Forks helicoils?

(1/3) > >>

Hi
I bought a set of forks recently that had been fully rebuilt.
New stanchions, seals, sliders all polished.
They looked good so I thought why not.

It now seems that the threads  on the sliders which hold the mudguard and top of the caliper are bugggered.
The guy I bought them from has offered to fit them with helicoils.

Can't say I'm convinced and my initial reaction just to tell him to do one and get a refund.

What do you think? Any advice welcome.

Picture below shows the threads in question -
I'm thinking this is already a weak area and drilling would weaken it further - am I right or wrong?

These are not the actual forks - just a picture I grabbed from the net

Trigger:
No problem in helicoiling those holes. As long as it is just the threads that have stripped and there are on remaining bits of bolt left inside. Check for any hairline cracks because the coil will just spread this out.

Bryanj:
I agree, no problem at all with those, done them many times

hunterso:
Ok great - thanks for that chaps

Doc.:
Helicoils are technically better than the original threaded holes.
You're spreading the load over more area (like having a larger diameter bolt), and you're not wearing the threads in the Forks each time you remove/refit the Bolts.

If all vehicle makers weren't so 'penny-pinching', they'd fit them in the first place  ::)
