2) Using ohmmeter, check that there is no continuity between
coil leads (2) and stator core. If there is continuity, replace
stator (1).
Brush and Brush Holder
Check each brush for wear by measuring its length.
If brush is found worn down to service limit, replace brush.
Brush length “a”
Standard : 16 mm (0.63 in.)
Service limit : 2 mm (0.08 in.)
Rectifier
1) Using ohmmeter, check continuity between each of upper
and lower rectifier bodies and each diode lead (2).
Check both directions by reversing probes of ohmmeter and
there should be only one-way continuity in each case.
If check result is not satisfactory, replace rectifier (1).

Drive End Bearing
Check that the bearing is not rough or worn.
End Housing Bearing
Check that the bearing is not rough or worn.
When removal is necessary, use bearing puller to remove end
housing bearing (1).
Replace Brush
1) Unsolder and remove the brush and spring.
2) Run the wire of a new brush through the spring and the hole
in the brush holder, and insert the spring and brush into the
brush holder.
3) Solder the brush wire to the brush holder at specified
exposed length.
Exposed brush length
“a” : 10.5 mm (0.413 in.)
4) Check that the brush moves smoothly in the brush holder.
5) Cut off the excess wire.
6) Apply insulation paint to the soldered area.
CAUTION:
Be careful not to distort cooling fan blade while applying
puller.
