Measure the axial distance from the surface on the generator adapter
to the outside surface on the drive disc coupling plates (dimension Y
in Figure 12). This dimension is recorded on the Factory Recorded
Dimensions sheet, which was packaged with the generator. If the
dimensions do not match, move the rotor axially relative to the stator
until the dimensions are equal.
Measure the axial distance from the machined surface on the engine
flywheel housing the bottom of the flywheel drive disc recess
(dimension G in Figure 13). Make sure the difference between
dimensions Y (of Figure 12) and G are less than 1/32" (0.794 mm). If
G is more than Y , install additional spacers between the drive discs and
the generator hub. If Y is more than G , remove spacers between the
drive discs and generator hub.

Install the generator to the engine. Make sure the drive discs seat in
the recess of the flywheel housing. Secure the generator to the engine
(drive discs to flywheel, adapter to flywheel housing), and the base.
Use lock washers on all bolts. Torque the adapter and drive discs in a
crisscross pattern to the values in Table 5 and Table 6.
WARNING: Never grind the OD
of drive discs or attempt to drill out
the holes. If the dive discs do not fit
properly, use different discs or a different
flywheel. The number and thickness of
the drive discs are specified for torque
requirements. Do not remove drive
discs to compensate for spacing. Drive
discs modifications may result in drive
disc failure and debris ejected from the
generator.
