NOTES FOR DISASSEMBLY
SEPARATION OF STATOR AND FRONT CAP
(1)
Insert the screwdriver into the gap between front cap and stator
to separate the front cap from the stator.
(2)
If it is hard to separate them, lightly hit the front cap with a plastic
hammer and prize it with screwdriver at the same time.
NOTES:
Don't insert the screwdriver too deep lest the stator winding
is damaged.
DISASSEMBLY OF GENERATOR PULLEY AND ITS FAN
(1)
With the pulley end upwards, disassemble the pulley after fixing
the rotor with a bench clamp.
NOTES:
Do not damage the rotor.
DISASSEMBLY OF STATOR ASSEMBLY, ADJUSTOR
AND BRUSH STAND
(1)
Knock down the stator with an electric iron (180
250W), such
operation should be finished within 4 seconds lest heat is con-
ducted to the diode.
(2)
While disassembling rectifier from adjustor, burn off the part
welded to the rectifier with the electric iron.
Ensure not to conduct the heat generated by the electric iron
to the diode for a long time.
Do not let the diode pin overburden forces.
CHECK
ROTOR
(1)
Check whether the rotor winding is switched into conduction and
confirm conduction exists between the slip-rings. Measure the
resistance of the rotor. If the resistance is too low, it means the
circuit is shorted . If there exists non-conduction or short circuit,
replace the rotor assembly.
Standard value: 3
0.5
(2)
Grounding of rotor winding. Check if it is insulated between the
slip-ring and iron core, if not, replace the rotor assembly.
