This is on a 900ie that's going into a 750ss track bike. Bought the motor used with unknown mileage. Everything looks *great* under the valve covers, and the clutch looks normal.
I just drained the oil out of this thing (it looked normal as well) and there was bad stuff stuck to the magnet on the drain plug. I expected to see some debris on it, but it was covered with what looks like half moon slivers of metal. Almost like when threads pull out of a tapped hole.
I know I've read about this before, but could find nothing with the search function.
Im heading off to take a picture now.
Help :'(

It sounds like it may be the oil galley plug backing out.
crank plug shavings are aluminum .......hmmm aluminum magnet? lol
probably one of three things.
1. normal gearbox wearing in. Is it a low mile motor?
2. ball bearing failure, a bearing is shedding metal. these usually do not look like thin shavings more like small flakes.
3. alternator nut is loose and washer behind starter clutch is being eaten.
happy hunting

Its on it's way out. Might as well install nitrous.

The drain plug? Not sure what you're referring to.

Again, mileage is unknown. The inside of this engine looks great so far btw.
I really don't think this is normal wear for anything. These slivers are magnetic, and really hard. I can't bend them with my hands.
Ill check the washer behind the starter clutch. Im pulling the flywheel and left side gears and taking them to a shop I got access to this Saturday for *extensive* lightening. [evil]

Soooo.. .
you're saying I should ditch the turbo?
Also, fwiw the oil screen was 99% clean when I pulled it. There were 2 flakes of material on it.
What happened to the pics?
Check out the crescents with a magnifying glass to see if the sharp edge is on the inside or outside, i.e. from a bolt or from a threaded hole. Then try and work out what the diameter is, that will narrow down your search a bit.
Buying an unknown history motor means a teardown and/or rebuild should be figgered into the deal

I don't know why these don't show up. The url goes right to the pics when I copy paste to the address bar :-\ No time to fix it now. . .

Fixed it for you.
You did? I just removed the [img] tags so just the links show up.
I still don't see them. . .
In first pic

looks like someone dropped a clip or 2 from inside shims that keeps them on the valves.
They usually wind up on magnet, no worries.
Funny, pics were visible a minute ago......

Put the damn image tags back in..... ;D [laugh]
When you link to a pic on a hosting site you can't use the url in the address bar.
You have to right click on the image and 'copy image location' and use that inside the tags.
Really? Ive used imageshack a lot, and I didn't do anything different this time than I normally would.
Ill put the tags back. . .
also, shim clips? I bagged all these chips and there's like 10 or 15 of them. They don't have round cross sections either so Im thinking they're not shim clips. . .

I opened the link, did copy image location, pasted here, highlighted the link, and clicked the img icon up over the smileys, clicked preview and nada. . .
You try it ;D

I had them working.... [roll] ;D
I'll fix it, but you have to promise to leave it alone. :P
I spoke to ducvet last night. He said chances are that's tranny stuff. If it's a low mileage motor that was ridden hard it's not unusual. If the bike was babied he said you could see that for a long time although not as much each time
Im planning to ignore it ;D
Ill leave the links alone. . .
Any input on cutting flywheels or gears? (see other thread in tech)
Also, if its from the trans, what specifically would be shedding metal like that? Ive never seen one apart so Im not familiar with the inner workings.

I guess everything...
not bearings so much as the engagement dogs and the slots in the mating gear.
Maybe he'll check the pics and offer his opinion.
Check the alternator cover bearing. Those go bad on late 90s models and it is the shaft making an oblong hold where the bearing sits -- and shaving off pieces of itself as it turns out of round.
Crank galley plug slivers will be non-ferrous, they are pieces of the CASE shaving off as the plug backs out. You will see them in the strainer, not the magnet.

Looked like it on the pic, but OK, 15.....
Could take a closeup on the chips, cleaned & away from the plug?
those look like a normal early ducati at the first or second oil change. I would venture a guess that you are looking at gear shavings from the gearbox. since you have no history on the motor (it is a 99 or newer for sure) I would assemble the bike and use an inexpensive "break in " oil. do another oil change in 1000 miles and you should see a cleaner magnet.
the crank plug on 900's are aluminum and they rub on the steel outer main bearing shell. any crank plug shavings would be aluminum from the crank plug. they would not be on your magnet anyway being aluminum. often the starter gear washer pieces will be larger and more flat.
good luck

Ducati gears are square cut and tend to loose the edges on teeth. They look like really small finger nail clippings. I got a rash of them on my first oil change after break in on both bikes (I started having fun ;D) . Might be previous owner never really thrashed at the transmission (good thing) or you've been messy at shifting (clunk!). I wouldn't worry to much about it until the next oil change. If they still show up in the same numbers and your sure you haven't been too hard on the trans then perhaps further investigation is warrented.

For the record I haven't run this engine yet or ridden the bike it's going In to. Since it's a track only bike you are ok to presume it will be ridden hard. Looks like it's probably fine from what you guys are saying.
I was planning to just run it anyway and see what happens ;D
I say ride it like a ducpainter.
what's the worst that could happen?
;)
Be sure to scope the screen..
Did that. It scoped out ok [thumbsup]
