Default RE: How to: Rebuild your forks (F4 or F4i)

Hey guys, I'm trying to rebuild my f2 fork and I don't know where I went wrong. What I did was as this:

1st - Removed the 24mm bolt to drain tubes
2nd - Unbolted dampening screw at the bottom
3rd - removed clip
4th - Tried pulling the fork tube apart from the fork slider

Now here's where I'm stuck... I can't seem to get the fork tube apart from the fork slider... Why is that when I unbolted and removed everything inside the tubes itself... there's nothing in the tubes except ... nothing. I can't get access to the oil seals very easily so that's why I wanna pull apart the fork tube and slider but what the **** am I doing wrong...

Jahnaboi, If I'm interpreting your problem correctly you just need to give the fork tube and the leg a few solid jerks and it should pop right out. I'm thinking the seal should come with it because there's the race bearing type thing on the tube underneath the seal. It's been awhile since I did my f2 fork seals but I think that should do it.

I've been yanking on it for about 4 hours now.... it hasn't even moved let alone done anything but tire me out... I could bench over 200+ lbs and I'm pretty sure that should be enough to force it out... but still nothing... omfg... I'm getting pwned by this stupid stupid step....

Yes, the stock weight oil is 10 wt. Someone should put that in the How-To part of this post were it can been seen easy. Also the old oil seal, a block of wood and dead blow make a good seal driver that will cost you nothing and you don't need to search for. Push the new seal in s much as you can with you hand and then slide the oil seal down to it and use the block of wood and the hammer to seat the seal.

perfect. This is basically exactly the same for F2 and F3 forks. The only difference is socket sizes. First one took me an hour (gathering tools as i needed them), the second one took me 1/2 hour.

Thanks.

I totally missed the step on the seal driver tool and making one. Can someone point it out to me. I think I just may try to redo my forks on my own.

Which brings this question:
I had my forks redone. I have no idea what the oil type/level or weight is. The guy who did my forks sold his business and the new owner hasn't gotten back to me in ..... well, a long time. What do I do?
