500 spiral balance

A quick learner from coupeville says:
We have the series 500 spiral balance and are unsuccessfully trying to remove the bottom window. But we have removed the spiral balances and cleaned them up since they had a lot of dirt in them. What do you use to lubricate those?

Thanks for contacting us. I'm afraid some non-tilt windows are designed in such a way that it's not possible to remove the sash; at least, not possible without tearing the whole window out of the house. You may not be able to remove your sash, unfortunately.

As for lubricating spiral balances, we recommend white grease on the spiral itself.
A quick learner from coupeville says:
Thanks Tom. Yes, no removing of the sash. Now to figure how to reconnect the spiral balances to the hooks at the bottom of the window inside the frame. Any ideas since we cannot remove the window. We will use the white grease.

Sure, there's a method we use that seems to work well enough. It can be a bit of a project, but we think it's the best way to go.

With someone helping you, you will need to drop the new balance in from the top of the sash, screw it in at the top, then let the spiral drop down. You will then raise the sash and, while someone holds the sash in the open position, spin the spiral up to the bottom of the sash. Finally, with our 75-004 tool, give the balance about three turns to charge it and lock it to the end into the sash clip.

Let me know if you have any more questions.
