    Left crank grommet pops out of hole

    Is this grommet solely a dust seal? It should fit in the ring slot around the crank arm and within the bottom bracket.

    I tried pushing it back into place, but it just pops/slides loose again--without the cranks spinning. If they spin, it comes right out.

    How urgently do I need to pull the crank arm to address this? Rather, what is causing it?
    Running season is in full bloom but I have the itch to ride cross.

    I'm having trouble understanding where this is. Can you post a pic or find a similar one online?

    Neither of those first two, from what I can tell. It's these exactly:

    Pull crank arm, unscrew lock ring , remove cup there will be a groove in the cup for the dust shield to go into. (maybe)
    see if you can fit that ring back in there again.

    that far in , you might as well do the rest.. overhaul the BB .. clean fresh grease and new balls...

    [ no need to remove other cup just clean , grease and drop bearings into grease.]

    That's seal-ring for the bottom-bracket. May have been installed backwards.
