New hinges and cranks for casement windows

I have both LH and RH opening windows that need complete hardware replacement. (Both open in opposite directions.)

Looking for new opener hinges as well as the crank mechanism and the handle for each.

One of the photos has approximate dimensions.

I haven't disassembled it and taken pictures yet. Let me know if that is necessary.

I would also like to know about (and purchase if necessary) any unique kinds of tools required, along with some recommended lubricant.

I really don't want to pay for window replacement so you guys are my last hope!
