Showa Twin Chamber Problem?

[dirtrider2002]

Hi,

I recently removed my forks on my cr250 to check oil levels, and when I removed the cap, I found alot of metallic shavings. So I disassembled my forks, and there was only fluid in the inner chamber.

I've attached a couple pictures, and hope you could maybe tell me what the problem is, as I have not worked on this type of forks before.

Also, if you could let me know how much oil to put in both the inner and outer chambers, and where to put it in.

Thanks

Here's the pics...

thanks

any ideas, I could use the oil amounts as soon as possible

For the 02 and 03's, std amounts:

Inner -

02: 185cc

03: 195cc

Outer -

02: 419cc

03: 405cc

It's hard to tell from the pics and without seeing the tubes in person, but did you check the bearings/bushings and the inner surface of the outer tubes? If it ran without fluid, you may have galled them since the fluid provides lubrication for them.

Sometimes the hard anodizing wears through on the outer tube. That can make the oil look black and wear away alot of aluminum. Check bushings for aluminum particles in the teflon. If so, replace them. Then inspect the inner part of the outer tubes. You may need to have the hard anodizing redone on the inner part of the outer tubes.

Thanks,

I checked the bushing surfaces and they look good, I'll check the inside of the outer tubes, and let you know.

03: 195cc

The final measurement for the damper (inner) chamber is an oil height between 1.65" and 1.85". I've always just used 1.75" .

Another thing, if you can identify what type of metal it is that you found it would narrow down where it came from and assist in knowing what's really wrong.

And where did you find the shavings exactly? If they were down around the bottom where the rebound damper clamps to the slider they may have been there a really long time.

I found quite a bit of crap in my fork after just 5 hours of use. But none since (60+ hours)
