BRUSH SPRING
Inspection
Magnetic switch
1. Continuity (S terminal:M terminal)
Check for continuity between S and M terminals with ohm-
meter. Replace the magnetic switch it there is no continuity.
2. Continuity (S terminal-Body)
Check for continuity between the S terminal and the body
with ohmmeter. Replace the magnetic switch if there is no
continuity.
3. Grounding
Check continuity between M and B terminals with an ohm-
meter. Replace the magnetic switch if there is continuity.
.-.’
Brush and .brush holder
1. Insulation
Check continuity between each insulated brush and the
plate with an ohmmeter. Replace the brush holder if there
is continuity.
2. Measure the force of the brush spring with a spring balance.
3. Replace the spring if necessary.

Field coil
1. Check for continuity between the M terminal wire and brush-
es with an ohmmeter. Replace the yoke assembly if there
is no continuity.
2. Check continuity between the M terminal wire and yoke with
an ohmmeter. Replace the yoke assembly if there is con-
tinuity.
3. Check if the field coil is loose. Replace the yoke assembly
if necessary.
Armature
1. Check continuity between the commutator and the core with
an ohmmeter. Replace the armature it there is continuity.
2. Check continuity between the commutator and the shaft with
an ohmmeter. Replace the armature if there is continuity.

3. Place the armature on V-blocks, and measure the runout
with a dial indicator.
If the runout is not within specification, repair it with a lathe
or replace the armature.
Runout: 0.05mm (0.002 in)
Maximum: O.lmm (0.004 in)
4. Replace the armature if the outer diameter of the commu-
tator is almost at or less than the grind limit.
5. If the commutator surface is dirty, wipe it with a cloth; if it
is rough, repair it with a lathe or fine sandpaper.

6. Segment groove depth
If the depth of the mold between segments is almost at or
less than the minimum, undercut the grooves to the stan-
dard depth.
Depth: OS-0.8mm (0.02-0.03 in)
Minimum: 0.2mm (0.008 in)
Bearing (if equipped)
1. Check for abnormal noise, looseness, or sticking.
2. Replace the bearing(s) if necessary.
