Slowly loosen the nut on the spring’s outer cover. When the tension on the nut is loosened the spring will unwind, (while still under the metal cover). Once the tension of the spring is released you can remove the spring cover completely. Then you will be able to remove the 3 prong handle from the other side. It’s been a while since I did it but I think the spindle will then drop straight down.

Caution: the spring is a coil spring and if you just pull off the cover it could unwind rapidly and cut your hand.
