have only two cover screws; the cover screw shown near the
frame knob isn't always used.
Now lift the cover slightly and slide out the old damping arm
(from right to left in Fig. D89). The end of the flat spring,
Fig. D89, hooks over two lugs under the cover. You can't see
the lugs with the cover installed. But you can feel when the
flat spring is free.
Remove any sections of the old plastic damping arm. Then
install the flat spring into the new damping arm as shown in
Fig. D90. The flat spring passes through the slot indicated
by the arrow in Fig. D90. The curve in the flat spring then
fits around a section at the back of the damping arm. Fig.
D91 shows the spring/roller installed on the new damping
arm.
Replacing the damping arm in the mechanism requires a little
feel to find the hidden lugs. If we had removed the cover,
you could see the lugs for the flat spring, Fig. D92. In Fig.
D92, the holes in the flat spring are seated over the lugs.
Even though you can't see the lugs with the cover in place,
you can feel when the flat spring is properly hooked. Slide
the flat spring through the cover slot as indicated by the
arrow in Fig. D91. Shift the position of the damping arm,
until you can feel the holes in the flat spring clipping over
the two hidden lugs. Once you can feel that the flat spring is
connected, tighten the cover screw you loosened. Then
replace the other screw(s).
Finally turn over the mechanism and locate the latching
mechanism for the damping arm, Fig. D94. There are two
different types—one using a torsion-type spring, Fig. D94,
and one using a coil spring, Fig. D96. If you have the
torsion-type spring, the long end of the spring came loose
when the damping arm broke or when you replaced the
damping arm.

how the flat spring seats over a pair of posts.
