removing the clutch slave?

[gstallons]

Do you have the clutch alignment tool ? Also , when you go back together , clean ALL splines and spray a dry film graphite spray on all splines to keep rust away and for easy movement.

You show me a picture like that on a mid-May afternoon? I am going back to pruning my blueberries.

Not a bad call. The clutch is a deep dive.

I was thinking it might be worth strapping the clutch lever to the grip and administering some judicious purcussive intervention to the slave cylinder (beat on it). Nothing lost by leaving it strapped overnight and tapping on the slave again . . .

Last summer a guy up here had clutch trouble with his V11. It was the slave cyl. Visible grazes on the piston. Flat on the back side, doesn't need much room to remove.   Not many around, found 2 in Denmark last year.  Rivets let go on my Rosso Corsa clutch   = no clutch.  Changing the clutch is like having desert compared to interweb and likes.

Cheers Tom.

Oberon, who made my gas tank filler cap, also makes v11 clutch slave cylinders. I'll need one myself shortly. They have their own eBay store.

 

It seems their website only shows back to 2005- can anyone confirm fitment for prior years? I don't know why MG would have changed it later.

The site only says Moto Guzzi . How did you get the application ?

This does look to be correct. I know it lists Moto Guzzi but you would have to get it and see . Maybe Oberon could verify it fitting all V11s from 2000 til the end of production. I don't see how ot could be different.

Problem is it's not just a matter of will it bolt onto the gearbox but also a matter of are the dimensions and piston travel exactly the same. The Oberon unit looks like it's for a Norge and Breva etc. I know when I updated to the single plate clutch I did some measuring and the length of the pushrod and the travel of the piston is highly critical. Whether the later model bikes use the same mechanical dimensions I don't know. I still suspect the low KLMs you get out of the original sintered friction plate for the RAM single plater when used on a V11 could be simply down to the clutch slave bottoming out as the clutch plate gets about 1/3rd worn because the RAM single plater was originally designed for the 5 speed with the cable operated clutch.

I also can't imagine why it would have been changed.

I went looking. Searching one of the part numbers quoted by Oberon, GU05086330, I got this at Stein-Dinse

https://www.stein-dinse.com/de/moto-guzzi-kupplungszylinder-850-1100-1200-breva-griso/item-2-1030607-GU05086330-.html

 

Looking at these parts lists, choose "clutch" from the index, part #13 on the apparently same drawing in all of them, I got the part number GU01086330 on all of them.

So my opinion:

Firstly, it seems that the V11 models did indeed all have the same clutch cylinder.

Secondly, the clutch cylinder pictured from Stein-Dinse is listed as being for the "next generation", i.e. Breva, Norge etc., but looks remarkably similar to the clutch cylinder on my V11.

So, even though the Oberon part is apparently not specifically listed for the V11 models, I reckon I'd be willing to take a punt on it. If only because it comes in such pretty colours.

I can't see there being any difference between the single plate and dual plate system on the hydraulics.

V2 Parts in Denmark. Not sure what tariffs do to the price. I picked one up last December. I have not yet pulled the old one to compare, visually, exterior looks the same.  Seems like others here have had success with it.

No but there's a bit between the hydraulics and the pressure plate such as the pushrod length, and the pressure plate receiver for the pushrod. Also the clutch pack thickness has a relationship to the clutch slave cylinder travel in both directions. Imagine if the Oberon slave cylinder had less travel to the piston in the released or clutch engaged position. You could end up in a situation where when the clutch plate wears down and the piston is pushed further back into it's bore it bottoms out and then prevents the clutch from fully engaging..

I'd love someone to buy the Oberon unit and fit it so we know if it works for sure.

That is the only place(s) it could be different. a person would have to take time and check all part #s between a single plate/dual plate system to find out what is different. 

[JGP]

There are only 3 differences noted in the parts book between the single plate clutch and the multi-plate. None of those parts relate to the slave or the push-rod assembly.
