LINEAR VIBRATION CONTROL
TESTING AND ADJUSTING
Figure 2 shows the assembly of a 5N39, 5N40, 5N41, or
5N42 generator to a 3408 PC-TA Engine having a
7N6395 flywheel assembly. Note that the fan of these
later generators has a long pilot diameter fitted into the
flywheel pilot bore. Balance weights are added to the
flywheel when driving single-bearing generators.
FIGURE 2
Necessary dimensions for coupling other manufacturers'
generators are given in Figure 3. The required balance
weight assembly for various generator rotors is in Chart
G. Dimensions for local fabrication of the weights are
Figure 5. Weights are assembled on the outer diameter
of the flywheel directly opposite the flywheel balance
weight (pressed-in dowel). See Figures 1 and 4.
