Said bracket bolts to the frame, comes up behind the exhaust on the left side, and has a shaft protruding back toward the bike, on which the lever mounts -- this shaft is the pivot point.
The shaft is loose in the bracket, causing considerable play in the shifter. The bracket has not corroded, so it must be an alloy of some sort, or coated in some way. I could remove it and weld the shaft in place, but would like to know if a 6010 mild steel rod will weld this stuff, then what to do to protect it from corrosion if the answer is yes.
Does anyone have experience to comment on this?

Well :D did you just expect me to sit just here and keep quite, don't answer that :D..
6010 and 6011 are not a good choice for that application, these rods tend to crack under constant movement and vibration, my personal choice would be 7018 low hydrogen higher tensile strength and less subject stress cracks.
Thanks for your reply, Charles.
I have some "low hydrogen" rod -- 7018, I believe, or maybe 7010. Clearly superior welds, but tougher to run, and this is a tough spot to weld.
The bigger question is whether this bracket is some alloy that needs some different rod altogether.
On the "outside" of the bracket, where the chrome plated piece bolts on, someone has ground something off, as I can see bare metal, and the grind marks. I have no idea what was there, but if it sticks out at all, the chrome plated piece will not fit, so I understand the reason it was ground off. I think perhaps this was someone's inadequate repair after the original shaft broke. They may have drilled it and put the shaft in place. It has a hole in the inside end that a cotter pin is placed through to hold the shifter in place. The spacer he used was a lock washer -- clearly not original in any sense.
There is no corrosion on the part that has been ground off, although I am not sure if it would get wet, being under the outside chrome plated bracket, that fits pretty tight. While I have gently washed this bike, I have never ridden it in the rain. This lack of rust makes me wonder, though, if this mild steel or some other alloy. It looks like plain steel where it was ground. The outside of the bracket is dull grey in color, not like any stainless I am familiar with. I have queried Jardine via their web site regarding replacing the entire bracket. If they don't reply, I suppose I will give it a try with one rod or the other.
This size job is ideal for my little flux wire welder, but I don't have any 7018 wire. I might try to buy some...

Amtec264 will weld anything ........but back in the early 90's when we bought some for our shop it was $265 for ten pounds!!
:P
Sorry, just ignore me. 8-)

P.S. Our maintenance manager came to us and said "You boys won't be ordering any more of this rod ........understand?" LOL
Can you get to it with a small die grinder to see if it makes sparks, or get to it with a magnet? I may be visualizing it totally wrong ,but what about using silversolder? Just a couple thoughts..
Both good questions. I need to post some pics. The magnet is an especially good idea.
Watch this space for more developments...
Jardine has not responded to e-mail "chat" from their web site, or to messages left with whomever sales referred me to, soooooo, today I bit the bullet and repaired the bracket. The alloy must have some nickel in it, since it is scratched several places and shows no sign of rust. Nonetheless, 7018 rod welds it just fine.
The key to unraveling my reluctance to act was Charles' questions. The metal is magnetic, almost as strong a pull as mild steel. It is not finished, but the oxidation is grey, not "rust" colored.
It had been welded and ground off on the outside, but I decided to weld it on both sides. My only reservation is that the weld itself may show some corrosion. I will keep it well lubricated, and we shall see.
Net result, the play in the shift lever at the toe piece has been reduced from about 1 inch to about 1/8 inch. Works much, much, better.

nice job, i wish i was multi talented. Im just learning to paint,. maybe i need to learn to sand first :lol:
Jim, I do a lot of things. Designing radio frequency systems and the integrated circuits to implement them is one of them, and I do that well.
Other stuff, like painting, welding, fencing, etc., I do a mediocre job in most cases. I do love to try things, and I love the tools to try 'em with. Owning the Magnas gives me opportunity to try a lot of things.
I love your paint job. You are way past me in that department already.
Today I rode the red bike about 70 miles. I was not liking the forward controls until this morning. Having never experienced any, I just assumed the play in the shift lever was normal. It wasn't until I began to try to adjust the lever up for my new "tall toe" boots, per Terry's suggestion, that I figured out it was broken.
I really need a lot of help and advice, and this bunch of guys provide it in spades. What a blessing!
