The tab at the first helicoil wont break because its so close to the bottom... I tried and i cant knock it through[/QUOTE]

How will this break then? Will i need to put a flat thin screw driver down the hole and try knock it at the bottom side to side for it to snap? cant think of any other way.

Its hard because the holes so shallow as well.


So many problems and issues with this build, i was going to stop but now i just need to get it done whatever it takes,

I installed two of the helicoils on top of each other

Im afriad that it is not as simple as installing the heliocoil and being good to-go and fix the bike.

So, when i had the helicoil out, it fits snug around the bolt and screws on.

I threaded the hole with the taper took down to the bottom and then installed the helicoils.

DEZPERADO Are there threads in the hole already? I suspect that the hole already had a helicoil in and came out when the original bolts were removed.

Try the bolt in the Helicoil first. If it fits then try the Tap in the hole and see if it will cut threads.[/QUOTE]
