Disassembly
Back cover
Attention:
- The back cover may be difficult to remove because the outer ring of the back bearing is secured with a ring. To make it easier to remove the back cover, heat the bearing housing area with a 200W soldering iron.
- Do not use a fan heater, otherwise the diode assembly may be damaged.
Rear bearing
Attention:
- Once the rear bearing is removed, do not reuse it. Replace it with a new one.
- Do not lubricate the outer race of the rear bearing.
Examination
Checking the rotor
1. Resistance test Resistance: See section "Technical data and specifications".
If the resistance is different from the norm, replace the rotor.
2. Insulation testing.
If there is continuity, replace the rotor.
3. Check that the slip rings are not worn.
Minimum outside diameter of slip ring. See section "Technical data and specifications".
If wear exceeds normal limits, replace the rotor.
Checking the brushes
1. Check if the brushes rotate freely.
If they are sticking, check the brush holder and clean it.
2. Check if the brushes are worn out.
If the wear has reached the limit line, replace the brush.
Stator check
1. Conductivity test.
If there is no conductivity, replace the stator.
2. Checking the conductivity to ground.
If there is conductivity, replace the stator.
Assembly
Fitting the ring into the rear bearing
Secure the ring into the rear bearing groove so that it is as close to the adjacent area as possible.
Caution: Once the rear bearing is removed, do not reuse it.
Installing the back cover
1. Install the brush assembly, diode assembly, regulator assembly and stator.
2. Lift the brushes with your fingers and install them on the rotor.
