You MUST remove the bottom plate BEFORE forcing of the wheel or you WILL tare it apart as there is a lug on the bottom plate that holds the wheel in place ( wish I had known this before I damaged mine)

also do not lose the very small spring that is under the wheel (I DID )

When you have removed the wheel please be carfull NOT to lose the verry small spring from a black plastic part in the center of the board, I DID

I agree with the other notes please see step 3 BEFORE 1&2
