GT Stem Adjustment

Hello everyone!  This may be a dumb question to some of you but I'm a little rusted on the assembly department.  I was trying to take a part the stem on my GT but is not coming of.  I loosen the stem bolt and try to yank on the stem but it did not budge.  I really don't want to hammer on the stem since is in good condition.  My question is, am I forgetting a step or something?  I never took apart a bike with a rotor so I'm not sure if I'm doing it right.  Any advice would be appreciated. 

Here's the pics:

Or hit it with a rubber mallet. Less chance of damage incase the 2x4 splits.

Re: GT Stem Adjustment

Actually the bolt is off.  I can't get the stem to separate from the frame.  Feels like is stuck on something and won't even spin around. Do I need to loosen up the headset nut on top of the rotor for it to come off?

Re: GT Stem Adjustment

The wedge bolt is probably stuck. You need a penetrating lube on it for a bit. I use transmission fluid myself. Works great. If that doesn't work then idk.

Re: GT Stem Adjustment

Put the front rim in between your legs and twist it, it should free it up

Re: GT Stem Adjustment

Flip the bike over and drop some transmission fluid down there and let it sit over night and then flip it back over and make sure to wipe down the excess incase it leaks out. Put the other bolt back in until it's about 1/4 inch from being all the way in and then hit with a rubber mallet. That should do the trick. If not I'm stumped. But either way you shouldn't have to remove the top nut.

Re: GT Stem Adjustment

So the wedge is still in there? The above advice is all very good.

These are sometimes mildly/moderately frozen on. Face the back of the bike, put the wheel between your legs and give a firm, quick twist on the bars. When I take stems and bars off, that's the first thing I do (after loosening the stem bolt of course).

You could lubricate as suggested. Maybe even reconnect the stem bolt before or after to realign everything, lubricating, and the twisting method.

Once this comes out, use some grease to make sure the surfaces are less prone to stick together.

Re: GT Stem Adjustment

Thanks!  I will definitely work on it this weekend.  Hope it comes out.  I never had an issue like this before.  Oh well, it's a learning experience.

Re: GT Stem Adjustment

When you reassemble, coat inside of fork steerer with grease.

Re: GT Stem Adjustment

NO HAMMER!!!!  As a golden rule, during a breakdown or re-assembly, anytime the hammer comes out usually equals broken or damaged parts.  This has happened to me a number of times.  It's just corrosion inside the steer tube.  It will come out.  Put the bars back on and the tire and work it that way.  It will come out.

I fear using the hammer also.  I have difficulty controlling my strength, LOL.  I haven't got to work on it, my good friend's passed away friday and I haven't had a chance to work on it plus I had to work on my in-law's car the past two days.  Hoping tomorrow I get a chance to work on it.
