Are you referring to the flywheel? -looks your pilot bearing came apart and needs replacing. Not a big deal but will require pulling the transmission or what ever the engine is connected to.

Or are you referring to the front timing gears? -dunno

Hope that helps,

Sorry your wording is off a little, do not understand the "wheels" bit.
Those are needle bearings. What was the problem with the starter motor?
