Found this on the magnet part of my sump plug

Just dropped the oil on my 1198S and found this on my sump plug!



Any ideas?

I have sent the photo to the bike shop and I'll ring them in the morning.

The bike is still under warranty so any work should be covered.

DON'T start the bike! Its a valve shim collet!!!! Might have been dropped during assembly but don't take the chance. Catastophe will result if its from one in the head!!! Trailer it to the shop or make them pick the bike up.

If the bike was running fine before the oil change, then it is probably from assembly. BUT to be on the safe side, do what eltwin suggests!

Had a look at the spare parts manual and I think you are spot on. Will take your advice.

Thanks

I have found a few of these in Ducati sumps over the years. You don't mention the mileage, or whether your valves have been adjusted, but it's definitely a valve retaining collet.
N.B. Anyone adjusting valve clearances should insert a piece of rubber hose into the oil drain holes by the exhaust valves, particularly on the rear head, to prevent this happening.

Bike was serviced at 12,000kms and has now just moved past 15,000kms. I change the oil and oil filter every 3,000kms.

Bike has just been picked up for transfer to bike shop.

As they say Quality Doesn't Cost It Pays!

Heads stripped off and everything is where it should be. From my understanding the only way an object from the head could get into the sump would be via the oil filter so sort of impossible (I'm told).

The aftermarket TPO sump plug which I recently installed with its bigger magnet might have picked it up when the OEM one didn't.

..........
Nigh on impossible for a collet to escape from it's keepsake without some prior mishap either. It would have to show some signs of damage if not a work polished contact area. I'm guessing yours had neither and was a whoopsie at build time.

A big sigh of relief hey ?

Pleased to hear all is well. A bit of an inconvenience but better that than the catastrophe Smarty suffered! His engine was all but destroyed. Enjoy the ride when you have it back.


By the way, they are giving you BS telling you that it has to pass through the oil filter to get into the sump. Oil is taken from the sump, then pumped through the filter before entering the internal bearing lubrication passages for the crank and cam bearings etc. Brett is correct that it's almost impossible for a collet to escape in normal service but my concern was if one got dropped during your shim check and not noticed, resulting in reassembly with only one of the collets installed rather than the pair. They will run with just one collet.... but not for long!

Pat 1098 is spot on, collets can be dropped and will fall into the oil return hole leading back to the sump. I normally use a rag to prevent this but will now adopt his idea of the rubber tube, Cheers Pat.

No not true.A collet can easily get to the sump from the head via the oil drain/return galleries from the head.Same way the oil returns from the head to the sump.
My guess is that it was dropped by the mechanic on the last valve adjustment and he obviously wasn't going to strip the engine to find it so just grabbed another new one one fitted that,or its from the factory original build and has eventually dislodged and come out with an oil change.
No garantee a bigger magnet will capture stuff like this either.If it finds a nice cosy little spot to live in the engine and is trapped there the magnet wont necessarily drag it over and capture it.Mag pickup are primarily for collecting ferris material held in suspension in the oil as it passes over the magnet.
