Fuel Tank Removal

its the difference between just bolting things together and actually fitting something correctly..... lesson number 6.

It’s a bit harder to fit something correctly when the subframe doesn’t line up with the frame…

There’s enough flex to pull it into position but, call me old-fashioned, I think it should line up without having to be stressed to do so…

I get your point with some stuff but a subframe designed to go with a specific frame should directly line up and simply bolt together.

have you morphed into SD?

perhaps out of the hundreds they have made you have got the wrong one? Id send it back.

So, to be clear, you don’t think you could or should have any reasonable expectation for a subframe designed and sold to fit a specific frame to have the holes in the right place to simply bolt on?

It’s not like this is a part designed for something else and you have to figure out how to adapt it to make it work - it’s meant to be for this specific purpose.

I don’t get your logic.

This clear enough?
Call them then tell them it doesn’t fit, stop bleeting on a forum and send it back then!

Or, Of course it’ll fit just like all the other parts of the puzzle you say didn’t fit… then fitted.

You like honesty! You are the problem here and your experience of doing this sort of thing … not the factory official supplier of parts and their years of history and quality!

I was not ‘bleeting’ (or even ‘bleating’). I was simply noting some issues, which were minor in nature, seeking to establish if others had these issues and checking for solutions before proceeding, rather than going at it like a bull in a china shop and potentially making a mistake or making the job harder than it needed to be. You seem to have a problem with people using the forum for advice instead of just figuring it out on their own.

And I said just a couple of posts prior that it will fit, which rather flies in the face of your above comment - it just had to be done with the frame stressed rather than simply lining up as it should. The lower cover fitted - once I had cut some plastic out of it… The subframe fitted, once I had stretched it sufficiently and held it there while putting the bolts in. So the parts didn’t really fit but they could easily be made to fit. Nothing particularly unusual but I expected something different, given their ‘years of history and quality’. I also don’t see why you have such a problem with me noting the issue and checking if it’s normal. You could have simply said ‘yeah, you need to hold it in position and it will be fine - perfectly normal and not an issue’. Instead you come back with your oft-repeated ‘its the difference between just bolting things together and actually fitting something correctly’. Super helpful for someone who, as you know, is doing this for the first time.

Which is exactly why I was asking on the forum - to benefit from those who have experience with exactly this…

In the shared spirit of being honest, your responses are very often antagonistic and unhelpful, when you could instead be helpful and pass on your practical experience (in this case, of fitting this exact part which isn’t exactly something lots of people have experience with). That’s what I would do if someone was looking for help and I happened to have experience that would assist them, but I guess we’re all different.

All of the things I have done to the bike have been the first time I’ve attempted them. Almost like there’s a first time for everything… At least I’m attempting these things myself and trying to learn.

If you think people shouldn’t seek information, advice and assistance on a forum then I’m not really sure what you think a forum is for. It’s supposed to be a community of people with a shared interest that help each other where they can. Others in the thread have made some helpful comments about the parts they know about and I’m not sure why you take the approach that you do.

Ok, I think this is the final bit.

At the top front of the subframe is a hole on each side that has a bushing and this is where the screw goes on each side to secure the fuel tank around the middle.

I believe I will need to push the entire thing through based on what I’ve seen on the parts diagram. The rubber bushing seems to be one pice.

Does anyone have any tips on the best way to push this through and reuse it without destroying it?

Parts 25 and 16. I guess removing both of the parts 25 would make it easier if that’s possible?

I don't understand how you could resist taking that valve cover off. Ducati uses a couple of different versions of that rubber thing. You won't hurt it. A little lube in the hole always helps.

So don’t try to remove the metal parts – just try to get a bit of lubrication in there and push it through?

Put a Allen bolt in it and push… bit of lube like wd40

About all that ..... talk about me fitting that seat…

Be careful putting those subframe bolts into the engine case under tension. That’s a recipe for cross threading. Would either bend it until it lines up or widen the holes. Either way I’d contact Pierobon and see what they have to say first.

Typical Italian manufacturing unfortunately…

Yes you are hanging around like them ..

The tips about using some WD-40 and pushing with a hex key worked perfectly. It actually pushed one of the metal bits out so I took the other one out and then pushed the rubber bit through and put it onto the new subframe.

The tank was a bit of a tight fit over those parts, but it wiggled on fine.

I remembered that this is aluminium and so I ignored the torque settings from the workshop manual and went hand tight, which for me is quite tight, with some thread lock on most of the screws.





I need to turn the bike on and let the fuel pump prime to make sure everything is okay. I was very careful with the fuel line and so I’ve left the original on.

The data logger fits in there very nicely. I had to bend the seat holder a tiny bit to line everything up but I don’t think that’s unusual from what I’ve read.

I need to figure out where to put the GPS unit – I bought a roof version, so that the cable goes straight down and I think I can put it on the bit that pushes in and is released with the key.

Really pleased with it and I appreciate all the help.

Someone was flush with cash but spent it all on Pierobon stuff

Torque those bolts, they are in bending and shear. The torque preloads the bolt with tension with the intent that it is greater then the bending moment being applied therefore the bolt isn't being cycled in use. Same reason they want you to replace them. Grease the underside of the heads first.

If you are referring to the four bolts that attach the subframe to the frame then I greased them and set them to 31nm. I also used new bolts.

I was talking about bolts that go into the aluminium subframe.

I missed this whole thread.

Can anyone summarize it ?

Spooky lightened his bike. Nice subframe but pretty pricey

Much cheaper to skip a few dinners and workout more if weight reduction is the goal.
