a.
Side
Brace Links. To detennine
the
serviceability
of
these parts requires
the
inspection
of
the
threads for wear, by
detennining the pitch diameter
of
the threads. There are two methods as follows:
1.
Thread
Ring Gauge Method (See Figure 6-Sc). The following is the suggested method for
checking thread wear:
(a) Procure
standard thread ring gauges for the thread sizes specified in Figure 6-Sc.
(2) Using the instructions provided by the thread ring
gauge
manufacturer, check thread
wear and determine pitch diameter. Figure
6-Sc shows a typical three-step process.
2. Three Wire Method.
(a) See U.S. Department
of
Commerce Screw
Thread
Standard H-2S Handbook or any good
machinist's handbook.
(b) Follow the procedure given and calculate the pitch diameter based on wire size used.
3.
If
the link is worn in excess
of
the tolerances given in Figure 6-Sc, it must be replaced.
b.
Rod
End Bearings.
1. This check requires the use
of
a NO-GO thread plug gauge (refer to table included
in
Figure
6-8b for
the
specific size gauge to use). This gauge can be purchased from any good tool supplier.
2.
If
the NO-GO gauge can be screwed into the bearing, the bearing is worn larger than the
tolerances given in the table with Figure
6-Sb, and must
be
replaced.
NOTE
The
NO-GO gauge should not fit a serviceable bearing.
