thickness was 1/8 inch (3.17 mm). The internal wear plates
(Inside the planetary stages) can stand about 3/64 inch
(2.38 mm) wear before the gear teeth will start to cut into
the wear plates. The wear plate in Figure 5J-16 can stand
about 1/8 inch (3.17 mm) wear. Note that wear on the
interstage surfaces should be even across the entire surfaces,
and should show up as a concentric circle within the I.D. of
the wear plate.
