Guest Posted July 3, 2012 Share Posted July 3, 2012 Is there an easy to follow walk through?Mine aren't just a small weep, the whole fork is covered and it is dripping on the floor.(Still gives me chance to put some heavier oil/right amount in to them) Quote Link to comment Share on other sites More sharing options...

Tango Posted July 3, 2012 Share Posted July 3, 2012 Fork seals aren't generally that hard to do. The hardest part normally is getting the old seals out....especially if they've been in there some time. As Stu says...a lot depends on the bike. I replaced them on a Triumph Trophy I had a few years back....and getting them apart was a right game with the bottom bushes catching on the seals...so I couldn't actually get the sliders out without a bit of brute force. Anyway even on USD forks the principles are the same. You may need to apply some heat to the fork tubes when trying to get the seals out.......but they should come. Just be careful with the oil viscosity and quantity......we did BonnieBirds daughters CG125 earlier in the year...and even a small amount too much oil (but still the right quantity according to the manual) locked the forks solid.... removed a few CC's and they worked fine.....

Guest Posted July 4, 2012 Share Posted July 4, 2012 It's a Hyosung.I know for a fact that the fork oil will be too low in them, they had that problem from the factory.Stripping the front end off isn't a problem either. Done it more than enough times during the rebuild to even think about it. It is just the fact of stripping a fork down.(Bear in mind never done it on usd's before)How are you meant to get the new seat over the stantion or bottom without breaking it?I mean surely they have to come apart but does the bottom come off or the top?Last fork seals I changed was a shitty old H100s II we scraped the old seals out with a knife and put the new ones in with a hoover pipe and sledge hammer (used lightly of course. )No idea what i'm doing hear. So will whack the leg off tomorrow.Which will make my dad extremely happy to have my bike hanging from the roof again with his underneath it. But hey ho, jobs got to be done. Might as well do both whilst i'm at it.Also need to sort out the wiring loom since it was a right pig to get the air box back on, so that might have to come out again. Rest of the bits should be here on fri for my bike, so it will be road worthy and then it is just the license to deal with. Quote Link to comment Share on other sites More sharing options...
Fozzie Posted July 4, 2012 Share Posted July 4, 2012 Search on youtube for a guy called WedginatorLook at his guide to swapping fork seals on a Ninja which are USD. Its very comprehensive! Quote Link to comment Share on other sites More sharing options...
Stu Posted July 4, 2012 Share Posted July 4, 2012 You need to split the forks to replace the seals and remove the bushes to slide the seals off, You may aswell replace the bushes while you are at it, Look at that guide that I posted above I bet yours aren't far off that the only thing you done need to do is remove the valves like in the guide Quote Link to comment Share on other sites More sharing options...
Tango Posted July 4, 2012 Share Posted July 4, 2012 Hang the bike upside down....then change the seals as you would normally...... Quote Link to comment Share on other sites More sharing options...
Guest Posted July 5, 2012 Share Posted July 5, 2012 Hang the bike upside down....then change the seals as you would normally...... Funny you should meantion that.Stripped the forks off tonight (30mins) and took them to the bike shop .Couldn't find the space in my garage to leave my bike without a front end or, a trolly jack to monover it. So I just used my skills, and hoisted the front end up in the air with a chain block, to remove the front end, the lowered it back down on to the floor and picked the rest of the bike up.http://i682.photobucket.com/albums/vv190/Rocketgt650r/100802_174120.jpgMy nephew who was meant to be helping me, run off with the camera before I could upload the rest of the pictures (little bugger). I'll try get some tomorrow when I find it again.P.S. I am a rigger so know how to find the center of a load. Hence how level the bike is.
