Guest Jeff in Ohio Posted June 14, 2006 Share Posted June 14, 2006 This is for 5 speeds (Cali's, Centauros, older spots etc.) Need help with the German translation: http://www.moto-spezial.de/F6055.html Says it uses radiator fluid? Any of you European guys ever seen one of these? Looks pretty trick... Link to comment Share on other sites More sharing options...

The reason for using antifreeze is that the rubber in one of the cylinders is not oil proof, the other is not brake fluid proof. You could use any liquid but antifreeze has a reasonably high boiling point. I assume the kits at the bottom are the slave cyliinders with hydraulic hose. Can't see any other reason for a difference between clipons and touring bars. Take your pick of masters from the list above. Seems like a reasonable price. Nice idea for clutch free play adjustment. mike Link to comment Share on other sites More sharing options...

I sent them an e-mail. Hoepfully they can speak english. If it uses standard o-rings and he ships to the USA, I'm buying one.... Link to comment Share on other sites More sharing options...

Designed so that, as the pressure increases, the seal gets better. O rings would leak like a fish's bladder under pressure, although they might be used as backup to prevent stuff getting on the bore. You still might be able to get hold of replacements for the cup seals. But it's not a problem to use antifreeze, if the rest of the system is properly designed. (Note the above is CUP seals, not CUB......) mike Link to comment Share on other sites More sharing options...

(Note the above is CUP seals, not CUB......) mike 92039[/snapback] I figured it out. They sent me an instruction sheet. The assembly replaces the outer body with a housing. the OD of the housing as an o-ring that seals in the counterbore of the transcover left by removing the ounter body. Inside this housing is a piston with a quad ring that pushes on another piece that acts thru teh stock needle thrust bearing that pushes on the inner body. On one side of the quad ring is ethylene glycol from the clutch master cylinder. the other side of the piston is exposed to the inside of the trans and thus, trans fluid. EPDM seals while safe for brake fluid use are not compatible with any oils. Since the quad ring has trans oil on one side, teh EPDM seal wiould swell like a baloon and seize the assembly. Ethelyne glycol however is compatible with every seal knwon to man, including the EPDM ones in your hand master cylinder. I was unable to find any seal material you could use that is compatible with trans fluid AND brake fluid. About the only real 'oil' that could be used would be silicone oil (NOT the same as DOT 5 though!!) as the master cylinder seals and slave cylinder seals would both be compatible with it....

Any of you European guys ever seen one of these? Looks pretty trick... 92007[/snapback] Jeff, check out the translation, courtesy of Babelfish (www.altavista.com) ---------------- moto specially GmbH, Uracher STR. 23, 72532 Gomadingen, 14.06.06 Hydraulic clutch for Guzzis The hydraulic clutch manipulation consists of 2 hydraulic units. Master cylinder Nehmerzylinder (??) These are connected by a pressure pipe. The function of the clutch separation is realized hydraulically thereby. I.e. the master cylinder displaces liquid, which the nehmerzylinder (??) converts in mechanical motion during operation. Thus the clutch is separated. The stroke thereby amounts to approx. 2,5-3mm. The used liquid with the Guzzi solution is radiator liquid like one it from the motorcar radiator knows. (with conventional systems brake fluid) this has the following reason: The used rubber parts are brake fluid compatibly however not oil compatible in the giving cylinder. In contrast to it the rubber parts oil-compatibly used in the nehmerzylinder are however not brake fluid compatible. There in the transmission however oil is gives it a boundary surface between oil and the hydraulic system. The radiator liquid is however a liquid, which is compatible with both rubber places. This liquid is applicable also at temperatures to approx. 130°C. The advantages of the hydraulic clutch: accurately defined pressure point State of the art with the new Big bikes unproblematic assembly outstanding dosage thus clutch-carefully no wearing, or clever clutch courses more Hand strength continuously approx. 75Nm ------------------------------ Søren Link to comment Share on other sites More sharing options...
