Thanks for posting! Is the metal piece that the handle fits onto removeable? If it cannot be removed from the operator, you may need to replace the entire mechanism. Once you've determined this, I'll be able to better assist you.
Hello,
Thanks for the photos! Please do not remove the piece underneath. It is part of the operator and machine pressed into the base. If this is removed or dislodged, that would render the operator completely useless.
It appears you have a Roto hardware operator. So you'll need the 39-224 Fold-down Crank Handle. I am confident this should work for your repairs.
