nicked my USD forks.

Post by newbbewb »

just had the left leg(caliper side) 93 USD forks start leaking a bit. After getting into it, noticed there is a bit of a nick. I cleaned her up best i could with sandpaper to take the sharp parts out. What do you guys recommend trying before i start on it?

I would like to save these if possible, i just had racetech springs and full service performed. I then proceeded to fall into a rock pit :-)

I've never done this, but I've heard of people filling the nick with super glue and then sanding it with very fine wet sandpaper - like 2000-4000 grit.

I've used a wet-stone to polish mine out successfully - if the nick isn't too deep.

If the nick is too deep to just remove the bur and smooth out then you could use silver solder to fill in the bad spot and then smooth it back out. This has been used for years as a quick fix for hydraulic cylinder rods with success.

Thanks all for the input. I know I can send em out, but spending that kind of time and money, again, on these forks.... Not going to happen. I'd get kx forks.

Super glue is an interesting idea. There is a void in the metal that needs to be filled in order to stop/slow the leak until this winter.

Silver solder I have no experience with and sounds like it could be more stable fix. Is there a good brand/style I would want to use? I take it flux core solder and my weller iron aren't going to do it. After research, it looks like it's basically brazing?? So use a MAPP gas torch?

Silver solder is more of a "brazing" method but with solder. Give a try on something you don't care about that much and you can get the hang of it. And as far as brand you could go to a welding supply shop and ask them what they would recommend.
