Ducati 1098S - Replacing the timing belts - Service Video No.1

[@alanr2609]

Watching these great tutorials it's apparent how much work is required to do even straight forward jobs on a Ducati.

[@DesmoWerx]

It does look intense but its not that bad really 😊

Great video as always, I have just picked up a monster 659 with 10,000 kms what you suggest about a belt change on it , is it time or kms the bike has had a easy life.

[@DesmoWerx]

HI Chris, do you know when the belt was last changed? If not I would change it so you know. Unless you are doing the mileage most belt changes are due to time period. 😊

[@frankgourdin9044]

Hi DesmoWerx Great video Thank you from France👍👍👍

[@DesmoWerx]

No problem Frank, glad you are watching 👍😎

[@nsrenkb9096]

Why did you loosen the timing locking screws?

[@DesmoWerx]

Its so that the belt can tension correctly, the tool holds the cams in the correct timing place but stops them rotating so you cannot tension the belt unless the wheels are loosened from the cams.

[@nsrenkb9096]

Great video. Be good if an alternative description given to fit/adjust belts if specialist tools not available!

[@DesmoWerx]

A good idea, I will look into sharing a different method on one of my upcoming builds/maintenance videos.

[@shanefrank3281]

Great video. I do have 1 question though. You have the tool that hold the cam pulleys in place so they can't move when the belt is off. But why do you have to loosen the 3 bolts on each cam pulley (you mention tightening them at 13:58). What is the purpose of loosening and then tightening them back? I see this mentioned in the factory service manual as well. Thanks.

[@victorsanchezhezari4189]

I would say that the tool helps so the timing remains the correct one when tightening the belts. I would like to know what is really the difference... I have never used the tool and i don't know if we are talking about 1 degree or rather a bit more so it really matters in terms of performance and quietness of the engine.

[@DesmoWerx]

Victor is correct, the tool holds the timing in place to factory standard whilst you tension the belt. The pully bolts are loosened to allow the belt tension to be adjusted whilst not interfering with timing.

[@bogdanpanici5010]

@@DesmoWerx thank you very much! As I see there is a lot of work and I am a beginner! I‘m still thinking if I have to try to do it by myself, or to bring it to Ducati , for 800€. Mine is a 848 evo, with only 1761km! Many said that I have to change the timming belt because of the time, the bike is 2011...what do you think?

[@DesmoWerx]

The belts will need changing if they have reached there life time even if not the mileage.

[@namir1782]

hi is it ok to turn the cylinders by turning the wheel or cold that lead to damage ?

[@DesmoWerx]

You can turn them via the wheel but it is not as accurate so may take a few attempts to line up the marks correctly. Make sure the plugs are out to ease the process.

[@calvinhutton57]

Question, you locked the position of the cams relative to each other which is fine, but how did you accurately find the position of piston tdc to time the now loosened cam sprockets to the crank?

[@DesmoWerx]

Hi Calvin, I used the timing mark on the lower pulley, as just aiming for stock position, if I wanted to time to exact degree settings I have a tool with dial gauge attachment I can use.

[@zappa916]

Brilliant - just in time for my service on my MTS1200. thanks

[@DesmoWerx]

Glad it helped 👍😎

[@parker550]

Hmm I'm assuming the cam locking jig tools are necessary for accurate cam timing adjustment? As most plebs, we'll me really don't have access to them or if I'm honest need, I'd go along with marking the belts in the tdc positions? And crack on, is this acceptable? And just a quicky is it better to check valve clearances with belts on or off? Thanks for your time.... Regards and great vids👍

[@DesmoWerx]

Hi Philip, the tools help maintain cam timing whilst you loosen the cam pulley wheels, this helps with making it slightly easier to get the belts on. You can replace belts by marking the wheels, old belt and then transferring the markings to the new belt to ensure it goes in exactly the same place. The tools assist with repeatability which counts if your doing a few of them 😎

[@jimccc9467]

Why did you need to loosen the cam sprocket bolts? Can you do a video on setting the lobe centers and where you place them for different power characteristics?

[@pierrelastra2285]

Super vidéo, thanks a lot. But i havé a question: don’t you have to remove first your timing tool before doing your belt tension measurement? Because the tool would affect the final tension, no?

[@DesmoWerx]

No need, the tool locks the cams not the cam pulley. 😎

[@jimccc9467]

Great video, thank you. I just got my first Ducati, an 1198sp with 15000 miles so it’s ready for belts. I’m a bit out of my element since my last three bikes were TZ250’s. Where are the cam locking tools from? Are they expensive? I don’t plan on doing this job frequently so may be cost prohibitive. Thanks again for great instructional videos.

[@DesmoWerx]

Hi Jim, the tools are from Ducati Kaemna in Germany, they are £200 odd for a set.

[@francescosimione1142]

Great video..... I just got a 998s I guess same Testastretta engine, as I was going to change timing belts and saw you have those good camshaft locking tools, was wandering where I can find them. Thanks, Francesco

Can you please explain what the device was to tension the belts,working off electric signal as i haven't seen it used before ?

[@DesmoWerx]

Hi Ger, it is an optical belt tensioner made by Clavis.

[@nlpx]

Just out of curiosity - are the pulleys for the testastretta engines compatible to each other? I was wondering if it is possible to replace the heavy pulleys from a 998 testastretta with something lighter from a younger testastretta engine?

[@DesmoWerx]

Its not something I have looked at doing, if the wheels the same size in diameter it would be possible. You can get lightweight wheels for the earlier testastretta engines.

[@Moosjwz]

Nice, very happy to see a new serie and helpfull to me with my 999 work. Did you had any issues getting the spark plugs out? On my 999 I feel I need a very thin 16mm socket in there.. I reach the spark plug just not the bolt

Great Video once again.... One more off topic question... what do you use for head gaskets and engine seals for your engine build projects? Athena or Ducati dealer? I’m amidst building my 1198 engine. Thx Again!

[@998RC]

This seems a lot faster and less potential for error compared to the method of marking dots on the belts. But you lost me when you said the cam sprockets were loose and need to be retightened?

[@Moosjwz]

He locks the cams with that tool and by loosing the rollers its much easier to fit the belt. Rollers are free from camshaft, so cams stay in place if i am not mistaking..

[@998RC]

@@Moosjwz Right. I just watched one of his earlier videos, so he just skipped explaining that step in this one. But I still don't understand why they need to be loosened. Won't the new belts fit with the cam pulleys in the same position?

[@DesmoWerx]

Hi RC, the tool locks the cams and allows me to loosen the pulley's which helps with getting the belts on far more easily than when they are fixed to the cam in position, there will always be a slight difference between each belt due to tolerances in manufacture so the tool adds with achieving repeatability in installation and belt position. You can also adjust tension without overly affecting the timing. I did explain it when I did the earlier 749 timing video which uses a similar method, apologies I should have added that step in this video as well. That's why I had to retighten the pulleys😊

[@DesmoWerx]

Correct Neven 👍😎

[@no-hope-in-the-pope]

for those watching..there is a much faster and easier way to change belts...take fingernail polish and mark where current belts are in relation to gears. Take belts off and count teeth to match new belts, mark new belts with fingernail polish, put new belts on and done! No need for any special tools or finding TDC!

[@mmm4638]

It slides out and in without loosening the tensioner?

[@herpderp1662]

​@@mmm4638 tensioner has nothing to do with the teeth of the gears, or the teeth on the belt if you count exactly how many its on. Tensioner just puts pressure on it, doesnt move the teeth from their grooves regardless how tight it is.

[@henrikviebke5691]

What a great channel! I have learned a lot from your videos, but I have a question about the cam locking tools. If your cam timing has been changed from factory settings (optimized), and you want to keep that setting, can you still use the cam tools and keep track of the new settings in some clever way? Best regards from Sweden 🇸🇪

[@DesmoWerx]

Hi Henrik, you could unlock the tool and relock to the cam timing setting you have on your engine before you remove the belts. The cam positioning heads are locked in with thread lock and a bolt so could be adjusted that way of you wanted.

Hey. How do you find the tdc on the vertical cylinder viewing the crank shaft pulley?

[@DesmoWerx]

Its another 270 degrees on from the Horizontal TDC, if you keep rotation in the same direction as the engine operates. I use a long screwdriver in the spark plug hole to check its reached TDC on vertical.

[@race5050R1]

Another great video. Thanks! Where can I buy the cam timing tools? I’m currently rebuilding my 1198 and waiting for my crankshaft to be repaired. Not sure how I’m gonna get the camshafts retimed without these tools when I reassemble the engine. Your videos have been sooo helpful... Thanks Again!

[@998RC]

I'd also like to know where to get the cam locks. All the places I checked only have the cheap plates that suppsedly lock the cams, but there are only gear cutouts for one side, so I don't know how they're supposed to lock both cams. As I understand, the factory tool fits in the "T" of each gear for completely positive locking.

[@DesmoWerx]

Thanks 😊, I get my cam locking tools from here www.ducati-kaemna.com/ you will need the specific tool for the 1198/848 EVO as it is different to the 1098/848 tool.

[@DesmoWerx]

The cheap plates do not secure cam timing but rather stop the pulleys moving which is a little awkward for putting the belts on. They can be a cheap alternative though.

[@998RC]

Hi Greg, I will likely put it up for £5500 or near offers.

[@hanitaa6323]

Hi Desmo, so to be clear, the tool you use locks in place the relative camshafts positions against rockers. By unscrewing the pulleys, you release the possible stress generated by the camshafts on the belts (tension of the belt is then solely related to the pressure of the tension pulley). To my understanding, this means, while you are tensioning to the correct frequency, that the position of the cam pulleys are subject to movement. This before you tighten them back. Additionally, both tensions (H and V belt) are different, hence the movement of the not-yet locked-back pulleys too. Am i missing something? Best regards, H.

[@DesmoWerx]

Hi Hani, Yes the tools lock the cams in place so you can adjust belt tensions with no impact on the timing. If you did not use the tools then when you tension the belt you would marginally move the timing. Ducati now use the same tension for both belts, they used to have different tensions per head on the older belts and bikes.

[@hanitaa6323]

@@DesmoWerx Thanks for the reply sir. I will try another one if you don't mind. I've seen different remarks on shims about their gap - on one side who would prefer resetting to factory default on the tight side for both open and closer like LT SNYDER, - on the other preferring hi spec for opening (0.18) and lo for closing (0.05), taking into account the natural evolution of wear (opening narrowing the gap and closing widening it). > what is your testastretta evoluzione point of view on the topic? > i don't get it, trying to understand this possible evolution of wear, concerning the opening rockers. Since to me this narrowing gap could only be created by valve seat settlement (and this should not happen normally?). Best regards,
