TP-6053 7/0448 Section 9 Generator Disassembly/Reassembly
4. Inspect the O-ring in the end bracket bearing bore
and replace the O-ring if damaged. Use a sling to
support the stator assembly while installing the
stator over the rotor. Be careful not to damage the
rotor. SeeFigure9-9.
5. Install the four overbolts (the two long bolts in the
lower holes). Check that the alignment marks on
the stator housing and locator plate match. See
Figure 9-10. Tighten the overbolts to 40 Nm
(30 ft. lbs.).

6. Use the hoist to raise the alternator end. Remove
the wood block from under the locator plate. Lower
the generator set and install a bolt, a large washer,
two small washers, and a locknut in each
vibromount. Tighten the mounting bolts to 28 Nm
(20 ft. lbs.).
7. Apply antiseize compound to the keyed end of the
rotor shaft. Bring the rotor leads through the bores
in the armature while installing the armature on the
shaft. Check the keyway of the shaft and key of the
armature for damage. Install the armature
retaining bolt and washer.
8. Use screws and lock washers to install the rotor
leads to the rectifier board at the positive (+) and
negative (--) terminals.
Note: Position the lock washers against the
rectifier board.
9. Install three spacers and bolts to mount the rectifier
board to the armature.
10. Install the exciter field using four bolts and
washers. The field leads are at the top. Connect
the P6, P7, and F1 connectors. See Figure 9-11.
