Window Hardware | 26 Mar 2012

If your window crank is not working, you may feel that you are at a loss because you do not know how to replace casement window crank operators. However, what you should remember is that this is not a very hard job to do. In most cases, you can replace this part of the window in about an hour if you have some idea of what you are doing. Here we will talk about how to do this so that you can have your window functioning properly in no time.

Making Sure That You Are On the Right Track

Before you start getting all the materials together, one thing you should do is make sure that you are doing the right thing by replacing the casement window crank operators. First of all, does the window shut and open successfully? If it does not shut all the way, then you may have another issue that you need to deal with. This is an important thing to figure out before you start to work with the casement window crank operators.

Replacing the Mechanism

If the handle of the crank just spins as you turn it, then chances are that the gears are stripped inside the mechanism. You will need to replace it, and this can be rather simple. The hard part is actually finding the crank that you are going to use. It is not as simple as buying a new screen or window frame. Instead, you may have to spend quite some time searching online for the one that will fit.

Once you find the new mechanism for your casement window crank operators, you should spend a few minutes making sure that it looks the exact same as your old one. This will help assure that you have an easy time installing it. The only time you have to replace entire casement window crank operators is when you have:

  • Worn out gears
  • Missing gears
  • Worn out crank arms
  • Missing or broken splines on the crank stud

Removing the Old Parts

The first step to replace casement window crank operators is to remove the old one. This can be done rather simply. The best thing you can do is look for pictures online of your specific situation if you feel confused. Basically, you are going to remove the screen and open your window.

Then, you will remove the casing that covers your casement window crank operators. You will either have to remove some screws, or use a putty knife to pry off the material if it is stapled or nailed on.

Adding the New Parts

Once you get your casement window crank operator out, you can shut the window for the time being while you order the new one and make sure they match. Once you are sure that they match, you can screw the new one into place quite easily by following the instructions.

You will see that replacing casement window crank operators is not as hard as you would think. The best thing to do if you are too confused is to have a friend with you or find some pictures online. Take your time and be sure to keep track of all the screws so that you can have a successful time replacing this broken part.
