Hey guys

Today I tried to adjust my chain but came across a problem.

The chain adjustment bolt on the left hand side has completely seized.
I have tried everything I can think of.

Apply copper antiseize
Wiggle the bolt to break it free
Apply more antiseize
Loosen & tighten the bolt
Curse at it while going to town on it with antiseize.

At the minute nothing seems to be working.
Looking online this seems to be a common thing with bikes.

Have any of you guys come across this issue? how did you get around it?

Thanks

Edit:
The right hand side is nice and free, I have also attached a couple of photos.

 

If you mean it is stuck and will not turn, I'd try heating the swing arm at the bolt. Aluminum will expand at a higher rate than steel. The threads should open up a bit.

When hot stick a small candle on the bolt, the paraffin wax will flow in the threads. Read that either here or in a hot rod magazine.

 

PB Blaster is much better to loosen seized bolts.
Apply and let it soak in. Then use heat if it doesn't still doesn't come loose.

Anti seize is what you use on the threads to prevent the threads from seizing.

 

PB Blaster all the way. Spray every 2 hours or so for half a day, then let it penetrate overnight.

 

Having snapped one off and fixed it by drilling it out...trust me when I say be patient and don't apply too much force if it ain't moving. The bolt head looks like it's seen some force already. Too much force can bend the bolt, which happens to be about 4" long, and make it hard to run it through the deep threads in the swingarm.
A good rap with a hammer and punch after soaking in PB might also help, but hit it square on the end.
And spin the fixing nut up out of the way so you can get some PB in there.
Might want to go at the bolt threads with a brass brush once it moves.
Good luck.

 

Thanks everyone for your replies.

I had another look at it today after reading this thread.
I ended up taking the wheel off to give me better access to the bolt.

Using a socket set, I could move the bolt a little better without applying too much pressure.
The bolt is now in the position I want it to be for the time being.

In the mean time I can take a look at getting some of this pb blaster ready for my next chain adjustment.

 

It's never to early to start spraying it with PB Blaster. The more time it has to get in there, the better it will work and the easier it will be to loosen when you need to. I'd start spraying it at least a few times a week or after each ride if you ride often. Just a quick squirt.
