cutter base (4) as shown in Figure 184.
a.
If a fire ring groove (3) is visible, check
the existing fire ring groove depth
dimension with depth gauge J 26948.
The difference between 0.008 inch and
the actual remaining depth of fire ring
groove is the amount to cut. Insert two
appropriate thickness gauges (2)
between the cutter head (1) and base
(4).
b.
If a fire ring groove (3) is not visible,
insert two 0.008-inch thickness gauges
(2) between the cutter head (1) and
base (4).
5. Adjust the cutter head J 37719 until it
bottoms out on the deck surface of the
existing fire ring groove. Tighten the cutter
head in this position and remove the two
thickness gauges.
