  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Screwed up! Used brake fluid in Magura clutch...oops!

I'm pretty ignorant about hydraulic clutches...first one for me. (used to japanese bikes)

Anyway...out riding and my clutch gives out. Get it back to the truck and pop the reservoir cap and the fluid is below the hole. I look on my phone for what I should put in there...but signal is sketchy and I find a synopsis of a 2005 TE. Anyway it said use dot 4 brake fluid. (I guess the synop was a from a different model since this is wrong)

After asking around...nobody had any. Had to drive 25 mins and got some from Autozone. I get back and just top off the fluid...pump it up and ride for an hour then forgot about it. This was last week Saturday. Reading my service manual today it says "Do Not use brake fluid" GAH!

I'm guessing I added an ounce? Anyway...I had mineral oil so I did a reverse bleed full purge twice. Got everything out I could. Fired up the bike on the stand and the clutch is fine. Zip tied the lever and that's where I'm at now. I will purge again and use Magura blood (or equivalent) later.

What seals might I have borked? I know brake fluid is corrosive but I'm hoping the ratio was small enough...and it wasn't in there very long...that I might be ok.

Thoughts?
 
I don't think that there will be much of any consequences from that. I once refilled a Gas Gas clutch system with mineral oil instead of the recommended dot 4 and never had one problem with it in five years. However, I am more concerned about the fact that you lost fluid in the first place. Probably time to rebuild the slave unit, using a 7602 piston and x ring. This is what I did for my 2007 TE 450 when it had a problem, and it remained good after that.

Good point! I pulled off the slave unit last night...first thing I noticed is there was no gasket. There was a bunch of fluid inside...I guess my seal was porked and leaking inside. I bit the bullet and bought a complete Oberon replacement and have Magura blood on the way. The bummer is I don't think it will make it here for the weekend ride!

Thanks for the help :cheers:
