Beneath the diaphragm rotor, there are 10 diaphragm
leaves positioned within the circular recess of the metal
diaphragm stator. See

Figure 85 – Diaphragm leaves in the metal stator
Remove the 10 diaphragm leaves from the metal
diaphragm stator by carefully lifting the individual
leaves such that the pivot pins come free of the pivot
holes in the stator. See

Reassemble the Field Diaphragm Assembly (Old Style)
Exercise caution when handling the diaphragm leaves
during reassembly, as any oil or contamination on the
leaves can impair proper operation of the iris
mechanism. When reinstalling the diaphragm leaves
into the metal diaphragm stator, it is important that the
pivot pin at the end of the leaves with relief notches (if
present) are placed into the holes in the metal
diaphragm stator (See

on the opposite ends of the leaves. These recesses
provide clearance to prevent the leaves from interfering
with adjacent leaves. Note that the leaves in some
