b. The brush springs should
have sufficient tension to
provide the proper pressure
between the brushes and
commutator after the unit
is assembled. This may be
checked by placing the
armature and commutator end
frame together in their
normal operating position.
and then placing the
brushes in their holders
with the springs in place
so that the tension of the

can be measured with a
spring gauge. Correct
spring tension should be 36
to 40 ounces (10 to 11 n).
Replace springs if tension
is not correct.
