Removal
To relieve the compression of the springs in
the actuator, proceed as follows:
1. Unthread and remove the short nuts and
bolts (including the washers) on the dia-
phragm cases.
2. Loosen the long clamping nuts and bolts
on the diaphragm cases evenly in a
crisscross pattern to gradually relieve the
spring compression. Hold the bolt head
stationary with a suitable tool and apply
the torque to the nuts.
