Anderson Crank outs.

They can't be repaired because the previous owner threw away part of them.

There is a push in bushing on the end of the shaft.

I "repaired" two of similar ones (wheren't for Andersen's) with epoxy. One failed right away. Don't know about the other one.

In this case I the HO told we what happened. Kids trying to force the windows without opening the latches.

Might have been what happened in your case.

THAT IS EXACTLY RIGHT

THAT IS THE MOST COMMON REASON FOR CASEMENT HARDWARE TO FAIL IS DUE TO HOMEOWNERS NOT JUST KIDS TRYING TO OPEN THE WINDOWS WITHOUT UNLOCKING THEM FIRST. ALSO THE HARDWARE MUST BE LUBRICATED PERIODICALLY ALSO. AND THE BOTTOM OF THE WINDOW SILL CLEANED. IF THE WINDOW SILL IS DIRTY THAT CAUSES FRICTION ON THE HARDWARE WHICH WILL CAUSE THE HARDWARE TO FAIL SOONER. BUT EVEN THE BEST HARDWARE WILL FAIL EVENTUALLY DEPENDING ON AMOUNT OF USE. NOT ANDERSENS FAULT IN THIS CASE.

I have found my own solution.

I have assembled the cranks as original and then used a punch to stake the surface around the bushing and create a tight fit which is better then new.

In case anyone finds this: I had the same thing. I don't get Billhart's answer, but carbonater55 is on the track I found.

The screw turns inside the tube (worm screw inside the shaft?) until one day (I think while you're closing the window) it pops out. When you remove the plastic cover, nothing looks broken inside. I believe the near (inside of the house) end of the shaft is supposed to have a smaller collar (bushing?) to keep the screw in, but the screw eventually wears it away and pops out.

So yes, I got a hammer and a nail punch, punched the screw back into the shaft, then punched the end of the shaft inward to jerry-rig a collar. That (and some lublication, and going easy when I close the windows) should buy me a year or two, but then I expect I'll have to buy a bunch of new cranks.

That isn't an Andersen operator.

BV001448 is right. I just tried it on a popped out crank shaft in my casement window. Here is a tip to make the job much easier: Once you have the shaft back into its supposed position, instead of using a nail punch, which has a small head, hard to aim & easy to miss the top part of the shaft holding ring, get a cold chisel & use that instead. Hammer the chisel around the top part of the shaft holding ring, give them a few hard hits & leave obvious dent marks. It worked for me. A new replacement hardware costs $50+ here in HomeDepot Canada & I've purchased at least 3 in the past few years. This sure saves time & $.

I reseated the screw shaft with a deep well socket first. It seated well and did not pop out. I hen dented the casing to further secure the screw shaft. Seems to work well

Attached is a photo of the part for my bay window cranks. The windows crank out but cannot retract. The crank screw appears to be striped. Where can I purchase replacements.

Hi,
New at this, but have had the Andersen windows for over 20 years. The case is cracked so I am going to replace the case.
The crack works when opening the window, but will not work when I try to close it, just keeps turning. Do I need to replace the crank (handle) or anything else?

Sorry, typo above the Crank.

Andersen sells to parts. These cranks fail often, and if you do not keep the track super clean and lubricated, you will learn to hate them.

Also, I think that leaving the window partially open strains the mechanism due to the wind hitting the window pane and continually putting a stress on the worm gear retaining system. After years of this, it is bound to wear out.

It was a little difficult to grasp the instructions but after I quit looking at the pin end of the worm gear and focused on the bushing just under the plastic shroud it made sense. The housing material is quite soft and I tapped in many points with a medium screwdriver and it worked great. If it happens again I'll just repeat the process! Thanks to all!!
