Testastretta Engine Build Video 4 - Fitting the timing belts

In this last video of the mini series following the Testastretta 749 engine I fit the belts
This is different technique to the earlier desmo engines as all the Testastretta engines in the 749, 999, 998 and 996R series of bikes can use cam locking tools to set the standard timing position to allow the belts to be fitted
This video follows the process of setting the tools up to fit the belts and then tension setting the new belts

Firstly I'll say I'm subscribed and I enjoy all the video's and are a good source of info for heaps of us, however this belt install procedure has an element missing I'd consider important. The factory cam tools have locked in the cams to clock them at TDC but you dont have the crank accurately locked at TDC, I believe there is a factory locking tool for this as well. Cams could easily be advanced or retarded to TDC, without the extra tool. JMO :)

[@DesmoWerx]

You are correct there is a tool to hold the bottom end in place, however its quite hard to turn over the bottom end without the turning tool once its built up and I do this often enough that I am comfortable in the way I am doing it. Pre 749/999 there was no tool and that's how I cut my teeth doing it. That being said at only £40 its worth buying the tool if you are doing it yourself.

[@TOT4Lpsychose]

Hi DesmoWerx, Great video. Question : shouldn't you have measured and adjusted the tension of the vertical timing belt with its cylinder at top dead center ? If not, why ?

[@DesmoWerx]

You are correct the manual states TDC for both cylinders when checking the tensions. I have found very little difference when measured this way and the correct way, I suppose I became lazy I will make a video to show the factory method to clear that up

A question, I have a 2004 U.S. base 999 with a bad rear cylinder, moisture in the cylinder. Can the later 2005-2006 999 or 999S cylinder be used on the earlier 2003-2004 999? They have different part numbers but the cylinder head part number is the same for 2003-2006.

[@JH-rz2vf]

Hi, very usefull video. I made the belt replacement in a Monster 821 following the manual and it is exactly the same procedure, but I got a question. I can adjust the belt tension to 110Hz but when I make tight the little screws from the pulleys and I take out the pulleys locking tool, if I turn a few times the cranksaft and I measure the belt tension again it is around 140Hz, is it normal? I am thinking about adjust the tension to 110Hz just moving the tensioner, lather on a few crankshaft turns, and measure again, what do you think? Thanks again for the video!!

[@Pirateshipwright]

G’day mate, I’ve got a 821 as well and about to do belt change soon. I’ve also go the workshop manual. My question is, is there any thing you’d like to point out that I may struggle with? Thank you

[@chrishard7616]

My thinking is there will be some additional force on the belt from the spring tensioning on the valves once the sprockets have been tightened back up. When the sprockets are loose and locked with the tool this force would not be there. I guess if you know it adds a bit of tension then you could set the initial frequency at the lower end to start with. When you ran the motor did you leave it at 140Hz and if so did it make the belts noisy?

I have a 2014 1200 Monster. Is the procedure for changing and tensioning the belts the same for all Testastretta engines ?

[@DesmoWerx]

Its very similar across the range, there are differences in cam positioning depending on engines and the main difference is for DVT engines.

[@TheCooperville]

Hi Nellie I love the videos they are great resource. I am wondering if you can do a cam timing video for dummies on the 848/1098?

Help mi sir my Ducati 848 evo time Balt tension please sir help me

[@DesmoWerx]

What help do you need?

[@swagger897]

Hey there. First video I've seen a tool like this that locks the cams instead of the pulleys. I tried a method similar to that of Mr. Kelley's way, rotated each cylinder to TDC, marked the belts, counted dots between marks, transferred marks to new belts, installed the belts with the marks matching both the pulley and the new belts. I've ridden the bike only twice since, both times less than 15 minutes. Lately though I've been unable to start the bike, and part of me now questions whether or not the method I used was correct, or if the tension has been held by the eccentric pulleys, as I reused what looked like a new fuji nut. I assumed that with all the gaps between the marks there should be no difference in timing, would you agree to that? If not, I might need to pick up a set of these tools and figure out how to properly time the bike. I'm sure that I'm getting fuel (unsure of PSI) to each cylinder, spark to each cylinder, but compression and timing is still unknown to me at the moment. Hate dumping questions on people's videos but just trying to get ideas as to what may have gone wrong...

[@DesmoWerx]

The methodology works for aligning the new belts with the position of the old belts, you can put the timing out by over or under tension of the new belt but this would alter the timing by only a couple of degrees which would unlikely present the issues shown. If you had the the wheel move by a tooth though this would be a larger margin of error in timing. I would check the timing to eliminate this as a potential cause but would also check all the other basics such as, plugs, air filter, coil connectors, ignition pick up etc

[@swagger897]

@@DesmoWerx The layshaft always had the mark between the case and itself lined up throughout the belt change. I switched from copper electrode to iridium plugs since and I'm thinking this is my problem. Waiting on the oem champions to arrive to be able to install. I doubt it is timing, but will look again.

I have never seen those cam holder tools, they are really cool!

Hi Greg, I got them from Ducati Kaemna in Germany

[@richroberts8238]

Wow, did not know about the cam pulley tool. Chris Kelley is a good friend and having watched his videos on testastrettas found the failure of pulley marks to be a line up method not very reassuring. Old desmoquatros were a piece of cake. Looked up tool on Ducati Kaemna and then found one new set on eBay. Damn good tip. Thanks, Rich

[@DesmoWerx]

Hi Rich, Glad the video was of use to you, I try and take the mystique out of maintaining our lovely bikes. You can align the timing marks once you have the tool in place if you want so you have another method, I never bother as I always use the tool to align the cams initially.

[@chrislee7817]

Bit worried that the timing marks didn't line up 😱. Why was that?

[@DesmoWerx]

Hi Chris, It doe not matter as the timing is set by the tool not the wheels. You can align the wheels to check timing marks against the head cover joint if set correctly The owner of this engine is happy to time off the cam tool rather than the wheels so we did not reset them To reset them we could have timed the cams, them completely loosened the pulley wheels and re-positioned them to use the marks if needed. He brings all his engines to me so is not interested in changing the wheels.

This is probably a super simple question, but how do you know the belts are on the right teeth in the centre pulley?

[@DesmoWerx]

Hi Jamie, there is a location marker for the lower pulley to set at horizontal TDC.

[@v12dot]

Am I right in saying the t cam marks on my 1200R all line up with the heads on both cylinders at TDC on horizontal ? If so can this tool be used on my engine ? Cheers , Stewart .

[@DesmoWerx]

Hi Stewart, There is a separate tooling set for the 1200 set of engines as the timing belt process differs to the testastretta's. The tool needed is part number 887651623 Can be found here www.desmo-racing.com/en/belt-roller-timing-tool-ducati-887651623-xml-363_423-5815.html I don't have a manual for this bike so can not confirm the full process as being identical

[@DesmoWerx]

Just found out that the T should all be in line and inverted on both the vertical head and horizontal head when you are at horizontal top dead centre so you are right in your assumption. i.e. _I_ _I_ pointing towards their respective head cover for both sets of cams. Hope that helps

[@DesmoWerx]

Thanks Mark, glad you like the videos. Yes you loosen the grub screws to align the belt teeth as the timing tool holds the cams in the correct position for standard timing :) Just remember to tighten the screws up to correct torque before removing the tool

@milkster100 Hi Chris, I got my set from Ducati Kaemna, if you search them they have a good website with performance parts. 😎

[@judokezza1]

Hi. Great videos. If I lay a straight edge across the flats of the cam shafts (where the ducati tool aligns the cams) would this confirm they are in the correct position? Thanks

[@DesmoWerx]

Do you have the belts off yet? If not you can mark the wheels against the cases whilst the engine is aligned correctly. Better than using a straight edge

[@chrishard7616]

But that goes against the whole point of enduring the camshafts are correctly reset using the tool. It’s possible over time and depending who last worked on it that the sprockets aren’t in the exact correct position. Using the tool resets it correctly.

[@chrishard7616]

Nice video. That is how the Ducati W/shop manual shows how to do it with those tools. It's the same principle as used on VW TDI engines, as it allows for perfect re-timing of the camshaft/crankshaft relationship. Also, it removes any influence on the belt from tension/friction caused between the shafts. This prevents corruption of the frequency measurement, since the camshaft sprockets are free to move during the procedure.

[@DesmoWerx]

Thanks Chris 👍😎, The cam tools certainly make it a lot easier than the earlier methodology and is more consistent.

[@frankbutaric3565]

The only way to ensure perfect cam to crankshaft alignment is to degree the cams to crankshaft. There are tolerances in every single part and tolerance stack up is always present especially on the distance between crankshaft and cams. This is the reason that some bikes make more power than others. It is also the reason that Ducati engines rarely have the cam degrees where it should be. They are usually off.
