Pella casement window doesn't snug

The casement windows in my house are nearly 50 years old and one of them has shifted slightly in the frame toward the hinge side so that the snugging hooks don't catch. These windows predate the adjustment nut on the arm mechanism and everything is concealed inside the wood frame. It appears that if the sash could be shifted about 1/8" toward the hooks they would catch. Short of screwing the sash to the frame (which I've done temporarily to seal it better) does anyone have a solution.

Push the sash closed from the outside then latch it. Or buy yourself a suction cup with a handle to put on the glass and use from the inside as needed. Harbor Freight has them for $8.

I have no problem pushing the window shut from the outside and cranking as tight as possible, but that still allows a 1/16" air gap along the snugging side. Without snugging it tight, it doesn't seal. What appears to be occurring is the sash deviates just far enough away from those snugging hooks that they displace off the end to the clips on the sash that they're supposed to grab. Those attachment clips mounted on the sash are cast and can't be bent and remounting them appears to be rather tenuous. Is there some way to move the sash that 1/8" inch that it's displaced laterally? That's what that adjustment accomplishes in newer mechanisms.

No, if its loose you need to replace the gasket around the perimeter of the window. After 50 yrs I expect its lost any flexibility it once had.

If you wanted to experiment you could scuff up the metal and add a little jb weld to the outer edge of those sash mounted clips, so that they would be slightly thicker. Maybe the hook would pull it a bit tighter. Other than gasket replacement its my only idea.

Thanks. The gasket appears good and is pliable, it's just that the sash is offset that little bit. Checking others around the house it appears all of them require that extra compression from the snugging arm to seat firmly. I'm not sure about JB remedy. The problem is not in the diameter of the snug lug but in its length. I wish there were a way to access the hooks so they could be bent toward the sash a little more.

Well, I am a Pella installer, so if those suggestions don't help, I have nothing else to add.

I am talking about adding a bit of jb weld to the back side of the keeper on the sash, not the hook. And you don't bend the hook. Adding a little thickness to the keeper would cause the hook to pull the sash a little tighter when you lock it. You would obviously need to wait for the jb weld to get hard before you attempted to lock it.
