I have a question

I know that this is a dumb question but there’s space between the frame and the bearing cap in my kh
but I bought it used so I don’t have the manual.
Is it supposed to to that? :thinking:
Because I’m afraid that sand might go in the bearings and ruin the hub.

how big is the gap? millimeters, centimeters, inches etc…

that’s for the schlumpf hub i think.

pics please?
