    I made a similar video 18yrs ago but, it was done to a CB1100F cam chain tensioner bolt hole.
    Most of my videos were deleted because they were not child friendly, oh well.
    I swear by the Time-Sert thread repair method, it is the best.
    Keep up the good work

    These videos are going to be a wealth of knowledge for years to come as more and more of these bikes are having the same issues, or being brought back to life. My CB1000C appreciates it.

    Hey Spud, good job!
    Nice job of using the search engine on the site and figuring it all out!
    A couple of notes...
    1. Your countersink is not deep enough. The surface where the locknut seats needs to be flat.
    2. Do not modify the bolt, as the o-ring seats against that surface where the size changes, as well as the flat area.
    Changing any of that could result in a leak to someone that doesn't understand this as well as you do.

      Thanks Gene! I would not have been able to fix it without the info I found on the cb750c.com site. Regarding your notes:
      1. I agree regarding depth and have no idea why it would not work out. As noted in the video, I even used a power drill on it several times and no further chips were produced. And I contemplated pulling the insert out and trying again but decided against it. The top surface does need to be flat, however, the top of the insert has a quite wide flange on it which satisfies this IMO. Ideally, it should have been flush without a doubt.
      2. It appears to me that the O-ring does not seat at the size change as stated, rather, it seats on the upper portion (larger) of the shaft and the jam nut. Making a modification of some kind is not an option as far as I can tell. I gave two options in the video, one to add a shim and the other to modify the bolt (and associated risks). The biggest thing I learned out of this repair is that the insert does not properly duplicate the form factor of the original design (a thread at the bottom of a bored hole, the bored hole being relief for the larger shank). The insert has a minimal amount of relief, so you have to account for it in some way. I think the animation I created is correct and shows this relationship, but I could be wrong too.
      BTW, I have no leaks.
      I really appreciate the feedback and hopefully people read the UA-cam comments (I know I do) as these kinds of clarifications and suggestions come up all the time.
