Disassembly of Large Frame Units
NOTE: Steps 2, through 6 can be done independently of one another.
1.
Remove any electrical connections to the generator.
2.
Remove solenoid cover (1). Disconnect the electrical connections carefully,
noting their relationships. If necessary, remove printed circuit board (7) from
solenoid cover. Note wire routing and connections for later re-assembly.
3.
If necessary, remove solenoid(s) (9 or 15) from top of housing. Note wire
connections for later re-assembly. (Step 2 must be completed first.)
4.
Remove AC brush assemblies (12 or 16) from unit. Brushes are not retained in
the assembly, so withdraw the assemblies carefully. Note wire connections for
later re-assembly.
5.
Remove DC brush access covers (14 or 18). Remove DC brush springs and
brushes. See the paragraph below titled Brush Replacement for removal
instructions.
6.
Remove fan shroud (21 or 25) by removing screws (22 or 26). If necessary
remove fan impeller (23 or 27) from armature shaft by removing C ring (24 or
28).
NOTE: Steps 7 through 13 must be done in the order presented.
7. Disconnect terminals protruding through terminal insulator(s) (16 or 20). Note
wire connections for later re-assembly.
8. If necessary, remove the terminal nut (39 or 43) from the negative battery post.
Note wire connections for later re-assembly.
9. Remove nuts (28 or 32) from tie rods (27 or 31)).
10. Remove rear end bell (26 or 30). The negative battery post is removed with the
rear end bell. See the paragraph below titled Brush Replacement for further
disassembly instructions.
11. Remove nuts (29 or 33) from tie rods (27 or 31)
12. Remove front end bell (25 or 29) and armature (39, 43, 44, or 48) as a unit.
Withdraw the components from the shell briskly to reduce the amount of
magnetic attraction to the armature.
13. If armature (39, 43, 44, or 48) is to be replaced, separate bearing (36, 40, 41 or
45) from front end bell (25 or 29) end bell with a rubber hammer (the bearing is
bonded to the end bell).
