im needing to repair a timing belt mount that was stripped when i impacted the bolt in. its a bottom bolt timing belt side engine mount. okay i looked at the hole.
i have the heli coil kit.

my problem is how do i install the heli coil. does the heli coil have to be all the way bottom out inside. when installed?


ive looked on you tube looks straight forward but the question im more concerned is the thread hole???

the thread hole ive seen a guy on youtube says he put it till it bottoms out.
then another guy says he installed the heli coil flush. so im confused.

ok what if i install the heli coil just flush but it doesn't bottom out all the way inside.

only one heli coil thread..
and most videos they just use only one heli coil. the thread on the bolt i assume threads all the way in the hole???

do i have to install like two heli coils??? do i need to fill the whole hole with heli coils???
or does just one heli coil good enough???

the hole looks longer than only one heli coil.
sorry for alot of questions i just want to find out really how to install heli coils this is my first time.
confuses me...

do i need to double up heli coils? or one is enough.
install it flush with outer hole or install it all the way in.


help anyone ever did this...

 

Pics? I just had issues with some brembo calipers and went with safe certs instead of helicoils. But pics would help.

 

When i used TimeSerts, i ran them according to directions. Loctite on the stud held it in just fine.

 

X2 Timecert is the only way to go period.

 

In response to your question of using two helicoils... You should really only use one. if you put two in and hit the first with the second coil, you run a really good risk of messing up the threads and find yourself in even bigger trouble than you originally had. Your helicoil kit should have come with different length coils (to use for deeper bolt applications or ones that require more torque.) Check the torque specs for the bolt your looking at repairing the threads for, you may be able to get away with one helicoil depending on the size. Pics would help.

Good luck!

 

I've repaired a lot of threads, so I will share my opinion.

Is it really a 'Helicoil' or is it a thread repair insert like this one?:



If it is anything like the above, you only need one. If you thread two in there, the end tab would overlap into the next insert and the bolt would not progress.

The way these work is through expansion and friction. When you thread the bolt, the insert expands into the threads you tap before adding the insert. Tightening the bolt multiplies the strength. In fact, thread inserts are often much stronger than original aluminum threading, even if the insert is only 1/3 the depth of the original.
