  • Mirror, mirror on the wall

    You know how sometimes a simple five minute project turns into a nightmare, well that just happened to me. I was going to swap out the stock mirrors for a set of candy drop LED turn signal mirrors yesterday and that failed catastrophically when I managed to twist off both mirror stems leaving the just the stud embedded in the mount. Knowing beforehand this was a possibility I took every precaution starting out with penetrating fluid and heat to loosen things up. I was a little hazy on which one has the right hand thread and which one the left, so my first step was to gently rock the stem in each direction to give the penetrating fluid a chance to get down into the thread. For the next hour or two I alternated between heat and penetrating fluid and seemed to be making some slight progress as I was getting about a 1/16 turn on the stems and it appeared as though the stem was in fact turning. Then it happened! At first one and then the other one twisted off leaving me with a mirror in hand and a broken stud in the mount....damn. So, now I have to go through the whole process of drilling and easy outs and possibly re tapping the threads to get back to normal. Before I start I wanted to get a definitive read out from someone on which mirror is right and which is left handed thread since it makes a difference on how I tackle each one.

    Easy to remember. The mirrors are designed to loosen in case they strike something in a forward motion. Left mirror would spin CCW and the right one will spin CW to loosen.

    So, to summarize, it’s the right mirror that has the reverse (left hand) threads.

      With the mirror stems gone, the light of day, a fresh perspective and a cup of coffee I was able to deduce exactly that. Sadly, with more heat, more penetrating fluid and an ez-out they aren't budging one bit. If I apply any more torque I'll probably snap the ez-out off in the hole, so it's time to consider my next move. I'm thinking of drilling out as much of the stud as I can and then peel out what's left. Going this route is a giant pain in the ass, but I'm not sure I have any other options. Suggestions anyone?

        Center punch and start with a tiny bit and incrementally increase size of bit.

        Yep, did that.

      Once the easy out is tapped in with a hammer I usually give it one or two final decent whacks to ‘shock’ the crud built up on the threads into submission.

        If you use an easy out....
        Use a square shaft easy out NOT the spiral type. The square ones do not break as easily.

            Well it was a long drawn out process, but I finally managed to install the mirrors. Since no part of the stud would come out...not even a little bit I was forced to drill out the whole thing and re-tap the hole. What a giant pain in the ass this five minute project turned into! Oh and to make it even more fun my clutch system either has air in it, or I screwed up the master cylinder...whoopi !

              Turned out to be an easy fix. I simply loosened up the clamp and raised the master cylinder making it the high point in the system. A couple of squeezes of the handle and it bled itself out in a few seconds.

              I've actually been talking about my Roadliner, not the Road Star...lol. Sorry for any confusion.

            Wow...I changed mirrors about a month ago. 5 minute job. Guess I got lucky 'cause shit like that is usually exactly what happens to me.

              I'm curious as to where he found a left-hand tap1

                You're kidding right? I bet there's not a left handed 10mm 1.25 thread tap anywhere within a 1000 miles of me, never mind the fact that it was a Sunday....lol. No sir, as much as I hated to do it I re-tapped that side using the same right hand tap I had and used the optional right hand adapter provided with the mirrors.

              I didn't know about any adapters. (I've never changed mirrors, outside of installing bar-end mirrors on my CB400F and car-style mirrors on my Rabid Transit fairing on my CB900F).
