Pressureangle Posted June 6 Posted June 6 JGP, does your clutch slave piston sit proud of or below the top of the cylinder? The parts link posted above *appears* to have the same slave as I ordered from Oberon, but doesn't fit my 2000- I wonder if it fits single-plate clutch bikes? 1
JGP Posted June 6 Posted June 6 (edited) The slave is a bone-simple device with 2 component parts. What I would call the block and the plunger. Within the block is at least 1 very thin seal could be 2. If you put a little compressed air to the hydraulic line inlet the plunger will pop right out. Not too much air, it does not take a lot. If I press on my slave which is part number 01 08 63 30, and built by Grimeca it will slide down into the bore of the block about 3/16" or more. It will extend from the block about a 3/4" or so before it will come free from the block. Not sure if that answers your question. I think the V11 slave cylinders were all the same and not specific to single or multi-plate clutches, but others likely know more than I do on that topic. Edited June 6 by JGP 2

Sounds like yours is as my original one- wondering why the drawing represents the later one. Meh.
JGP Posted June 6 Posted June 6 I suppose if someone put enough time and energy into it, those o-rings must be available somewhere. Lots of o-rings in the world....My old slave looks fine and I think it still functions properly, but it is starting to "sweat" a little when activated so, it's heading in a southernly direction. It could easily be rebuilt if the o-rings could be matched. 1

JGP Posted June 7 Posted June 7 No, it's not the bleeder. If the slave is off the bike and you activate the clutch, it sweats or weeps a little around the plunger. Very slight, but clearly the o ring(s) are starting to go. There is a little corrosion on the clutch control cylinder and the face of the slave plunger, but very slight, more like discoloration than corrosion. You have to consider, all of these o rings are now pushing 25 years old. 3
