Re: Got problems, please help!!
Helicoils come in a kit, with oversize tap, inserting tool and helicoils.
You run the oversize tap in to the damaged thread, and use the inserting tool to insert the helicoil. The helicoil looks like a stainless steel spring.
I've had my helicoil kit for about 20 years, I have no idea how much they are these days, but a good investment if you like playing with old motor cycles/motorized bikes.
I'm sure the kits are available at most auto parts retailers.
