Fork tubes jammed in sliders

make sure your side bolts in the lower tree are loose, slacken top nuts about half way, use a rubber mallet or put a piece of wood over the top nut and beat it down. They pop out.
 
Slacken the bottom bolt hidden under the front axle and remove the dampers and springs as a unit, then slacken the large seal-retaining collars at the top of the alloy fork slider - this is easier if you apply a bit of heat to the slider near the collar and then use a strap wrench or else put the collar in a vice and use the axle to turn the slider itself. Then compress the fork legs and pull them apart sharply like a slide hammer, you are effectively using the bottom fork bush to drive out both the fork seal and the top bush, so it takes a bit of enthusiasm and a quite few tries to get it all moving.
 
Do you have the tubes and sliders off the tree and the spring out? If so, the bushing in the top of the slider is almost a press fit inside the top of the slider. Take a strap wrench and take the top nut off the slider and then just pull up on the stanchion (tube) and you can knock the top slider bush out with the bottom steel bushing that is inside on the tube. Unless your tube is bound in the slider, then you will have to start pulling with something more. I see J. Bould has some slider inserts I think, I haven't looked into them much.

Thanks for the input, gentlemen. Here's my problem. The slider seems to be binding on the bushing inside. The further I pull it out the more difficult it is to turn until finally I can't turn it at all without putting some serious English into it. It's in there so tightly that it seems only some kind of inverse hydraulic press could separate it from the fork tube.
 
Remove the damper and spring and fill the fork with diesel or gas to thoroughly clean the insides out then spray WD 40, liquid Wrench or other easing fluid inside the fork and work it in and out until it gets easier to move, then mount it back in the triple clamps or well protected in a sturdy vise and use a rubber mallet to hit the top of the fork sliders downward. Just to get it started If you leave the seal retaining collar in place but loosened by a couple of turns you might try a plastic, leather or even copper mallet if you are careful not to damage the fork tubes, maybe wrap some masking tape around the tubes before administering the beating.

As an addendum, during disassembly heat up the lower legs with a propane torch but be careful of the potential fire-hazard of all of the volatile fluids that you have just used for cleaning and lubrication!!!!
 
Sometimes there's a bit of distortion around the oil holes above the steel bush in the fork tube which can bind in the top bush once all the oils out.

Try applying heat to the slider with a hot air gun. Once its good and hot bottom out the slider and use it like slide hammer, pull real hard and you should find the seal, top bush and slider all come out in one go (seal retainer removed of course).
If you've got a solidly mounted vice you can hold the slider with the axle in the vice, saves holding really hot bits.
