• 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 The previous version was outdated and no longer supported.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!

O-ring replacement for Magura Clutch

I have searched this forum as well as a couple of others. Does anyone have a good write up for doing this? I know this is a pretty easy task but it scares me to tear into this without having more info. I recently got the X ring from Uptite and want to get this done before I have a problem.

TIA
 
Pretty straight forward. remove the slave cylinder from the bike.

DO NOT PULL IN THE CLUTCH WHEN THE SLAVE IS OFF THE BIKE!!! IT WILL BREAK THE SLAVE CYLINDER AND YOU WILL BE INSTANTLY PISSED!

With the slave off, take out the retaining ring. carefully pry the piston out. I use my fingernails under the center post that has the ball in it. Set the slave down with the open pocket facing up so all your oil doesnt run out. With the piston out, remove the old ring, install the new making sure it is not twisted. lube the ring up with some mineral oil. I use singer sewing machine oil for the clutch, its like 2 dollars at walmart and is a little lighter than the magura blood.

Now fill the pocket in the slave with mineral oil and reinstall the piston. Push the piston down to reinstall the retaining ring. Put the slave back on the bike and bleed.
 
Do I need to ake the hyd line off the slave? Sorry for the dumb questions. Maybe I can find a picture of the insides somewhere so I can better visualize what you are describing.

Thanks Colomoto....I will see if there is a picture anywhere to help with the O ring installation.
 
You don't need to take the hyd line off the slave to change the oring. Once you get the slave off the bike it will be pretty clear what you need to do. There are only a few parts and it really is very straight forward.
 
Concerning the mineral oil ..... so the thinner "Singer" oil is a good substitute?
How about simple hydraulic oil ...like what goes in your floor jack?
I've got that in the garage now. Is it too thick? Surely it's been tried.

Thanks, dave
 
Never heard of floor jack oil being used. I did some research into the singer oil a while back. It's basically highly refined mineral oil. Couple other guys had tried it and nothing blew up, so i thought I would give it a go. It seems a little thinner/waterier than the magura stuff, and was only 2-3 dollars a bottle. Ran it since late July with no problems.
 
Any idea on a part number or alternate places to get the x ring in Australia? Ordering a single ring from OS is gonna be a pain.

Any thoughts on whether they will last as long as oring or not?

Any good auto or ag parts store should have a good selection of o and x rings. If not try online stores. Be very picky on the fit though.
 
I finally got around to replacing it, local bike shops couldnt source one, nor most parts or bearings places. Ended up at a place that repairs air tools (nail guns etc) he found me one is 3 sec and gave it to me for free. (i left some cash anyway). Installed, gravity bled and all sorted in a few minutes.

BTW the air tool repairer was Bernie Adams, says he was heavily involved in Husky MX back in the day...anyone heard of him?
