Replacing Helicoils

[SkiDaddy]

I have a used cylinder where all the head bolt holes have been helicoiled, and some are rotating when I go to tighten or remove the bolts.:banghead: What's the best insert to replace these (remember the holes are tapped for helicoils already). Timecerts?

Who has the best price on a kit?

TIA.:biggrin:

timecerts the only way to go

Timcerts for sure. I have used them many times on my kawis. But where to find a good kit I'm not sure.

Just talked to Paul, by the time I buy the kit & inserts it'll be a wash cost wise as compared to having him do it. :sneaky:

is the kit re-useable? just buy more timecerts next time, I'd buy the kit.

What is the difference with timeserts , I have helicoils and know how they work. are they that much better that i should buy them even though i have lots of helicoils.
Is a timesert a solid piece. Maybe it is similar to our keenserts at work accept the are steel. solid piece with 4 tabs on top to drive down and lock in
Yes/No

You can get the time sert in stainless steel for one. The other advantage is that they are a solid piece of metal not a coil like helicoils (a lot stronger IMHO). I bought a 6 mm and 8mm kit years ago and I use them all the time. One you make the initial investment the refill kits are pretty cheap

I was just wondering because I already have most sizes in helicoils.Are helicoils that much worse to warrant not using the even though I already have them

timeserts are way! better than helicoil

helicoils come stainless for one

i have never used a timesert so i can coment on them . i have never had a problem with helicoils. as long as they are installed right you never will.

i know a brand new t700 jet engine has helicoils all over it
