To get the spring clip off (aptly names the jesus clip in my work shop as I usually say "Jesus where did that fly off to") can be gently removed by levering begind them with a flathead screwdriver from several angles, just be careful and try to watch where it flies off to. If you happen to break them they are fairly cheap at your local mower shop.
They do bend a bit when removed but once pushed back on they generally take shape again.
