Window balance for Wind shield window

Hello! We can replace this balance, but it will have to be a special order because of the shoe you're using. It looks like you have an S751-31 balance, but with the bottom shoe it usually comes with swapped out for our 15-197. Does that look right to you?

If so, please let me know how many of these you need. I will then email you an order link and price quote for the requested quantity. 

You got it, I'll shoot that over right now. Thank you for considering us and please let me know if you have any other questions!

These ribbed balances are made to slide down from the top of the vinyl track. To remove your vinyl tracks, you would first remove the top and bottom sashes from the window. Then you would pull on the vinyl track from the top and carefully move down to release it from the window frame. We have a video that should help with this process, which you can see at the end of this post. 

It sounds like you have very heavy sashes, which is why the springs are strong and hard to pull. I've spoken to service technicians who use a pair of needle nose locking pliers and a vise. You want to place the balance in the vise and pull the shoe about 6" from the balance channel and lock the cord so that the shoe has play. Then, slide the shoe in the track from the top with the cord leg away from you and the metal fork pointed up so that it will slide in the track. Follow it with the ribbed balance and the "S" hook. Hook the "S" to the top of the vinyl track. Place a screw driver on the metal fork to go down and lock in the track. Now you can remove the locking pliers.

Let me know if you have any questions. Here's the video:
