STATOR
(1)
Conduct on stator examination over the stator and confirm
whether the conduction exists with the lead-wire of the winding,
if not, replace the stator assembly.
(2)
Check the grounding of stator winding. Confirm whether con-
duction exists between the winding and stator iron core, if yes,
replace the stator assembly.
RECTIFIER
(1) Check the positive rectifier
Check whether conduction exists between the positive rectifier
and the wiring terminals of stator windings with a multimeter. If
conduction exists in two direction , the diode is breakdown, the
rectifier assembly should be replaced.
(2)
Check the positive rectifier
Check whether conduction exists between the negative rectifier
and the wiring terminals of stator windings. If conduction exists
in two direction, the diode is breakdown, the rectifier assembly
should be replaced.
(3)
Check diodes group (3 diodes)
Connect the two ends of the diode to the ammeter, check whether
these three diodes are switched into conduction.
If conduction doesn
t exists bidirectioinally, the diodes are
damaged, and the radiator assembly should be replaced.

BRUSH
(1)
If the brush is worn out to the wear limit line, replace brush by
taking the following steps:
(2)
The brush may be taken off by burning off the soldering joint of
the brush lead-wire.
(3)
While mounting new brush, you should burn on the brush lead-
wire with the brush being pressed into the brush holder.
NOTES FOR ASSEMBLY
MOUNTING OF ROTOR
(1)
Before mounting the rotor onto the rear cap, insert a steel wire
into the small hole on the rear cap to lift the mounted rotor, and
then pull out the steel wire.

ESSENTIALS FOR DISASSEMBLY
DISASSEMBLY OF MAGNET VALVE
(1)
Knock down exciting coil from terminal M of the magnet valve.
DISASSEMBLY OF ROTOR AND BALL
(1)
Do not drop the ball mounted on the end of bearing while
disassemble the rotor.
DISASSEMBLY OF SNAP SPRING AND CHECKING
RING
(1)
Push and press the checking ring to the free engine clutch with a
proper casing tube to separate it from the snap spring.
(2)
Dismantle the snap spring with a snap spring clamp first, then
disassemble the checking ring and free engine clutch.
CLEANING OF STARTER COMPONENTS
(1)
Don
t clean the components in detergent. Immerging the yoke
and exciting coil assembly or rotor into detergent may damage
their insulation property.
(2)
When these components are contaminated, use a piece of cloth to
clean them.
(3)
The driving parts may neither be immerged into detergent.
Because free engine clutches have been lubricated before leaving
factory, if you clean them in detergent, the lubricant inside the
clutch may be washed off.
(4)
The driving part should be cleaned with a brush dipped with
detergent, and toweled off with cloth.
CHECK
COMMUTATOR
(1)
Put the rotor on a pair of V-blocks, check its radial jumping with
a dial gage.
Standard value: 0.5mm
Limit value: 0.1mm
