Any ideas how to undo the lower shock bolt
 

As per the title

Been struggling for a couple of hours to undo the lower shock bolt on my 1100 Monster, tried the air gun and 600mm long breaker bar and all I have managed to acheive is two spiral 8mm Hex keys and a marked footrest casting and the bolt is still solid.

The bike is less than 2 years old has less than 9k miles on it and wasn't used through the winter.

Decided to try the 750mm breaker bar and a 3rd 8mm Hex Key
Managed to shear the Hex Key, so the costs of trying to undo this one bolt is mounting up

Maybe I should see if I can get the bolt replaced under the warranty, although that doesn't help at the moment and at the same time see about the alloy corosion on the front headlight

Did type a follow up thanking Kev P for his help
Then when I posted the reply I got the Sit Busy message and lost it in the ether

It sounds daft Kev but, left hand thread ?
Stranger things have happened.

Well now I have seen it all. Skids posting up a "How do I"
I have lived.

Nope Neil not a left hand thread, not even a nut to worry about
A 10mm Bolt passes through the swingarm casting through the shock eye and threads into the swingarm on the other side.

Craig it pretty much turned out to be a two man job, what should be a fairly simple job is made a lot harder by Ducatis use of nickle plated Steel bolts and fitting them into alloy without the use of any anti-seize compound.


Kev P came around with some more 8mm Hex keys which we then managed to trash including the Snap-on one

In the end we got it out with me heating the swingarm with the heat gun adjacent to the thread area and Kev attacking it from the other side with the Windy gun
Once the bolt was removed there was no sign of either thread-lock or Anti-Seize compound. So the problem was caused by corrosion, needles to say when I refitted the bolt after cleaning it with scotch-brite I gave it a liberal coating of copper slip

So the answer to the original question is

Six 8mm Hex Keys required
Windy Gun required
10 Bar Compressor required
Heat Gun required
Two people required
And how ever long it takes

I too love the steel bolt, alloy combo.
Undoing something or other (footpeg?), the other day, I needed a breaker bar arrangement on the allen key ... the thing finally let go with an ear-splitting crack and a distinct spark. A spark! Crazy.

am glad my suggestion to senna when he phoned worked then skids :)

Yep Alan
by the time Kev phoned you we had tried everything bar the heat, mainly beacuse I didn't want to damage the finish on the swingarm.

But as you suggested you can't do it without it,
do you report these sort of issues back to the Factory or Ducati UK or just live with it.

Only a slight mark left on the swingarm from the heat gun
So I may have to go for a nice Carbon swingarm protector

Well thats it then I'm now officialy at stage one then Kev, managed to round it off on Sat, jes its well stuck in there. Next job put the tank back on and ride it down to Pro Bike and get them to get that damm bolt loose.

Craig

They'll have fun then if its rounded off,
They will probably end up drilling the head off it and try punching it out the other side.
Be better if they drill it from the thread side as thats into a steel insert and less chance of enlarging the hole in the Alloy swingarm

You don't need 10 bar for your impact wrench. They work on volume of air not air pressure. All you do is **** the wrench quicker if you use it above 90psi (6 bar).

I like the link to a cartoon of yourself skids?.. Red bike , yellow leathers, mid wheelie, sticking 2 up to the man!:lol:

Good post Kev, I hate ones that finish without a solution

"Nearly all men can stand adversity, but if you want to test a man's character, give him power". Abraham Lincoln ...53 horse power should do it.

As I didn't want to go and spend the best part of £600 on a new compressor with a higher volume than the 30CFM and 270 Litre tank one I have in the garage and upping the pressure was possible then thats what i opted for and it did the trick and got the bolt out.
A New Impact wrench would be a lot cheaper to replace than buying a new compressor but I don't need to as the Impact Gun is still working fine
