Allen bolt Underneath the seat area. 696

[DucNaked]

I see found the same place to put your frame stickers.

Yes.  There is on my M1100 and there definitely also was on my M696.

Damn I'll go take a bloody photo of it....  

Here....  No nut, but the allen bolt which is moulded into the tank has an accessible allen head... see?



into which you can insert an allen key to prevent it from spinning in the pastic.... thus..




Whilst this cant be seen   in DN's pic below...



...I cant believe they made 2 different designs, I'm guessing in the moulding process DN's and perhaps yours too got a thin layer of plastic over the top of the allen head hiding it?  Maybe have a gentle scratch around that area to see if you can reveal it?

Hey Ungeheuer, what is the part number listed on your tank.

[ungeheuer]

Only p/n for the fuel tank I have is from the M1100 service CD: 586.3.171.1A

Its the same p/n as quoted for M696.

Mines 586.3.171.1B   and it has USA stamped into it.

[ungeheuer]

aha.... so your p/n is the actual real thing.... whereas the number I just quoted is only that listed in my 09 parts CD.... I gotta go find that p/n moulded into my tank then, eh.  (Where abouts on the tank is the p/n located DN?).

Interesting that your is marked "USA".... I'm guessing that mine wont be.  Must be a different tank for gallons and litres  .

Or maybe they make em of a differently comprised plastic given the predominance of ethanol in the USA??

From memory it's on the bottom of the tank up near the ecu.

Both are valid part #'s.

Vinzer Uno probably has the new 'improved' version, while Ungeheuer has the 'discontinued' version.

I believe both ung and I have 2009 m1100s so the difference is I probably have the us version.

[ungeheuer]

Yup - my M1100 is a late (Nov or Dec I forget which) 09 build.  My M696 had exactly the same tank design and was an early 09 build.  I'll check its actual p/n and report back. 

[ungeheuer]

So I removed my tank just to check the p/n for y'all.  You're welcome  .

Part number marked on mine is: 586.3.171.1A the same as listed in the parts CD.  No destination marking tho (I half expected it to have EU).  Its interesting that Ducati seems to have at least 2 tank types one for USA and another for..... everywhere else?  Now why would that be?

[ungeheuer]

So I just revisited the parts CD.  I always choose the "English" version (but I just checked the German too) and here the fuel tank is listed as 586.3.171.1A.  But when you open the parts manual via the US icon.... tank p/n is listed as.....  586.3.171.1B.

Why is it so?

[liquidsmile]

Some of the EU tanks have different vent configurations, for emissions.  The plastics on those tanks are the same, trust me. Also sometimes part numbers are made different for when a change in mfg comes in to play.  The 1098 has actually 3 different part numbers for the radiator with only one physical change on one of the  parts.

As far as your problem with the tank, if the nut is stripped and you cant get it out, take it to your dealer and have the tank replaced under warranty.  If they won't do it bring it to me, I will.

USA tanks are designed to comply with the ARB of California.  the difference is a blow line for the vent canister.

USA EPA also has SHED testing which tests vapor emissions from the tank.  There may be slight variations in the construction, but as far as I have seen, they are all polyamide (nylon).

[ungeheuer]

...as far as I have seen, they are all polyamide (nylon).

Hmm... so what do you make of this? Here's a pic of my 09 M1100 fuel tank (non-US market)...

...which as I'd suspected, is made of a different material; XLPE = cross-linked polyethylene.


And here again is DN's 09 M1100 fuel tank (USA type)..

.. made from PA = polyamide (nylon) just as ducatiz has already said.

So why the difference?

[ducatiz]

What market is the xlpe tank from?

I have pics of UK tanks showing nylon (pa) composition.
