Put on new tires today and found this nastiness on my rear hub:

this has happened to you before?????!!!!
Not quite sure what we're looking at, but it doesn't look good :(
Need any help?
I told you to stop winding her up to ten grand and dumping the clutch. If you do you're gonna break those rear wheel retaining pins and now look what happened! [laugh] Do the matching holes on the rear wheel hub look OK? Any other S4RS owners experience this?? Swanny, Cory???
Not again... referring to the fact that I have to take her back to AMS for repairs and miss out on another few weeks of riding... but I should be thankful.
...
So, I take my bike over to a friend's place to do the tires... First thing we find is that the rear wheel nut comes off way too easily. Second thing is that the retaining pins are worn unevenly and one of them just fell off when I wiggled it. As I stared at that one I wondered if that could possibly be normal. To making things worse, I found the next pin was already cracked and was ready to snap as well. After close inspection, the inside of the broken pin had badly stripped threads and each of the pins had been worn unevenly, enough to do slightly ovalize the mounting holes on the wheel as well. We didn't have the parts or a hoist to allow disassembly of the rear hub so we put it all back together. With the wheel snug there was no detectable movement so I don't forsee any permanent damage, just those pins need to be replaced.
Perhaps that one damaged pin was stripped enough to allow some kind of movement, which in turn loosened the wheel nut allowing enough movement to wear down the pins and the mounting holes inside the wheel. I have a hard time believing the reverse, that the wheel nut loosened on its own and somehow stripped out the pins. Or that the pins are intentionally single use. I'm thinking overzealous assembly and/or weak materials.
...and on a safety note, thank god for the safety clip. I almost literally rode the wheel off.
it's odd that the wheel nut would loosen at all with the safety clip placed correctly. It wouldn't be a good idea to have the pins replaced. That should be a full hub replacement for safety
hmmm, time to sell that S4RS and get a 1198
Sorry to hear about the mechanical issues man... no chance of riding with on Saturday I guess?
Probably out another 3 weeks. :'(

Ouch, well that answers the email I sent you [bang]. Keep us posted!
damn, that sucks. how long for the new hub to arrive?
So far the repairs are pure speculation. I'll call AMS at 10 and let them know I'm coming. I have the bike on the truck ready to take in.
I'm so depressed knowing that I'll be rejoining the potentially long queue for service. I've only ridden a few times since getting it back the last time.
Is this in any way a warranty deal or is it coming out of your pocket? I hope it can somehow be construed as a warrany issue for your sake. Ouch, another three week wait. Sorry bro'.
hopefully by some off chance they have the hub in stock and it's an easy swap [thumbsup]
here's to a quick turnaround on the bike [beer]

The pin that fell off has stripped threads. If that was the cause then I would guess that it would be covered. Unfortunately, I'm out of warranty by about a week now, and who knows if they would cover it anyway.

I hope they don't replace the hub. I just want new pins. If there is something wrong with the entire assembly...
??? Wow - this looks like a serious problem - pretty high on the scary scale! Do registered Ducati owners get recall database access on Ducati's site ? I don't seem to find a recall notice thread on the main Forum - if there is not one a registered Duc owner should probably start one.

Here are a few old legal actions I found on a legal website searching Duc hub failure that I hope two of our Members ( 916 Owners ) are already aware of :

damn...three weeks. sorry to hear that man, though i can't say that's surprising at all. hopefully it ends up being something that doesn't cost you, besides not being able to ride your bike for a few weeks.
and thanks for the recall info; i wasn't aware there was a recall item on my bike. no idea if the parts on my SS in that area are still original. i wonder if AMS would check it out.
The bike is now in AMS' hands. Scott was kind as usual and says their backlog isn't so bad right now. They have the pins in stock. So, perhaps it will be done in time for the AR ride.
Glad to hear the bike is in the shop and in queue for some repairs. Maybe they'll bump it up since you have a big ride coming up [thumbsup]
I forgot to mention that to Scott when I dropped it off.

They should be able to fix it in under 4 weeks...
Any luck on warranty?
Patrick,
You gonna try and make the AR ride? Did I miss that post in the AR ride thread? If so, great!! Glad some more peeps can make this trip. That means a couple of folks don't have to be bored to death by my longwinded bullshit all by themselves. They thank you. [thumbsup]
I haven't been on a trip this year so I've got the itch pretty bad. I just put on new rubber in preparation for it. I just hope this repair doesn't set me back too far.
...
I think the AR thread disappeared for a while... shouldn't that be a sticky?

It's fixed now, sitting in the garage, awaiting instruction.
The diagnosis: I'm a retard because I don't know how to mount Ducati wheels.
The solution: When you mount a wheel on the S4Rs, you put the wheel on, hand tighten the nut and wiggle. If the nut feels tight and the wheel feels loose, rotate the wheel around one more pin. Repeat.
Apparently this was an issue on the 916?? I don't get it Ducati, why would you let me do this to myself! You must protect me from... me!
2 hours of labor + 4x $25 for the pins = $300 +change with tax.
God save me.
I wonder if this is an issue w/ the SBK hubs as well?

I'm almost certain it could be. It was an issue on the 916, and the 848 is similar design from what I've heard (I've never taken one apart myself).
Even bigger! ...on the 1098 SBK with the forged wheels: There are four holes for the pins to mate with on the wheel hubs. AND four kidney-bean shaped slots on the wheel where the pin COULD go. If you land on the slot instead of a hole everything will still bolt upstraight/true.
Damage will result.
Are the base/cast/848 wheels that way? I don't know. ???
Even on your car, it is common practice to spin the nut(s) down hand tight, give the wheel a spin to make sure spins "true", then torque.
At least you'll never do that again! [thumbsup]
;D
Good to know. I personally haven't removed my wheels, but Randy at the warehome did when he did my tire swap. I'm sure he it back on correct, I probably wouldn't have.

Yeah, probably not. Another Ducati lesson learned. Apparently I got lucky the first time.
tight wheels are overrated anyway 8) and let's hear it for DSS!! even i can't make the beast with two backs it up! (and that's saying something)

What was the two hours labor for? Did they have to disassemble the hub for inspection and repair? You got lucky on only damaging the cheap pins. I was afraid you messed up your hub and even the wheel. Glad you're back on the road again!
Changed rear tire last night. Another hub pin is cracked after only 2500 miles. So much for lining up "pin 1." If the dealer can't do it then how can I be expected to? More likely there is something wrong with my hub and the "pin 1" thing is a line of bull crap on this bike. >:(
In any case, screw it. I'm going to AR anyway. [moto]
hmm... "pin 1"? i didn't follow any such thing when i had my wheel off for the last tire change. everything has seemed fine so far though.

On the S4Rs, there is no such thing as "Pin 1." However, that doesn't stop Ducati certified technicians from holding to that belief. Can we please keep faith out of engineering?
This needs to be on the That's BS thread. Sorry Patrick, how aggravating. I've ridden with you so I know it's nothing you are doing while riding. No way. And if AMS put it all back together this last time then what does that say? Bad hub/pins? Sounds like if Bayliss' crew had put it back together then it still would have happened. What's up with this pin #1 crap? Hope you get it replaced before Arkansas. [thumbsup] Does the wheel hub with the holes for the pins look OK? In other words are the holes wiggled out any? Is the rear wheel retaining nut some way, some how coming loose? Nah, that would be stupid, you'd feel the squirreliness immediately. Forget that.
Puzzling evidence. :P

The nut was still on tight this time, and there wasn't any wiggle room when it was all torqued down.
I'm still going to AR this weekend to see how much more damage I can do. ;)
