Took the bike in for its 12k service earlier this week and to get the oil leak resolved. As suspected it was the drive shaft oil seal thats causing the issues. Motor didnt have to come out of the bike to get to the seal, but it was quite involved. Anyway here I was expecting to be back on the road after a couple of days only to receive a call from the dealership to say it will be out of action as more parts are required. What they said was "the clutch basket posts were cracked and ready to break off", well I must say this came as a surprise as the bikes been running fine. (Saying that, I must admit early on in the piece I did have issues changing from 2nd to 3rd where it seemed to be stuck in gear , resulting in me having to try a few times to change gear, but over the past 9000k's it only happened on the rare occasion so I assumed it was just the gear box freeing up). Now it looks like the bike could be off the road for a while, just as well I've still got the "old sport" which is coming on to 278k's ....might end up making it to 300k's yet.

V100 clutch basket failure
- Thread starter Tonym
- Start date
Sounds like the cause for the service bulletin for the clutch o-ring?
I had mine finally exchanged by the shop a week ago.
“Last minute” they said, could work a while still if I would’ve been lucky.
This o-ring seal had deteriorated to the degree that the seal began to be disintegrated and would soon leak hydraulic fluid into the engine, and lose clutch function.
If it was hydraulic fluid or brake fluid in the clutch system I don’t remember, but the o-ring material wasn’t made for that specific fluid.
They showed me a photo of the o-ring which still was attached inside the clutch cover, and the rubber material sort of leaked out from the position(!).
Didn’t ask for the picture at the time, but the reason for the service bulletin was clear!
Anyhow, the symptom would be a clutch failure.

I am having a hard time reconciling exactly what are the "Clutch Basket Posts". There is a part called the Clutch Drum. On a typical clutch, there would be hollow posts which go trough the center of the springs and then accept the bolts which pass through the pressure plate. The V100 clutch is a good bit more complicated but still, the only posts I can picture would be three posts inside the Clutch Drum which accept bolts that pass through a Disc and Clutch hub. There would be no torque passing through these posts, not sure how they would crack unless,,,,, something like 50 years ago (you read that correctly) 12 year old me was attempting to put new clutch plates in my Yamaha MX100. There were six clutch springs and I managed to break off two of the posts. The bolts were actually screws with a cross head. Of course, I used a standard Philips screw driver and stripped out all six. I don't know where I learned how to use a hand impact screw driver but, in any case, if a hand tool doesn't work, try a hand tool with a hammer! It worked on four and broke the post off on two others. As luck would have it, they were opposite of each other. I had enough mechanical sense to know that being down two clutch springs meant that the lost force would need to be made up, somehow. It never occurred to me to replace the hub. It was held on by a big nut and no way was I going to get that off with a pair of Channel Lock pliers, heck, I don't think the Vice Grips would have worked either. I found some conveniently sized washers and put a couple under the spring retainers of the four remaining springs. Rode it like that for at least another six years. I digress, back to your V100.
I wonder how these posts broke off? I am inclined to think it happened during the disassembly process rather than the you dumping the clutch process.
Hi Racer242,
sounds like your on the money. Got some pic's from the dealer this morning. To quote them:-
"We've sent a case through to Guzzi, just waiting for a response. Bit of a strange one, we haven't come across this issue before but we're looking into it."
Believe replacement part is in stock with importer so hopefully I wont be off the road for too long

Imagine backing out the bolt that goes in to those posts? You better use two hands on the socket wrench, one to hold the head end in a centered position over the bolt and the other hand to provide the torque. It would be all too easy to break those off instead of turning the bolts. In any case, I can't see how the clutch would have been functional if even one of those was broken.
