Title is where you can get a parts manual & online exploded view of just about any late model... didn't see much past the 80's though.

Not sure I understand? This bike is from 2010. Googled for a parts manual and found this though https://docs.google.com/file/d/0B4sSBYkFYLhvS3FBVUxjQXY0X3M/edit?pli=1

I'll have to study it this weekend.

I asked the Amsterdam dealer for an appointment Saturday or Tuesday so hopefully can get some help too. Same response at first "must be the bolt above it" and "probably not oil, probably grease from the factory".

Bolt above was replaced last week. It's definitely oil.

Marlene: the bolt you are circling is the actually a nut - its a cylinder head nut and the threaded part is a long stud. It doesn't "hold the engine together" exactly but it does hold the head on the cylinder. There is an oil passage the runs immediately above that stud in your motor, and the likely source of the issue is a small issue with the head gasket or bush that surrounds that passage in between the cylinder and the head. What would be interesting is to know what the last mechanic actually did there - you said he "replaced the bolt" but nothing about that bolt is important so wonder what he did.

Going to the dealer is a good idea since the bike is so new, but if it were me I would get a new gasket and replace it - not a hugely difficult or costly job. Part number is 786.1.098.1A for the 2010 M1100 (same as the S) US model.

If you want to see what I am talking about go to the Ducati Omaha site like previously suggested (http://www.ducatiomaha.com/products.asp), scroll down to your bike (2010 M1100), and scroll to page 25 of the parts listing (drawing #7).

The bushing that directs the oil is part #7, the gasket is part #10, and the bolt you are showing us is attached to the stud that goes through the hole just below the bush.

You can see your cylinder head on page 37, and the stud, washer and nut on page 31 (parts 6, 7, 8).

ps. the manual you downloaded is essentially the same one as online at Ducati Omaha, page numbers are different. For the first page I mention go to page 40 in your manual; to see the stud and washer and bolt go to page 46, and for the cylinder head go to page 56).

pps. Replacing a head gasket on a ducati motor should not be expensive....the older bikes were even easier but I'd say maybe an hour's work, tops...gasket at ducati omaha was pricey at $50USD.

Hi Mark, Thanks a lot for the detailed information. ;D

I managed to follow your instructions to read the diagrams but I am really terrible when it comes to matching the diagrams up to my motorcycle. Probably because I've never opened up a bike before.

Luckily I've got a friend who has and who can help me next week. I am going to print a copy of the manual and take it over with the bike and see what we can get to. I will take photos and post updates.

P.S. Any idea if I'll need special tools for this? I have the standard array available but I mean special from the Ducati page of tools?

 

[marlene996]

Mike - I'm just looking at the manual pg 31 for the stud, nut and washer, and I'm confused because it looks like in the drawing that that stud goes through the crank case half first and on the left hand side of the bike (if the right of the page is to the front of the bike).

But the leaking stud/nut on my bike is on the right hand side and to me it looks like it is right in the cylinder head. If I compare that to the diagram it looks it is coming from the hole shown here:

 

[markk900]

Hi Marlene: there are 4 studs - two on each side, but probably the same part in the diagram. And yes, that stud goes through the hole you circled and the nut and washer tightens it down.

The diagram you show is the top (cylinder head), the one I referred to on page 40 is the cylinder (in the middle) and the cases (bottom) are on page 46. The studs squeeze the cylinder in between the cylinder head and the cases (like your mechanic said - in a sense holding the engine together).

Also if you notice in the picture you posted, no hole above that one. But in the cylinder picture (page 40), you'll see the bushing etc above that hole. So the oil passage ends in the cylinder head, and your leak is likely oil making its way from that bushing to the stud, and leaking out under the nut and washer you originally pictures.

You have to kind of picture things in 3D if you haven't actually taken them apart and seen it in your own hands....

Oh - I can't speak definitively for your bike, but I don't believe there are special tools. You will need to remove a bunch of stuff (carb, exhaust, etc), then remove the belt from the front cylinder (there are marks that need to line up before you do that so do your research), then the cylinder head itself (generally just the 4 nuts you already know about). Replace gasket, reverse the disassembly process to put it all back. If you and your friend are confident, no issue. Otherwise get a mechanic to do it.

Hi there. I believe that the nut and stud where the leak is coming from is the stud that holds the head AND the cylinder to the crankcase. The leak could be getting there via the headgasket OR the cylinder base gasket (not unknown) then along the stud and out through the threads on the nut. This will involve a considerable amount of work to replace both gaskets to ensure you have cured the leak. To avoid expense and disturbing the engine, can you live with this leak? It doesn't seem too bad from the pictures. It may even get better. Of course if it gets worse you will have to take off the head and cylinder to change both gaskets. Hope that helps.

 

[rolandantrobus]

In my experience these type of oil weeps are caused by owners, or previous owners, gunning the engine before the it has fully warmed up. The alloy heads and cylinders need to expand fully to seal the gaskets before full power is applied. A substantial all alloy engine like the Ducati will not be fully warmed up for at least 17 or so miles.

 

[marlene996]

Hi Roland, thanks for the info! I know better than to gun it cold but I didn't know about the details of why.

I can not live with this leak because from two weeks ago I couldn't barely see it and now it is very obvious where it is coming from, so it is getting worse.

Won't be able to do anything about it til Wednesday/Thursday but will update then.

Still leaking?

 

[marlene996]

I left the bike at the dealer a week ago. They finally got around to it Saturday. The mechanic said he let the bike run until the oil was warm but it didn't leak. Then he rode it for 10 minutes and it was pumping out of that through-bolt/nut spot. So he came to the same conclusion I did.

He is going to order the head gasket and a cylinder gasket and replace both. Hopefully the parts come in this week and it's ready Friday but I won't hold my breath.

At least there is some progress. [thumbsup]

Such nice weather now and no motorcycle

 

[markk900]

Ask him to save the gaskets and show you where the leak was coming from when they do get changed out.....free education!

 

[marlene996]

+1, Oh good thinking, I almost forgot that!

 

[marlene996]

Okay, I finally get a chance to update this!

When the mechanic took a look at my bike he came to the same conclusion that we did earlier, the head gasket was leaking. He said when he let the bike run for 15-20 minute to warm up the oil he didn't find any leak, but after he rode it for 15 minutes, he could see quite obviously it was coming out the through bolt.

Since he was going to replace the head gasket he also wanted to replace the front cylinder gasket and I agreed.

In the end the salesman who sold me my bike proposed the shop would pay half the repair cost. He said even though my bike was well out of warranty he didn't think it was right to let me pay the whole cost of repair when I didn't put that many kilometers on it. + + +

So my cost in the end was €113 ($150).

I was annoyed by how long it took to getting around to looking at the problem, but to be fair I brought the bike and left it without an appointment in the beginning of nice weather and riding season (they were really busy). Once they knew what was wrong and ordered parts it was ready in a few days. Overall I am very happy with the customer service at Motortoer in Amsterdam.

Mark Here is a picture of the parts replaced, I'm pretty sure these are the gaskets we look at in the parts diagrams:

And a picture of me riding home in the: nice-sky-rainy-sky-dry-sky-hail.

 

[markk900]

Those are the ones Marlene! Glad you got it sorted and $150 isn't super bad for that work. I could be mistaken but the silver one appears to be the cylinder base gasket and the brown one the cylinder head gasket, and I'd definitely bet on the head gasket to be the one leaking. Doesn't take much of a gap to let a lot of oil through. Your mechanic was right to replace both as 99% of the work is done once you remove the head - might as well replace the base gasket at the same time.

Get out and enjoy that Dutch sun!

 

[rolandantrobus]

Glad to see you got it all fixed. Also pleased to see both gaskets look to have been leaking. Means you were right to get both changed. Hope that's the end of your probs, looks a nice bike!

Glad ya got it fixed before the really nice weather hit.
Nice bike & rider (Love the curls out from under the helmet)
