Maintaining and servicing your AEC switcherlocomotive
Lubricating your AEC switcher's Pullmor motor armature
Y
our AEC switcher engine will
require occasional lubrication of
its Pullmor motor armature. If you
hear excess noise during operation, or
if the locomotive slows down inter-
mittently, you may need to oil the top
armature bearing.
Start by separating the body shell
from the frame; remove the cab
mounting screws (see illustration on
page 9). Unscrew the set screw shown
below and apply a small amount of
Lionel oil (two drops) in the armature
shaft hole. Reinstall the set screw.
Proper set screw adjustment can be
checked by gently rolling the engine
10
10
wheels back and forth by hand. As
you do this, observe the up and down
travel of the armature,and brushes.
Tighten the set screw until the travel
of the brushes or the armature is
about .010" up and down (thickness
of three sheets of paper). When the set
screw is correctly adjusted the travel
up and down of the brushes and
armature will be barely visible.
Finish the job by reinstalling the
body shell and reinserting the cab
mounting screws.
Note: Due to gearing, you will not
be able to turn the motor armature by
rolling the wheels
