i think the problem is a bit of both the new oring on the slave cylinder certainly improved the sealing around the slave cylinder but i think the plunger in the resevoir could have been on the way outas well, because after getting the new plunger piston there is no comparison with the old one it was stuffed . Now 2 points lotsa the o ring for the slave cylinder take your old one to a cbc bearing ( or in my case it was a SKF bearings at sandgate newcastle who i cannot say enough about they have helped me heaps)and they will size it up for you and give you a replacement one he ended up just giving me one for nothing. POINT2 now when you are going to replace your magura clutch plunger / piston remember there are quite a few brands that use Magura clutches, when i rang up watsons at cessnock a husky kit for the magura clutch resevoir was $130 for the same thing off a TM dealer around the corner $ 41 bit of a difference EH! it looks a little bit different but it fits and it works. and just on a quick note on SKF bearings when i done the bigend rebuild on the husky mains bearings from the husky dealer $145 each SKF had the same C3 bearing but without the groove for the retaining clips for $8. 50 i then took them to a toolmaker who put them on his lathe and machined the groove in them for mefor $40 so all up it was $57 and there is no difference just make sure you ask for C3 bearings as these have the right tolerences, ive done about 700KM since the rebuild all is sweet. so my advice is get a bit of a relationship between you and your local bearing and seals dealer it will save you heaps . cheers Ian

Thanks Ian
I did just that. The slave piston oring is 24 x 2mm and the clutch is working. A better test on the trails. There are some rub marks on the bore of the slave cylinder but I’ll see how it goes. If the TM dealer around the corner in Cessnock is also the KTM dealer in the main street I’ll get a reservoir plunger from them or a bloke in QLD.

Thanks for big end info. I hope I don’t have to use it though.

Happy trails[/quote] that would be the same place tm/ktm dealer in the main street and another thing if you google 7602 racing have a look at the replacement slave cylinder they have it is a bit thicker and uses a quad ring (oring) it is a husky sight but as i said magura clutches are used on other brands so it should fit .cheers

well ive found the problem i replaced everything used different oils pulled my hair out, cryed a littlebit in my sleep but it ended up being the slave cylinder housing as the actual slave cylinder is thin it kicks around a little bit and after a while scores the barrel i can see where it leaksair when i push the slave cylinder in and hold my thumb over the top where the hose/ bleed bolt joins it stays in but touch it and the slave cylinder pops out with out taking your thumb off the top and though they are only minor you can see the scoring in the housing barrel so im going to check out one of these replacement slave cylinders from 7602 racing tell how i went. so check that out lotsa if you cant fix your fading clutch. cheers

My slave cylinder bore had a rub mark just in one area of about 1mm by 3mm but not scored. That in itself is enough for replacement of the part though. After replacing the oring and pressure applied, there seemed to be no leakage from the engine side of the slave piston/bore with the piston forced against the circlip.

I’ll test it out with a short ride this Saturday.

Could you let me know if the 7602 slave does the job and I’ll replace mine.

Gave the clutch a good workout last Saturday on Murfs basin ride. Just checked the fluid and its at the same level so all good so far.
