Timing belt renew- 06 s2r1k- is this a dealer only job?

[J.P.]

Couldn't find anything other than the Duc computer w/ optional acoustic p/up is required.
Will a guitar tuner or somthing work? What do you guys do?
Hate going to the local dealer- won't see it again for months. Anyone know if Richmond (VA) Superbike has one still?

Computer with a mic will work fine. The guitar tuner... whats the lowest note it can detect? I would think ~100hz is pretty low maybe a bass tuner would do better? or a bass and guitar tuner? or really, even a cheaper option would to buy a tuning fork that is the recommend hurtz. which is 110 i believe.

Just use the 5mm allen wrench trick..I dont see what the big deal is about this acoustic garbage for a 2 valver..for a 4 valver I can see that as an a possibility with is multiple cam gears..

Personally if you go by the book (i.e. the ducati owners manual), an oil change is a dealer only job.

the problem is the 5mm trick *supposely* does not work for the DS1000.

After reading about others experiences on this forum (Thanks!) I bought a microphone from Radio Shack - says freq response is 100 hz on the low end - but it measures lower - and downloaded a couple of free programs.  AudioAnalyser V1.9 and Voicesync ETG sound generator for testing the setup.  I ran the tone generator and what it produced (belt low limit of 70hz worked fine) and what the sound analyzer measured agreed.   There are probably better programs but these were free...   I was able to measure my belts even though I couldn't hear them - front belt was right in the ballpark, rear belt measured about 70hz

And THATS the problem. "Supposedly"...Its tried and true method for almost 10 years. I'd hate to throw out a method based on supposition. If anyone has any concrete proof, please speak up.

Is there a difference in terms of belt frequency from non DS1000 bikes?

Heres another thing we can do, if you get a dealer to tune it "correctly" then try the allen key trick on it, that allen key should be the correct size for all belts. just do it when the temp is cold or the bike is warmed up and make note of it.

Ive personally tried a 5mm key on mine, i couldn't get it in there for jack no shit. But that was factory 147hz tight. I got it retentioned so it should be at the "correct" value now.

[Speeddog]

To get some meaningful results from this thread....

Don't measure belt tension at some unknown 'warmed-up' temperature.
Let the bike sit overnight, so at least you've got some reasonable idea of what the temperature is.

You mentioned you couldn't get a 5mm key through with the factory 147 Hz tension.
Did you verify that 147 Hz?
What size key *did* fit?

What frequency are your belts tensioned at now?
What size key fits?

IMO, Ducati went with the 'frequency' method to make the tensioning consistent/repeatable, as all dealers would use the same testing instrument.
This takes the 'skill' and 'feel' out of the process.
Whether the official 'frequency' tension is correct or not seems debatable, as I've heard of a significant number of tensioner roller failures.

EEL has an excellent point, there's been thousands of 2v ducs run with the belts tensioned by the 5mm allen key method.
From what I've seen in the last 5+ years on TOB and here, belt failures are very rare, maybe 5 or so during that period, and IIRC most were probably due to foreign object damage.
Perhaps someone with a better memory can chime in.
If it was really super-critical, IMO there would be lots of belt failures.

good call on the cold engine.

I had a 3mm key fit through mine at the time. 5mm was impossible. i did not verify the freq of the belts. I did mine cold, this was back when i first bought the bike with less than 5,000 miles on it. The bike was sold to the previous owner as a demo bike with the 600 mile already done. I believe ducati sent out the new specs in 07. and the bike was sold with the 600 mile back in december06/jan 07. Thats my assumption on the old specs.

I really don't know what my belts are tensioned at right now. They seem to be tight enough to not slip. I will check what key fits tomorrow morning and post it up. i have a guitar tuner around the house somewhere and ill see if that works. I have a set of DS1000 timing belts that need to installed and i was just gonna buy a mic and use some PC software as suggested by chris on TOB

pretty good info about the new method.

[Howie]

I believe Ducati has reduced the frequency specs due to the bearing failures, and may be arount the area of 114 hz.  Maybe someone could check with their dealer?

According to my source. a Duc tech with 10 yrs experience, the 5mm key does not work on the 1000 cc motors.

The span between pulleys is totally different and will leave you with very loose belts.

Ok, so i like speeddog's idea then. Lets find out what allen key works for the DS 1000 motor. Someone set it to the right frequency and post the equivalent allen key. Would be a great help to the board.

Here's some work done previously, maybe this will help:

Sorta funny finding this here just now.  I've just finished doing the belts on an 06 S2R1K.  did the horizontal one twice, as the tensioner's bearings cooked off and welded themselves to the tensioner, eating 75% of the belt beofre I cought the issue.  Thanks God I cought it before it broke. 

The problem with using the 'old' method here is that the old method is for the 'old' belts and while they use the same tensioner now (Ducati superceded the 1100DS tensioners for the 1000DS anyways, so I now have one vertical tensioner with bearings and clip, and horizontal tensioner with integrated bearing that is smaller diameter, but seems to werk fine) are in fact different belts, with undoubtedly different tollerences.  It has been noted that the factory specs for the 1000DS motor would be WAY tight for the previous motors, but also that if you are to err at all, it's better to err on the side of loose.  When I replaced my belts (both times) I used the 45* method, which leaves the belts too tight for a 5mm wrench, but they aren't wearing, and the bike seems happy.  I'm sure they aren't wearing because in the next 300 miles I've checked the belts repeatedly to make sure I'm not losing anymore bearings.  I can't afford now piston and heads just now....  So....  There's always the 45* method!  And this, like virtually everything else within the 2V sphere is definately NOT a dealer only issue.  in fact, belt replacement is about a 30 minute job, start to finish.

However...  the paranoid part of me wants to know about this allen wrench thing...  If someone had used the frequency method, and cares to slip increasingly large wrenches through till she/he's figured out which fits at ideal tolerence, please post up!  I'm more than happy personally to check the 45* method against the frequency method.

Just as a warning, the 45* method IS the very issue SpeedDog was talking about.  45* where?  What exactly is 45* when you are just using perception.  45* garauntees that everybody's tolerence will be a little different, but then, in speaking to a Ducati mechanic, I've been told that the range isn't soo absolute, and err loose if you care to err....

Whatever, I just say, work on your machine, learn it, love it.

[Jethro]

I'm agreeing with Smokescreen that the 45ˆ method works. I replaced the belts on my M1000 using this method and have now done 13k miles on them. They are due for a new set but I'm not bothered about going a bit over the 12k miles so I'll do it in the winter.
I also agree with everyone who says that a 5mm key will not fit on the ds1000 engine- I checked after I fitted the belts and it was no more than 2mm.
I'm going to use the 45ˆ method again next time because it works for me and  I'm not convinced that Ducati have finalised the 'frequency'method.
