2) Checking stator coil for proper insulation
Connect the circuit tester between any terminal of the stator
coil and the stator core. If continuity is noted, it indicates that
the stator coil is shortcircuited inside, and the stator must be
replaced.

BRUSHES
1) Measure the length of each brush. If wear exceeds the
wear limit, replace the brush. Each brush has the wear limit
mark on it.
Brush length:
Standard
16.5 mm (0.650 in)
Wear limit
8.0 mm (0.31 in)
If the brush pigtail (lead wire) is soldered, use a soldering iron
heated to 300 to 350°C (572 to 662°F) and paste without
oxygen.

2) Checking brush spring for proper pressure
Using a spring pressure indicator, push the brush into the
brush holder until its tip protrudes 2 mm (0.08 in). Then
measure the pressure of the brush spring. If the pressure is
less than 2.059 N (210 g, 7.41 oz), replace the brush spring
with a new one. The new spring must have a pressure of
2.942 to 3.923 N (300 to 400 g, 10.58 to 14.11 oz).

ASSEMBLY
To reassemble, reverse the disassembly procedure, noting the
following points.
1) The rear bearing has an eccentric groove on its periphery.
Fit the lock spring into this groove so that the projecting part
is in the deepest portion of the groove. This will reduce spring
projection, making reassembly easy. Also, it assures greater
locking effect, since the spring will be free from undue force
during reassembly. The deepest portion of the groove has
chamfered edges for easy identification.
