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?

Good morning, and thank you for posting on the discussion board! The damage in your photos is the result of a stripped out worm gear. This can happen if the handle is over torqued one way or the other during operation.

This can't be repaired, unfortunately, so you will need an all new operator. We have a ton of different options that might replace this depending on the design of the rest of the mechanism, so I'll need photos of the entire operator removed before we can make a suggestion.

For now, take a look at our 39-031 and 39-032, as well as the 39-155 and 39-156. These are strong possibilities but far from the only options. Additional photos will allow us to narrow things down further.

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'm sorry to say that replacing the entire operator is necessary when the worm gear strips out. These are machine pressed at the factory, so it's not possible to repair on-site.

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

Hello Annlouise. Yes, as stated above you will have to replace the complete operator if the worn gear has popped out. There is no other solution, unfortunately.

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?

The operator in the photo above only shows a portion of the assembly, so I cannot make a recommendation based on this picture alone. You will need to remove the operator entirely and show us a photo of it without obstruction so that we can find you a good match.

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!

Hey there, maybe I can help. In order to access the screws you will need to remove the wooden sill trim first. You should be able to pry it up, but take care not to crack the wood cover. These are normally held in with small trim nails that can be reused when you're done.
