IMPORTANT
The spindle has two flattened sides, as shown in
the figure on the left. These sides are provided
to enable you to properly lock the spindle (with
a wrench, etc.) when fastening or loosening the
gland nut. Do not apply force upon them for any
other purposes. Any excess force can deform
the sides because their walls are thin. Do NOT
apply such force especially when the gland nut
has been removed. When removing the spindle,
ALWAYS remove the jam nut first and then pull
the spindle out by hand.
