Seizing....what to do?(5 posts)

Seizing....what to do?Krypton
Mar 27, 2002 9:32 AM
I have an 11 years old Moutain bike that I would like to convert to a winter bike. There's an old Manitou suspension fork on it that I would like to remove to install a cheap steel fork. The problem is taht my Synchros aluminium stem as seized in the steirer tube. I tried to free it by using a rubber hammer to no avail.

Anybody here knows how to get it out, any help would be appreciated.

Haven't tried any of these except brute force, but I remember them from previous posts on the subject:
You HAVE made sure the wedge is loose, right? Unscrew the bolt several turns, then rap it smartly with a hammer to make sure the wedge at the bottom isn't jammed.
Ammonia is supposed to dissolve the corrosion (penetrating oil won't). Flow some in there and let it sit awhile.
Clamp the stem in a vise and use the front wheel as a lever to turn the fork to see if you can break it loose.
As a last resort, since you're going to replace the fork anyway and quill stems are dirt cheap, just cut it up with a hacksaw.

Thanks....

Yep the wedge is loose. Ammonia, good, I'll try that first. I was almost ready to saw it, but I wanted to try a non destructive method first....but if it comes to that, well, that's what I'm going to do!

Thanks again for the help.

I had good luck with Liquid Wrench followed by a hard rubber hammer.

Applying heat froma torch can really free things up. Of course you're going to smoke the grease in the headset and may even damage the paint on the headtube. Since you don't really care about the fork or the stem cutting it would be the easiest and safest.
