    You could certainly drill and tap the stripped hole for a Helicoil using a hand drill. Could you not get a Helicoil thread repair kit mailed to you?
    My further investigation of the Loctite and Permatex liquid thread repair revealed that on a 6mm bolt it is only capable of 23in/lbs. Hardly worth doing in my opinion.

    Team-
    I've been completely out of pocket @ Philmont for the last 2 wks and just now got back to civilization.

    That Stripped thread repair kit isn't the thing to ise on stripped metal inserts in a plastic tank.

    I'd use a suitable plastic adhesive in the stripped out hole, press the metal insert back in place, apply a very thin fulm of grease/release on the male threads, thread the fastener in the insert.

    Then give the fastener an eighth or quarter turn every 5 minutes until the adhesive hardens a bit.

    See post #604.

    Working off of my B berry I forgot to mention you'd have to clean out the stripped out hole, let evaporate, dispense a dab of resin into the hole, press in the metal insert, then do the other things I suggested.

    I didn't read the whole thread, too lazy.
    I have used regular J-B on engine side covers, no problem. Is there anything you can recommend for my on road repair kit that will seal a damaged engine cover that doesn't take 24 + hours to set?
    Thanks Dirty

    Metal Magic Steel Stick pn. 98853. I travel with half a stick and a few extra pairs of purple rubber gloves.

    This stuff also kept my buddies boat from sinking at the mouth of the MS river years back when he ran it up on a rock jetty and holed it so bad the bilge pump couldn't keep up.

    If you haven't already guessed it-I'mma believer.

    i have loose threads on a shock reservoir schrader valve - the thread clearance of the shrader external threads to the reservoir body is terrible - i tried teflon tape and it leaks down over time... you have a thread sealant that might work for loose fit threads? 577 maybe?

    i have motor mount bolts that loosen overtime. i was hoping to find a mechanical lock that works, but nothing seems to work..so maybe a chemical product will work... i have tried nord-lock and they still loosen overtime. i tried blue loctite, safety wire, double jam nut, nylock, split lock washers, and toothed lock washer (din 6797) and they still loosen. i have to retorque every 8 hours or so. is there a anti-vibration product that works? i really do not want to use red loctite, as i can't torque check them at all ...not like i need to - you can feel/hear when they loosen up and prevailing torque goes way down... ... and a couple times a year i pull the motor...it's a small 2 stroke, it doesn't feel like it vibes that much, but it is constantly loosening the mounts....

    577, 567PST, 565, or 545 all would be just fine to use on this application.

    We're dealing with small parts, so apply the product one thread back from the tip end of the threads on the schraeder valve, 360 degrees, smear it into the threads so that the thread trough if full and you see the crown of the threads on the schraeder valve so we don't run the risk of getting thread sealant into the shock internals.

    Let it sit overnight and you'll be Ace!

    A very good Loctite product that sticks things where most other things fail, is 480. A form of glue thats used to stick the studs into tyres fitted to ice race cars. Have succeeded in sticking rubber to plastic with it, and it seems to work on pretty much anything.

    I was thinking about your vibration issue with the 2 stroke. I have tried, with some success, to tailor fit the bolt/hole relationship. Having the bolt fit perfectly snug in the hole has helped stop the bolt from loosening.
    If you have the right sized reamer can you find a bolt slightly larger, then fit it with the reamer. Anyway, it worked on my old Triumph (not Henkley). The particular frequency of the vibration will have its own type of problem. That is to say; what works at one frequency may not work for another.
    Good luck.

    @dirty_sanchez....

    I am building an AR15 rifle and I'd like a recomendation for which loctite to use on the Gas Block screws. Most people say to use RockSet because it is good to 500 degrees. The forms say (I know, I know) that I want the equivalent of Loctite Blue but with temperature resistance to 500 degrees. The barrel gets pretty hot with sustained fire.....

    Any help would be great. Thanks....

    Some things are a dark science best left never to be fully understood.

    Good to hear you have it sorted though.

    Ride Safe.

    There has been some discussion (again) over on the DR650 thread in Thumpers about the failure of countershaft seals and two Loctite products have been mentioned to improve retention of the replacement seal. Note: Suzuki has designed a retainer and installed on 2013 models. Anyone who has had a cs seal failure would probably be installing the retainer along with the new seal.

    The two products that have been mentioned are 603 and 648. Would either of these products be preferable, or maybe something else would be recommended?

    Thank You! :clap

    GAThump-On the LC4 thread last night we were just talking about a weeping sight glass on the stator side of the engine-a very similar application.

    Here's what I responded:

    The sight glass on my '07 weeped just a bit but never enough for me to do anything about it.

    The rocker arm shafts where they exited the valve cover also were a place dust collected. A bead of 598 Black on the outside fixed this once and for all though.

    From what I understand that thing is fitted from the backside of the stator cover. You have to remove the stator cover, lay it on the work bench and push out the glass.

    I seem to remember the manual says to use a retaining compound as an adhesive to mount the glass. I'd come closer to smearing a bead of 518 or an oil safe RTV in the inner diameter (mating surface) of the sight glass hole which has been cleaned and degreased and dry before the replacement sight glass is gently pressed into place. I suppose any of the blue or red threadlockers would work as well though, but I'd use 518, 515, or 510 because of it's lubricity as the glass is pressed into place.

    If you choose 518 Gasket Eliminator you have the luxury of time-you're not rushed to reassemble (it'll never cure until you mate your parts), if you choose Instant Gasket, 598 Black, or 592 Blue the clock starts as soon as you smear on that bead. You need to press that glass into place within 3 to 5 minutes before it starts to skin over.

    This is yet another reason I like using Gasket Eliminators-I don't like to be rushed during reassembly. A rushed repair lends itself to a bad repair.
    ----------------

    Hope this helps.

    Shoot me a link to where the DR650 thread picks up the countershaft seal discussion and I'll jump in if you like.

    A little clarification: the seal itself isn't failing, oil pressure is pushing it out of its boss. :beer
