Timesert Failure

OK, so a while back I did the unthinkable and stripped out the oil drain bolt on the left side case on my '06 450. (The one under the ignition cover). I repaired the drain with a timesert. Untill yesterday it had performed flawlessly. When I went to do an oil chnage last night I loosened the drain bolt and noticed when I removed it that it had something just under the copper washer on the bolt. After a bit of looking I determined it was the shoulder on the timesert and the first thread. Apparently what happened is the timesert fractured and left about five threads in the side case and the top portion stayed on the bolt.

Has anyone had this happen? If so how did you get the remainder of the insert out. I can replace the insert I am just looking for suggestions as to how to get the insert out....:thumbsup:

Thanks

I would try a screw extractor ("easy-out") first.

was the timesert installed using something like permatex or just put in as is?

If it was put in as is, I'd clean hte hole up, put permatex on the oil drain bolt, let it set up, remove it, (it should pull the timesert right out with it), and get a new timesert and drain plug.

I figured I would try that this evening. The only thing that concerns me is the design of the timesert. If I understand it correctly when it is installed with the tool it deforms the last couple of threads (deepest in the hole) so that it "bites" so to speak, into the aluminum housing. My concern is that if the screw extractor does not work I have now damaged what is left of the insert. At that point I am committed, and my be down a road I do not want to go down.....

I have never heard of a timesert failing. Did you go to the timesert page to see if they explain how to remove one?

If you used a timesert you are correct that when it is installed the "setting" tool flares out the last couple of threads. If you used loctite to put it in like your supposed to, A screw extractor will take it out.....with a little heat. I have had to remove them before and thats what worked for me. I would try that and then put a new one in.

I have removed heli-coils using a pick and needle nose pliers. I used the pick and got under the heli-coil enough to grab it with the pliers and then twisted (counterclockwise) and pulled. They came out very easy and did not damage the aluminum parts.

I have never used timeserts though.

The real question is why did it fracture....I have never seen one do this before
