Fork rebuild tools
« on: December 30, 2014, 06:00:57 pm »
I will be changing fork seals on 99 yz250 soon, i think they are kyb, comp on bottom rebound on top, ive done showas with alan on honda before but want to learn to do these on my own. What special tools am i going to need besides seals and bushings? Damper holder? Seal driver size? Any tips on this?

Pretty much what you need for Showa, cap wrench, seal driver, etc.:

I've only done Showa's, so can't offer specifics.

Adam, I have the tools. I have 3 different seal drivers, yours should be 48mm. I have the fork cap wrenches, fork cartridge holder, oil leveler, seal bullets and some other stuff. I have tons of kyb valve shims if you want to mess around with some valve stacking. Also have shock tools.

I just ordered WP suspension tools. I will be tearing down my suspension in the next couple weeks.

Id like to valve it for woods, but i don't know what to do for that. The forks are terrible in the small chattery stuff like my showa were once i put the 450r springs in

You shouldnt need any special wrenches for them, im pretty sure the caps are just 17 or 19mm hex.  If you want to take the cartridge out you might need a special wrench. seal driver for sure though.  Your bike has 46mm for legs.  48mm wasnt until 2004.  Get the right weight springs for your weight while you have them apart.

As for re-valving, this was just up on thumper talk.  The 2000 should have a very similar for to yours.  some good info there.  If you are going to soften the fork up, I would recommend doing the shock too.  The bike will feel wonky if the for is plush and the shock is still harsh.  The shock could probably use new oil and a re-charge anyway.

And definitely the seal protectors that cover the tube when you slide the seal over. It's a lot better than a plastic bag

Pretty sure I have the 46/47 mm drivers in my box. You have a vice in your garage with soft jaws? Not that you need it butmakes the job a lot easier. We can get together soon and have a couple beers and do the revalving. I will bring all the tools and you can have the fun. I will bring my grinder for the rear shock valve, most likely it hasn't been tampered with yet. All my WP suspension stuff is on the way, can't wait to tear it down.
