6. Tighten the rotor thrubolt to 33 Nm (24 ft. lb.). It
may be necessary to keep the engine flywheel
from turning while torquing the rotor thrubolt.
7. Reinstall the end bracket components.
a. Inspect the brushes. If brushes show uneven
wear or are worn to less than half their original
length, replace them. See Section 5.7.
b. Install the brush holder with shim onto the end
bracket. Verify that the brushes are not sticking
in the holder.
c. Verify that the brushes are centered on the slip
rings. If required, insert spacers between the
mounting surface and brush holder to center
the brushes on the slip rings. See Figure 6-16.
See Section 5.7, Brushes, for more
information.
d. Use the cable tie to secure the brush leads to
the end bracket.
