When screwing in the diaphragms [15] on the shaft
[16], the holes in the diaphragms must align with the
holes in the centre block [12]. Sometimes it is
necessary to turn the diaphragm back a little bit in
order to align the holes.
When putting in the pin screws [14] take extra care not
to damage the diaphragms [15] with the pin screw
thread.
