Mount a dial indicator on the flywheel coupling to the face of the
generator half coupling for angular alignment as shown in Figure 7.
Align the engine by rotating the prime mover in 90
° incre ments and
measuring TIR (total indicator runout). Tighten the generator to the
base before taking each set of readings. Raise or lower the generator by
adding or removing shims under the machined feet.

Figure 7 Alignment Check
Following the final generator adjustment and runout check, remove
the horizontal shims from the adaptor flywheel housing, and move the
generator all the way to the adaptor. Then tighten the fasteners.
Recheck alignment. Make sure angularity (face) total indicated runout
does not exceed 0.005" per inch (0.05 mm per cm) of generator shaft
diameter and parallel (radial) total indicated runout does not exceed
0.005" (0.127 mm) TIR.
Torque the fasteners to the value shown in Tables 5 and 6.
IMPORTANT: Clearances between the
adaptor pilot and the flywheel housing
recess are designed to meet the tolerance
of 0.001" to 0.015" (0.0254 to 0.381 mm).
