Rear mudguard screws

Does any one know what the metric thread size is for the rear mud guard screws? I busted one of those screws off in my swingarm, its going to be a challenge to get it out. Im trying to find out what that thread size is in case i have to use a heli coil. Thanks.

Iíll have to take one to Ace hardware and find out for sure.

did you dload the Spare Parts Catalogue? it has the part number in it...


M5x9 I believe it is, 3 part numbers for the same screw depending on the year of the bike - the latest part number is 77214411BA

bummer

seems to be a common occurrence. i broke one off while changing to a carbon fiber rear hugger. so for the time being i'm huggerless. i've ordered a few of the screws from ducatiomaha.com. want to make sure i have a backup. i think it's due to the red loctite they seem to use.

No, I havenít downloaded the spare parts catalogue, I will look in to that. The parts diagrams I looked at gave the part number but no description as to what the thread size is. Hopefully I can get it out without damaging the threads.

Yeah, I bought a couple spares at my dealer. Itís totally my fault, you are only supposed to torque them to 5nm, thats not very tight. I would normally just have used a hex key but I had my 3/8 ratchet sitting there and used that. Lol... they break very easily. Hopefully i can get it out easily, not much room to work in there. The one I broke is one of the back ones under the exhaust loop.

Good to go

Well, I got it out without damaging the threads so im back to normal. It was a tight squeeze in there but it all worked out. I used the right angle attachment for my dremel tool, i got some high speed steel jobber length bits and still had to cut them down to fit in there. Just a tip if you have never done this, torx bits make excellent screw extractors, thats what i used, i ground a lead in chamfer on it, worked like a charm. Today was a good day, got my screw out, got the akro slip ons installed and new rosso corsa 2ís.
