Thank you for very useful information.
...Hi Brad.<br />Thank you for very useful information. <br /><br />While working on my 996-SP, modified for racing with a SPS head, i find the original positioning on the tensioning wheel to be insufficient for maintaining belt tension. <br />With a new belt, the tension need to be at maximum, and the distance between the belt while running between the rollers is almost down to zero. <br />-Actually on the older belts I replaced, I could see the belt teeth had been in contact on the horizontal belt, but not on the vertical.<br />I rode the bike for 1 week in February this year at Jerez-Spain reaching 1200km at the track starting with freash belts.<br /><br />When looking at the belts after that, they where really loose, and not possible to tension up due to lack on cam-action by the tensioning rollers. <br /><br />I have now removed the outer and inner covers, and made new adaptor brackets moving the tension wheel a bit up and to the left from its original position. This gains approximate 1cm distance between the belts between the idlers, and I can fully maintain tensioning. <br />-Moving the tensioning wheel is not feasable with the covers on, so they have to be left off permanently. For the race bike its fine, and adds cooling ability.<br /><br />-I wonder if the poor tension was a part of the problem on the early 4V engines?<br />What is your experiences and advice? <br /><br />Thank you.<br />Lyder Moen.<br />Norway<br /><br /><br />Lyder Moenhttps://www.blogger.com/profile/12027682489955480846noreply@blogger.comtag:blogger.com,1999:blog-5762756769159510362.post-88150772622513955332020-01-03T00:47:58.635-08:002020-01-03T00:47:58.635-08:00Really Good tips and advises you have just shared....Really Good tips and advises you have just shared.

I own a Multistr...Thanks for the information Brad!<br /><br />I own a Multistrada 1100, 08' model. Bought it used 4 years ago with 41K kms and using it mostly for commuting - about 20K kms yearly. The bike is never abused, and is usually ridden mid-rpm, far from redline.<br />The bike has now 120K km on the clock, and it still runs quite well. I change the oil every 8K kms, and on this occasion I also adjust cam belt tension if required.<br />I change the belts together with valve adjustment at 24K service. Using ExactFit belts, I see no wear on the old belts. I feel a bit dumb replacing a part which has no visible signs of wear.<br />From your experience:<br />1. Do you think the cam belts fail because of time or mileage? How safe it is to run the belts for 40-48K kms in 2 years?<br />2. Every 24K kms my exhaust valves require adjustment - from maximum setting (I aim to a bit above 0.15mm) to minimum or a little bit below that (0.10).<br />Is it normal behavior for Ducati 1100 engine? Or it is sign of a problem?<br /><br />Thank you,<br />Konstantin,<br />Multistrada 1100,<br />IsraelAnonymoushttps://www.blogger.com/profile/16291384466477593029noreply@blogger.comtag:blogger.com,1999:blog-5762756769159510362.post-63793652017393564872019-01-26T19:06:30.606-08:002019-01-26T19:06:30.606-08:0010 years on 848 belts?10 years on 848 belts?tanken2https://www.blogger.com/profile/01024237531403181502noreply@blogger.comtag:blogger.com,1999:blog-5762756769159510362.post-67094015709956266062018-05-31T12:17:59.031-07:002018-05-31T12:17:59.031-07:00This comment has been removed by the author.JakeNichollshttps://www.blogger.com/profile/04282198701785222840noreply@blogger.comtag:blogger.com,1999:blog-5762756769159510362.post-88492212406290443232017-02-12T21:17:28.166-08:002017-02-12T21:17:28.166-08:00Great article.
I have just replaced the belts on m...Great article.<br />I have just replaced the belts on my S2R 800 for the second time (after 10 years and 15,000 klm). For the interest of other owners the original belts were replaced after 6 years and 12,00klm. My service handbook specifies a belt change at 20,000 klm. No mention is made of a time period. Is this over servicing? I suspect it is but given that no-one really knows how long the belts will last, at $120 for the belts (I changed them myself) it is a no brainer. I expect I will change the current belts in four or five years time and at the current usage rate the bike most likely will still be under 20,000klm and therefore, still not require a belt change (according to the Ducati service handbook).<br />On this same topic it appears that there is no way of determining when the new belt that you are about too fit was actually manufactured. It could already be two years old.carrinihttps://www.blogger.com/profile/02730161548310802074noreply@blogger.comtag:blogger.com,1999:blog-5762756769159510362.post-63892730449422834982017-02-12T02:04:05.655-08:002017-02-12T02:04:05.655-08:00Hi thanks for article very informative,I have owne...Hi thanks for article very informative,I have owned Ducati's for many years,I have a nice collection of bevels,2v and 4v.<br />I have changed belts around the three year time,All bikes have been ridden under normal Road conditions,with no problems.<br />I've just put a Gates T917 on my 92 851,The old belt taken off was a Ducati belt,red lettering but had next to Ducati Made in UK by Gates.Now that Ducati belt was 3x more expensive than Gates ones installed.Im happy to use Gates on 851 this bike will do approx 4,000 miles a year.<br />I'm interested to know your article mentions Gates belts in a negative sort of way,Did these belts fail due to high mileage,harsh riding etc.<br />Also what is your opinion on DAYCO belts as at one time I would not have entertained them but after speaking with Duc enthusiast's on continent they cannot see why I don't use them,as they are far cheaper In price than belts marked DUCATI but made by Gates.<br />I have now put DAYCO on my ST2 and 907<br />Many thanks Timbo DOC GB -Wirral Branch RepAnonymoushttps://www.blogger.com/profile/15113065020077934234noreply@blogger.comtag:blogger.com,1999:blog-5762756769159510362.post-2322864087547472182017-02-11T15:40:40.200-08:002017-02-11T15:40:40.200-08:00Really interesting stuff Brad. I came into Ducati ...Really interesting stuff Brad. I came into Ducati ownership after the belt failures but figured there must have been a reason why it was so tightly specified. Also matches with my 2V experience that you can let them go a bit longer time-wise than 2 years, even flogging them at trackdays. Something to do with the angles the belts are being turned around in the 4V coupled with a new construction in the belt that just meant they didn't last?<br /><br />No matter the reason for it, thanks for the timeline/history of it!everydaysciencehttps://www.blogger.com/profile/15622369028944578983noreply@blogger.com
