck!

Answer 5

1: Don't drive it, the balancer will come off.
2: Do not use a torch on it for heat. Heat will change the steel and you will damage other parts. NO HEAT!!!!
3: You will have to try to carefully drill out the piece and then use an easy out to remove it.
What piece did you break? The puller is suppose to have a round disc for the draw screw to push against and not damage the crank. OOOPS

Answer 6

try using a small chisel to break it loose. problem is you probably messed up the threads for the bolt that goes in the hole. were you using the center attachment on the end of the puller? be care full using a torch. if you get the end of the crank to hot you could melt the front seal of the engine. then you will have additionall problems. good luck

Answer 7

Drill a hole in the center of the broken bolt and use a screw extractor or easy-out to remove it. You could try to weld a smaller bolt to it if you have access to a welder or have a portable welding company come and do it. Pulley may or may not come off---the large bolt is just there to keep the balancer from coming off....check it every day if you don't get the bolt part out and use it like that.

Answer 8

try drilling a hole in the piece and running a long self threading screw into it and prying it out that way

Answer 9

NOpe. Machine shop job. Let them do it. It will be their cost if they f***it up. It has to come out.

Answer 10

dont drive it yes put heat to it
