Windows have dual coil balance springs on each side of window.
Upper coil spring is labeled 440 and lower coil spring is labeled 540
Width of spring is 1/2 inch
Weight of window is 23.4 pounds
Springs are 25 years old.
All other parts work properly, tilt window shoe locks etc.
Springs are held to shoe locks by part
33-073 screw.
Which coil springs do I need to order?
Concern is the 440 S190 and 540 S190 springs appear to be 1 inch wide versus the slot just fitting a 1/2 inch wide spring.
