another froze swinger bolt thread!!! OH NOES!!!!

[JasonB]

hahahah it seems to be a comon theme with me. My 83R had a frozen bolt that I think we put quite a few tons from the press on and tweaked the frame a little before it budged. Now my 86R that Im doing a frame up restore on is laughing at me from the gayrage with a froze up swing arm bolt. I hit it with 120 psi last night and it spins freely but has no side to side play. I pounded on it but need to get my sledge out. Thoughts on how to free it up? dont have a press at my house either :*(

build thread coming soon by the way. ordering parts NOW

Brake fluid, works wonders but let it soak for a day or so.

Large sledge , will help !

Keep us posted

Kroil works well.

I just did my swingarm bolt on my 200x. Had to strip it down to the frame and take it to a shop with a press. they cut the "head" off the bolt to press it out without bending the frame. I tried hitting and soaking it and everything I could before I took down to the frame and had it pressed out. It wasn't too bad taking it all apart. The problem was all the crappy bolts and threads I had to deal with. I spent a small fortune in new bolts and nuts because some idiot got their hands on the machine before me and thought they knew how to play mechanic.

I had to cut mine out with a sawzall on my 200x

Jason - we always end up cutting them out with a sawz-all. it is the easiest - but is still tough to get into the bolt without messing up the frame and or swinger.

[ATCrider42]

ya I was looking at mine wondering how the F**k people cut theirs out. I can see how easy it would be to cut into the swingarm or frame. Not to mention your gonna mess up the rubber caps there too. I ended up reusing one of mine and it saved me $10.00 and another week waiting for parts.
P.S. rdlsz24........nice 200x. That thing is mint. All original too isn't it? Is your swingarm polt in backwards though? it looks like the head of the bolt is on the chain side.

[JasonB]

lol sawzall NOOOO!!!!!! dont want to take that route. Atc-Enrique has 2 to use, but I just dont want to drive the bike an hour to press a bolt out. I SOAKED it in penetrating oil last night before bed. I will use a heavy dose of brake fluid too and see what I get. Also going to take a few swings with my sledge when i find the damned thing lol

[Mosh]

I tip the trike on the side with the nut off, and hose that thing down with the best penetrant you have for a day or so.
Spin the bolt with the impact from time to time and re apply penetrant so it runs down the bolt shaft..

Then grab the air and a punch bit and lay on that thing..I have a 20 inch long punch bit also that will go throw the whole swinger. Once you get them moving some go back and forth with it while using penetrant..
They come out everytime for me..even the ones I thought had to be cut..

[JasonB]

my air is broked!!!!! CRAP!!!! may just go invest. who knows, going to pour everything i can think of on it tonight.

A 50-50 mix of ATF and Acetone mix is an excelent penitration fluid. Here's a link but I think the test was actually done by popular mechanics or someone like that. http://grassrootsmotorsports.com/tech-tips/55/
So you deal with a lot of rusty nuts? Go down to the hardware store and buy some acetone, a quart of Dexron Mercon and a refillable spray bottle. In the spray bottle mix the ATF and acetone in a 1:1 mixture.

Spray away and get your nuts loose!

Independent testing of penetrating oils using a single steel bar with 1/2”x20 nuts torqued to 50 ft/lbs and treated with a 10% salt water solution that was allowed to rust. Listed are the chemicals and required removal torque.

-None ………………… 516 pounds

-WD-40 ……………… 238 pounds

-PB Blaster …………. 214 pounds

-Liquid Wrench ….. 127 pounds

-Kano Kroil ………… 106 pounds

Very cool,,will have to try that! That's a new one on me!

I cut mine out of my 200x without hurting anything

[Yamaha_Rules69]

I used a BIG sledge on mine after soaking it for weeks in all the different penetrating oils listed. This was on my 84 R. In the end, I layed the frame on its side, and used a BEEFY solid rod as a punch - about the same diameter as the bolt. You will need an assistant to hold the rod with a vise grip or two clamped together, to make sure you dont acidently demolish their hand. Give it a accurate, but powerful smack, and it will eventually come out. The thicker rod is better than a skinny punch, because it will allow for a lot harder hit. After you get the bolt flush with the frame, drive it home with a thicker punch. Also, the mixture listed above about the 50/50 mix is truely a great mix. You can actually see it going to work on the rust as soon as it hits it. The mix is actually supposed to be a mix of 50% acetone, and the other 50% is Power steering fluid. The author of the article spoke out somewhere, and said he was mistaken, and it is supposed to be power steering fluid instead of trans fluid. GOOD LUCK!

What I do is thread the nut back to where it sits flush with the end of the swinger bolt after being drenched with wd40. Then I find a strong bolt that fits in the ID of the swinger bolt. Get my short handle sledge give it a couple of good wacks....and they come out everytime.
