18.With the 5/8" wrench, remove the four bolts mounting the stator/end bracket assembly to the generator frame. Note the "drill spot" for reassembly. See Figure F.18.

19.With the 7/16" wrench, loosen (do not remove) the generator brush holder clamping bolt. Note the drill spot for reassembly. See Figure F.18.

20.Carefully pry the stator/end bracket assembly away from the generator frame.

NOTE: The generator brush holder assembly will also be removed.

Replacement

21.Mount the stator/end bracket assembly to the generator frame. Line up the mating parts at the stator end bracket drill spot. Tighten the four mounting bolts with the 5/8" wrench.

22.Check armature air gap. Minimum gap is

.035." Loosen the four mounting bolts; adjust and re-tighten if necessary.

23.Tighten the generator brush holder assembly with the 7/16" wrench. Note brush holder drill spot.

24.Connect the four heavy cables from the generator frame coils to the generator brush holders.

25.Install the eight commutator brushes according to how you marked their posi- tions at disassembly.

26.Attach the black lead to the positive termi- nal of the field rectifier bridge. Attach the red lead to the negative terminal.

27.Attach the white auxiliary power lead to the 115 VAC receptacle. Attach the red auxiliary power lead to the CB4 circuit breaker. Attach the black auxiliary power lead to the current transformer. Tape the bolted connection.

28.Connect the two yellow leads to the field bridge and to the field fuse holder. Connect the white and yellow wires at the in-line connectors.

29.Install the commutator wrap-around, the bottom alternator cover, the battery, and the alternator brush holder assembly.

30.Install the alternator rotor according to the reassembly directions in the Alternator Rotor Removal and Replacement pro- cedure. Before installing the case top and sides, replace any cable ties cut for disas- sembly.
