Helio -Coil
Can Helio - coil be inserted without removing the tire and tube?

Re: Helio -Coil
In a wheel for the cover? If you drill through the rim the wheel would be toast any way, but much easier to do on a bench. One of my wheels has been drilled and tapped for a size up, which while a pain is simpler. I think it may be a bit shalllow for a heli-coil anyway?

You can shorten heli-coils. You just want a couple coils to hold. We use them a lot.

Re: Helio -Coil
I like Pete’s advice here:
Looking online for epoxies to use for thread repair I’ve seen mixed reviews ... but wouldn’t hurt to try.pdb wrote:Just a heads up. I went into our local aviation parts store, found a new Cleveland wheel and bought a number of the machine screws that fitted perfectly and were the correct match. At the field I took the new screws out and discovered that the previous owner (>20years ago) had already drilled out and retapped my wheels to the next size up. Now those threads are mostly stripped.
I was given one word of caution about the use of helicoils worth considering. A steel helicoil in a magnesium wheel presents the potential for corrosion as a result of the contact between dissimilar metals.
I still haven't fixed my wheels and I am now leaning towards cleaning out the holes, filling with JB Weld, and retapping.

Re: Helio -Coil
One unauthorised repair that I have seen on a rim that has been drilled all the way through when going up a size on the hub cap attachment screws was the repair was carried out with heli-coils and then the area was filled with PRC1422 and the screw was inserted with grease on it so the PRC doesn’t stick to the screw.
