I’m watching these videos a decade after they were made; getting ready to tackle a monster 821. Best videos by far; very clear and great detail. I wish I could’ve warned you about Covid
@DUCASBK I agree If the 999 is like the 1098 (I assume it is) then the "T" on the cams for the vertical cylinder should be reversed. When Chris checks tension on the vertical cylinder it looks like it is TDC at the end of the exhaust stroke.
You are right. Take a look at the cam ends on the horisontal sylinder. They make an upside down T, at TDS. Should hve turned the engine 270 degrees forward instead.
What's the idea of rotating the engine backwards 90 deg? What's the other method without the crankshaft turning tool? I remember putting the bike in gear and using the rear wheel.
I'm having a really difficult time getting the belt to go over the cam. It almost seems like the belt is slightly too small. Im using a cam holding tool as well, but it just doesn't want to slip over. Anybody have any tips? Its driving me crazy
I get why you're marking the belts but I honestly don't see the necessity of doing so. When I did my 1100 EVO I marked the crank in relation to the mark on the case and each of the four cams to a point on the valve cover/cylinder head. As long as those marks all align the same once the new belts are installed it's good, is it not?
Hi Rudy, sure, yes. Marking the belt is a great extra step to visually check a cam didn't move. That's why there are lots of ways to do the same thing and this is what we do.
So you chose not to place the vertical to TDC, as long as the crank has not moved. The way I understood from other sources is to place the vertical to TDC so cams are properly aligned, place vertical belt then go back to horizontal TDC to replaced horizontal belt. your method is easier? bit confused.

I doubt the dealer is checking the tension the way you do!!! Is it normal after the timing belt changes,,,,that is sound like I have a chicken in the engine??
ducaking We have heard of customers experiencing squeaking after a belt change with our belts so we say on the label to tension them to 99hz instead of 110 to help alleviate that symptom. They are safe at both tension frequencies, but are quieter at 99hz.
***** It seems like the noise has disappeared. I just paid a 1300$ MAINTENANCE bill the other day. I'm a bit paranoid.. just the 15000miles maintenance!!!
ducaking Don't worry, if anything ever happens to those belts we will take care of you, but we have been selling them for 5+ years with great success. Glad the noise disappeared :D Happy riding!
***** I'm a bit far to go and see you!! I'm in Montreal Canada and there is only 2 Ducati's dealer in the whole province of Quebec... Still, I'm working on learning mechanic...
I take it you know the cams themselves need locked in place & the cam pulley bolts loosened when the belts are being tensioned so the cam timing is correct when you are finished.
+Brian Jones (Moto-Tech) Hi Moto tech, yes, that's how Ducati says to do the procedure -- I applaud the factory for coming up with a method which eliminates "feel" and minimizes the attention to detail required for the task. My video is a presentation of how *I* have changed the belts. I take it you didn't see previous comments similar to yours or listened to when I said this is an alternative to the factory method... -Chris
+Sergey Velet thanks for your thoughts. Some of these were filmed before cell phones could even take pictures! Also, my intention is to help introduce the process, not to create technicians. My thought is you watch the video, read a service manual, and sit in front of your bike, then you can decide if this is something you wish to tackle for yourself or take the bike to a technician.

I think I've watched this set of video almost 10 times. It's intimidating trying to read the right tension!

Thank you for the feedback! We will look into that brand and see if we can carry the tool!

Violin kulcsot kell használni a Ducatihoz, de nyomatékkulcsot nem. Szolfézsra is kell járni a ducati szerelőknek? :D :

Lol it is impossible to see what the tension frequency is on your thing !
+2218alex right? Yes, it is difficult with the arrangement I was using. There are non-free tools available which may provide a more lasting read-out.
Thank you for the kind works :)

270 degrees forward is the same as 90 degrees back ;)
wish you could explain things better in more detail and offer better quality and more professional videos instead of a cell phone quality audio
