Thanks JB.... I am not a master mechanic, but I am also not a complete idiot...so I am told. I read an article this morning on line that said you should fill the fork with water and put it under load. The pressure will pop the seal. Water is cleaner then fork oil and since you have to clean the fork before reassembly, the water should not harm the fork. Sounds like it could damage other components... interesting concept though.

How do they propose to "put it under load"? I suppose you could thread a hydraulic fitting into the drain hole, or maybe an air line. I've always just used lots of rags to protect the legs and lowers, and secure the sliders in a vise and let it rip. The fork tube won't distort before the rubber seal breaks loose. You just need to show it who's the boss.

you can also hold it with an old automotive belt and crank it down around the slider with a vice...the rubber gets way more grip than cloth and would break long before the slider would bend.

the article just suggests you push down on the fork and compress it. If you have it filled up to the top with water, it will create enough pressure. I am not going to do it. There has to be a better way.
Here is the link to the website/blog:

if you have access to a shop press (the big frame type) you can use that to force the seal out with water or oil; this is going to make a mess though. Watched this done to an upside down fork from a dirt bike that was particularly stuck, but watch out when it goes!

if at first you don't succeed, use a bigger hammer

No access to a shop press.

Are the tubes out of the legs yet?
When the tubes are out, and the clip is removed I usually just stick a screw driver in there and pry them out. Usually they are pretty flimsy and just bend up and pop out.

or if it's all still together, filler up with water, and do stoppies till she blows.
parks
p.s. get video of the procedure and put it on u-tube.

You could always remove the bottom plug and spray some quick start/ether into the hole and light a match. I am not sure how well it would work here but it works great for seating transport truck tires on rims

Hey someone pas me the wrench........ Ahh screw it where is the torch

JB - Tubes out...seals are pretty caked on...I should have changed them long ago. Real old and dried out (Kinda like Champ). The Seals for the CB500 also have a metal band in them (I thought that was weird). They are not so flimsy...unless I ordered the incorrect seal, which I am pretty sure I didn't. I'll figure it out or destroy it or me in the process.

I am a bit gases from my tex-mex supper lastnight, maybe methane gas will work...

also you can get a piece of 1" x 1/16 or 3/32 and fold it over the lip of the leg to pry against..so as not to dent the top edge , 1 good wack on the screwdriver is all I have ever had to do.
