Title: Ducati clutch push rod - spin or not? Post by: Mr.S2R on October 07, 2010, 10:51:56 PM Hey Peoples,
Just replaced my clutch pack, and pressure plate bearing. I noticed when the bike is running the rod (or rod hat) spins a little inside the thrust bearinga little. I have looked through other forums and searched here but there does not seem to be a definitive answer. Should the rod spin? If not how do I fix it? Just to be clearer on what I define the degree of spin or rotation. At idle the push rod does not spin, and does not until about 7000 rpm, then it is a very slow rotation. Normal? cheers [thumbsup] Title: Re: Ducati clutch push rod - spin or not? Post by: loony888 on October 08, 2010, 12:01:53 AM yep, completely normal.
when the bearing fails and the pushrod spins at the same speed as the pressure plate it causes major problems with the slave cylinder, always a good idea to change the pressure plate bearing to avoid that problem. bet you never even looked at how the pushrod and hat sat and moved before? paul.

[thumbsup] I change my bearing every service without even looking at it! Have found one a bit notchy so I changed the shaft seals as a matter of course. The bearing is only $6 or $7 and the seals $3 or so. ;D Saves losing oil and also potentially stuffing the clutch slave cylinder. [beer] Title: Re: Ducati clutch push rod - spin or not? Post by: Mr.S2R on October 08, 2010, 01:57:22 AM yep, completely normal. well to be honest this is the first time I have ever actually changed clutch plates, dry or wet! As you said I didn't even take notice before, but will now. I saw a stainless steel item made by STM on the Motowheels website:when the bearing fails and the pushrod spins at the same speed as the pressure plate it causes major problems with the slave cylinder, always a good idea to change the pressure plate bearing to avoid that problem. bet you never even looked at how the pushrod and hat sat and moved before? paul. http://www.motowheels.com/italian/myproducts.cfm?parentcategoryid=442|Ducati&productID=2170&showDetail=1&categoryID=444|Clutch%20Assemblies%20%26%20Parts&vendoridtodisplay=0&filterFor=&collection=165|Clutch (http://www.motowheels.com/italian/myproducts.cfm?parentcategoryid=442|Ducati&productID=2170&showDetail=1&categoryID=444|Clutch%20Assemblies%20%26%20Parts&vendoridtodisplay=0&filterFor=&collection=165|Clutch) Is this a good idea? Thanks for your reply Paul. ;D +1 to that Paul. [thumbsup] I change my bearing every service without even looking at it!

[beer] yep I did that as a matter of replacement - the original bearing was still fine but I am of the mind to replace everything - which I must admit I haven't replaced the seals - but will do now! Cheers dragonworld! Next will be the clutch basket itself - it is not notchy, but I checked tolerances between the clutch basket fingers and the tabs on the plates - still within tolerance. Mind you with the Aussie dollar looking the way it is me thinks once back from the Island I will get a Barnett basket, pressure plate, new open cover..... [thumbsup] ;D Title: Re: Ducati clutch push rod - spin or not? Post by: Dannog on October 10, 2010, 12:40:24 AM I have the STM pin. Look nice!
