Title: Is this what the great open clutch Ducati sounds like? Or I have problem?
Post by: JimmyTheDriver on December 09, 2012, 12:24:02 PM
My clutch has some squeak when pulled.  Sounds like it comes from the slave, but its hard to tell.  Lever pull is a bit rough.

I bled, greased a bit, and there is still squeak.  I figured it was in the slave cylinder, so I have an Oberon on order.  Today, on a whim, I took off the clutch cover.  Are these sounds normal?  The squeak when turned off is something I already knew about, but is the insane squeal when turned on and clutch engaged normal?  You can't hear it when the cover is on, so I had no idea it was squealing this bad when engaged.

I've owned the bike for 3 years, and have never heard mine, or any other Ducati with an open cover in person.

I can't see the video - do you need to make it public?

Amateur hour over here... they are public now.  Thanks!

Haha it was moved to tech, is that a hint I have a problem?  ;)

I know nothing about this problem (wet clutch here), but it must belong in Tech....

[popcorn] money says it's an easy fix (once you know how)

I think the squeak is just dry springs, other than that it sounds great   [thumbsup]

The squeak isn't right.

Pull the pressure plate and check the rod.

I had the rod out when I took off and inspected the slave. Looked fine to me then.

I've never taken the clutch apart but it looks easy. Should I go in and check out the bearing I know exists somewhere in there?

The bearing is in the pressure plate with a seat for the rod.  It is pretty simple to take off and disassemble the clutch. Be careful with the screws on reassembly, more than snug and you stand the chance of stripping or breaking something.

A little grease on the end of the rod where it enters the push piece is a good idea too.

My springs squeak a bit. A bit. That's a lot.

One way to possibly locate the squeak is by using a thin screwdriver as a stethoscope, handle to your ear, tip on suspect part (engine not running please!).  If you think it is a part that would get wet anyway, hit the rubbing parts with water.  If the noise is eliminated or diminished you found it.

Sounds like the springs to me either corroded or not seated properly. It wouldn't hurt to grease up "your rod." [Dolph] The bearing you want to look at is in the center of the pressure plate you can see it from the outside probably not the issue though. If it is sealed, doesn't appear to be damaged and rolls smooth then its good. Don't be rough when removing the clutch springs or putting them back on many have broken the clutch post using the great man force. Remove caps like you would a wheel in a star pattern ease the pressure off. If they won't come off with ease add heat. Some pressure plates have little marks on them to help guide placing the plate back in the correct position. All you need to know that the notches on the pressure plate need to line up with the clutch hub upon reassembly if they don't and you start the bike you'll be breaking shizzzz.

Whoa Jimmy that is nasty!  The one with the engine not running is just not right.

That can't be the bearing because the bearing is completely idle without the engine running.  Corrosion or a buildup of clutch dust crud on the spring bolts is my guess.

Remove the pressure plate, throw it away, install new blingy pressure plate, New SS springs, New Ti hardware and an open cover of you choice.  Problem solved for <$500.

Or you can disassemble it, clean it and put it back together.  But what fun is that?

Haha new plate sounds nice.  I've been meaning to open it up anyway.  I removed the existing springs , cleaned off a little, and put back on with decent results.  Bearing seems fine.  I'll likely just replace the obvious with some bling and call it a day.

The stock springs do look pretty rusted up.

Thanks!

I hate it when stock parts go bad and I have to order the open clutch combo I've wanted for years...
