Heli coil needed ...

The Buddha · January 16, 2005, 04:24:06 PM

Yea I stripped the cam tower threads that hold the valve cover on ...
OK and the real problem is this ... I am too cheap to buy the helicoil kits ... costs like $30 ... and it has like 10 ... I need just 1 helicoil thing ... I have the drills and tap ... OK would need to know what tap and drill to use as well ... but if anyone can spare 1 of those little helicoil things ... I'll pay for it and shipping of course.
Cool.

What size is it? I have a few kits from my Bultaco rebuild.

The Buddha · January 16, 2005, 09:19:08 PM

Its the valve cover bolts ... its not M6 X 1.0 ... maybe M7 X 1.0 or whatever. I should check the stores here first.
Cool.

Why don't you drill out the old thread and tap it for a larger bolt? Use a washer and put some sealant on it. I have a head that this has been done to and it works just fine.

The Buddha · January 17, 2005, 09:40:36 AM

OK then what bolt do you use ... the bolt has O rings that go under its head that are about dime sized ... a washer would work if its larger than a dime ... However I like having the steel threads ... looks like its gonna be a even cost either way now ... especially if I find 1 heli coil like I want to.
Cool.

Not sure the size of the bolt used, one size larger than stock. Basically all that was needed was to run a drill bit to clean out the rest of the stripped thread and then tap the new hole. The problem is that the bolt will not have the shoulder on it and risks over torqueing. Installing a heli coil is still the best way.

ok, 7mm x 1.0. I'll go look in the garage.

Hey man,

Don't know if you still need it but...

I have a 7mm x 1.0 kit. Let me know if you want to borrow it.

Later.

The Buddha · January 21, 2005, 02:09:29 PM

hey lemme look in my local tool store ... shipping it up here and back could be more $$$ :x ... I believe I should be able to get just the thread things and should be fine ...
Cool.
