anyone used a Time Sert to repair a stripped spark plug hole

[No Cents]

If it weren't for bad luck...I guess I'd have none. I pulled the front plug out of the 117"er tonight to see how they looked...but out came about half the threads with it...damn the luck.
I order the Time Sert spark plug repair kit part# 4212, and some inserts part# 42125...which are M12 X 1.25 X 17.5mm.
I went ahead and pulled the front head off, and I have it on the work bench ready for the fix. I might go ahead and pull the back head off too beings I have it down this far and do them both and be done with it.
Does this sound like the best way to fix a stripped spark plug hole with a Time Sert vs a Heli Coil?

It would be my choice. Some might not agree.

my choice as well and I'd also do both heads

  Repaired many stripped plugs with Timeserts. Used to blow plugs out of VW heads quite often.
Never had a problem with them.
  Used a Helicoil one time.  It backed out.

[DanThe Man]

I've done and it worked well. Stock 88

[RevFastEddy]

Both will work but Timesert (sp) is the better choice.....    Best choice could be weld it in and re tap like new....


I guess from now on using a little never seize and a torque wrench will be used. Plus remove plugs when cool.    Best of luck...

  Time serts done correctly are a permanant fix you should have no issues,follow the directions and take your time.

Thanks for the replies men. I did have never sieze on the plug (I always use it)...and the bike was cold. I'm going to go ahead and do both heads and be done with it. The Time Sert looked like a better choice to me over the Heli Coil for a permanent fix. I have never used the Time Sert before...so this is treading new waters for me.
I guess I just needed to tear the top end off it one more time

no cents! the rear plug in my 2005 eglide has me worried because it's tight threading in and  out.asked my local service tech about the options and he highly recommended the time sert method.said he's used them for years and never had a problem and they can be installed without removing the head.

[chuck the wrench]

I have used them in my EVO and they work well, tried other apps. which all failed, even had to make a time cert of my own and still holding up. My number one choice.

With the head off I would check the depth of the spark plug into the combustion chamber...
If any of the threads of the plug are into the chamber they will carbon up... and that will strip-out the aluminium threads. Also check the depth compared to the Timesert, most are steel (copper coated) if there is protrusion then I  like to used the aluminium ones

I used this on the last one I did, worked great.

Still keep the tq wrench set to the low side because the AS acts as a lube and can gi e a false reading.

[wfolarry]

How does a lube cause a torque wrench to give a false reading?

[Ancient]

Yeah, I wouldn't call it a false reading either. The wrench doesn't know if the threads are lubed or not.

But that being said, in the airplane building business, we do have 2 separate torque spec's for dry and lubed fasteners.

[rbabos]

Wrench don't know the difference. It should have been mentioned the set torque will increase the pressure on the threads with lube,  similar to an overtorque condition. Torque value in the book is for dry fit.

Ray, be sure to dab the threads with anti-sieze

Yes, they are cool also.

I've never had to use a time sert but understand how they work but I have a question.  What keeps/holds them in place?  I can see them coming out with a spark plug when changing plugs without something holding it in place.

Well technically you don't know how they work..

Good link Max - Thank you.  It was the final part of the process that 'locks' the time sert into the hole.  That was the part that I did not understand.

Failing that and if internal leveling is needed after within the chamber red loctite is more than up to the task to seal and retain the insert. Head gets hot but not enough to degrade it.

If you want it to never come out, use the green Loctite - sleeve & bearing retainer.
