Can a broken rotor enter the motor???

I get a call from my mechanic today.

A bit of background.

I wrecked my bike and brushed into another bike.

The other bikes foot peg hit my rotor cover, it tore the cover and it broke the rotor.

My mechanic says that the gear behind the rotor broke as well.

He says he recovered 7 teeth but 21 are missing still.

He wants to pull the pan to see if any ended up inside the motor.

I do not have the bike here and he is far away so I cant get right out to see it soon.

How could that be possible. It is my thoughts that the rotor is sealed from the inside of the motor. There is no way IMO that the teeth could have gotten into the motor.

I know a few of you guys have taken apart their motors already.

So what is the deal?? Is it possible that the teeth got into the motor??

Please help!! Thanks ya'll!!!

ya ya ya...

I can't help, and I'm an ignoramoose, so if youre not talking about the brake rotor, what is it then, if you don't mind me asking.

The timing rotor isn't sealed off from the rest of the motor. I haven't had the 10R motor apart, but I'm pretty sure the timing chain is right behind the timing rotor. The oil from the head drains down this channel and into the sump. Also, there is a crank main bearing behind the rotor, and its got its oil supply to drain as well.

Since the motor was spinning when the footpeg entered, I'd assume that it sheared off all the teeth right quick like your mechanic is suggesting.

Of course, if you're talking about a brake rotor, forget anything I said!

of course I mean the timing rotor.

yes he says the teeth sheared off and are are missing.

He says he thinks they drained into the motor.

Damn this is turning out worse than I thought!

If I have the pan pulled off do you think I will be able to recover all the missing metal?

ya ya ya...

I would think that you could drop the pan and find most if not all the teeth. The oil pickup screen should have kept the major bits out. The acid test would be to remove the oil pump rotors and see if any trash went through them. If any did, you're looking at a complete teardown to be safe. I think you can get the oil pump rotors out from the clutch pack area without a total disassembly but not sure.
