Bluhduh Oil Change OUCH!

Doing an oil change on my '04 Adventure and found 4 roller bearings (2.0 X 4.5mm) and a partially mangled bearing cage attached to my magnetic drain plug...looks like the some of the cage pieces found their way to the filter screen above the check valve screen in the oil tank, and some bits landed on the flat screen below the clutch cover.
Any ideas where those puppies came from?
Bike sounds fine before and after the oil change, shifts like normal, but a touch cautious about driving it until I can locate where those pieces 'fell' from...
Looking through parts fiche and not seeing it...anyone want to chime in?

Riding it like that is asking for trouble.

Looking at the schematic, there is no way it can get from the engine to the oil tank, there is a filter screen before the scavenger pump and then there is the pumps itself. Cannot see how the bits could get through there to the oil tank.

Pictures of the bits would help to try and id the bearing, only bearing that springs to mind is the top cam gear bearing, I suppose if that had collapsed that could explain the bits if the sump, but not the oil tank.

Sorry can't help further.

The owner of this site, Baldy, also owns Smugmug. A lot of folks on this site think it's nice way to kick him a few bucks by paying Smugmug for image hosting, although you can use other image hosting sites.

Sorry about your troubles; I probably won't be much help, but I'm hoping the best for you!

How's your shifting? I can't remember for sure, and I'm really grasping at straws here, but I'd wonder about the shift drum bearings if it were me. I thought they were both ball bearings (schematic shows both being balls), but I could be wrong.

None of the other bearings, especially any of the "roller" or "needle" bearings are 4.5mm wide. Crank is supported by plain bearings, the balance shaft (or combination shaft, or whatever the hell KTM calls it) is supported by ball bearings, as are 3 of the 4 trans shaft bearings, outboard countershaft is a roller bearing.

The only other thing I'd wonder about is the bearings the shift shaft runs in, but the schematic calls for a 12mm wide needle bearing.

Gloom, Dispair . . . .

How I'd feel if that happened to me:

With a twin like we have.....there is usually no harm riding it until you find a piston stuck to the drain plug.

Just to clarify: you found these in the OIL TANK? or in the ENGINE? drain plug magnet.

I assume the engine drain plug, because there is NO WAY these items can get into the oil tank unless they fell out of an oil bottle when you filled it.

KTM has had some problems with the bearing on the transmission main shaft right behind the clutch on other models. Easy to check. Pull the inspection cover and wiggle the clutch up/down, front/back. If you get more than a few thou... start saving your money.

I have an engine in pieces, the only small rollers I remember in the motor are the gear shaft ones.

When this happens (notice the large chunk missing from the one on the right)on a 6 month 25k mile odyssey:


It's followed by this:






Notice the size of the bearing lands on the shift drum, hence my guess that that's the bearing that let go. If it's not the shift drum bearings, I'd go with the shift shaft.



If you look close, you can see one of the shift shaft needle bearings.

As for riding it like that, imagine what could happen if one of those rollers found it's way into the scavenge oil pump, stopping the rotors and shearing the drive pin in there. No oil pressure usually means a quick death for the plain bearings that support the crank. Or how about what would happen if it found it's way into the trans, between gears? It could lock the trans, causing a sever and drastic loss of control as the back wheel locks up at speed.

Park it until you fix it. Sorry, but it looks like you're splitting cases. Look at the bright side though- if I did it in a redneck's (oops-I mean inmate's) garage in Alabama (Hi Scott! ), how hard can it be?
