BiltBest window crank parts 14 45054 & 16 45054

I have a situation the same on two of the windows in the house and I can't seem to locate the part/parts that I may need. on the underside on one of the cranks the numbers found are 14 45054 the other is 16 45054. When I was cranking the windows closed, these parts detatched from the window. Im not sure if the crank is the part needing be replaced or the casement? Can anyone please help? The name "BiltBest" is on the crank operator cover.

I have a similar problem in that several my windows the worm gear (i don't know what you call it) has come loose and I am not able to shut windows. Do I have to replace the entire window crank or is there a way to fix or replace just the gear??

I have the same problem as Tom . My crank part # is 45012. Do I need to replace the whole mechanism too ? Thank You , Annlouise

I have the same biltbest window cranks as pictured. The window will crank open, but the handle falls off when I try to crank it closed. What parts will I need to replace?

Hello, From the above posts, I can tell that I need the 39-031 Operator, but here is my question: How do I remove the old and install the new without removing the wood strip above the crank operator? Or is that just part of the process? Thank you!
