Check the generator coupling’s radial and face runout by mounting
a dial indicator to the generator adapter as shown in Figure 5. The
maximum radial and face runout on the coupling must not exceed
0.003" (0.0762 mm).
NOTE: Mounting of the indicators must
allow complete rotation of the prime
mover.
Use dial indicators that are rigid so
indicator sag won’t be a factor. Using the
shortest offset distance of the indicator
bracket will reduce the effects of indicator
droop or sag.
During alignment, you may also need to
compensate for engine expansion due to
heating. Generator expansion is generally
not considered a factor.
If the genset is moved to a different
location, check alignment before startup.
WARNING: Do not pry on the
generator fan blades. Blades can weaken
which could result in serious injury or
death from flying debris.
NOTE: Generators equipped with sleeve
oil bearings must have oil added to
the bearing prior to rotation. Failure to
comply will result in bearing damage. See
the bearing manual.

Check the generator adapter’s radial and face runout by mounting a
dial indicator on the generator shaft or coupling as shown in Figure 4.
The maximum radial and face runout on the generator adaptor must not
exceed 0.010" (0.254 mm).
