    Helicoil or Time-Sert

    Well after 503,000 miles and 145 oil changes I stripped the threads in one of the oilfilter cover holes in the engine block.

    I know it's a 6X1mm thread but I don't know if I should use a Helicoil or Time-Sert
    to repair the thread.

    Has anyone done this repair?

    It's the hole that is the most facing the back of the bike which is the easiest to get at. Can still do it in the frame, I think?

    Anybody, anybody?

    The lower front hole stripped on mine a couple of years ago.

    With the engine still in the frame I was able to "delicately" drill out the hole and insert a Helicoil. It continues to be secure and working just fine today.
    I used Helicoil because I have used them for many years and they have always worked for me, when done properly.

    I have never used a Time-sert, a lot of people have and say they are superior to Helicoils.
    Maybe I'll try Time-sert the next time the need arises.

    If this is your first time for placing a Helicoil
    take your time
    measure depth
    get comfortable
    use good bit
    drill straight
    remember the engine block is "soft"
    read the instructions
    There's probably a "How to" video on Youtube to watch?


    Good Luck with the repair.

    There are a number of brands of thread inserts & they vary in material,length,thickness and so on. It really is beyond brand choice at times & based on who has what gets you going if in a road breakdown or what fits into the repair area size/material wise. I often lean toward the "serts" as they don't really need an insert tool for each size as do helicoils but still, its not so much which is the best product as the one that works for the situation. Places like Fastenall often have a high delivery fee attached to getting one small piece so look around the net or retail wholesale scene for various sources.

    Another comment, if it is your first time; find a piece of material, an old casting, etc, and practice. The kit should come with enough inserts so you can waste one or two practicing.

    As far as which one; IÔÇÖve only used Helicoil; so, IÔÇÖm no help selecting which one to use.

    Good luck.

    stripped bolt

    Why don't you tap it for an 8mm bolt?

    Good idea, going to talk to Jim fretz to see what he would do.

    Not having done one of these (knock on wood!), what's the difference between doing a helicoil/timesert versus tapping to 8mm? My point is to do a process which gives you options or do the one thing that is "less destructive" first. Does tapping to 8mm preclude doing a standard helicoil or that you have to go to the next higher size helicoil? What if you do a helicoil/timesert first and if that doesn't work, can you then go to 8mm after that? I'm just wondering if there's a good order to these types of repairs?
