Removal and installation
Removal
1. Disconnect the cable from the negative battery terminal.
2. Remove the drive belt. See chapter "Mechanical part of the engine".
3. Disconnect the connector (A) from the generator.
4. Unscrew the terminal "B" nut (B) and disconnect the terminal "B" wiring.
5. Remove the wiring clamp (C) from the bracket.
6. Remove the upper generator mounting bolt (D).
7. Remove the lower generator mounting bolt (E).
8. Remove the generator from the vehicle in an upward direction.
Installation
Installation is carried out in the reverse order of removal, taking into account the following:
- Install the generator and check the belt tension. See chapter "Mechanical part of the engine".
Caution: Tighten the terminal "B" nut with care.
Disassembly and assembly
Disassembly
Back cover
Note: The rear cover may be difficult to remove because the outer ring of the rear bearing is secured with a ring. To make it easier to remove the rear cover, heat only the bearing housing area to approximately 30°C using a 200W soldering iron.
Attention: Do not use a fan heater, otherwise the diode assembly may be damaged.
Front cover
1. Secure the rotor in a vice.
Attention:
- But damage the rotor
- When securing the rotor in a vice, place copper strips or a thick cloth underneath.
2. Using a suitable tool, remove the cap from the pulley.
3. Using the generator pulley adapter (special tool) remove the generator pulley.
Assembly
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.
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.
Note: Do not damage the sliding surface of the slip rings.
Examination
Checking after disassembly
Checking the rotor
1. Checking the resistance.
Resistance. See below under "Technical data and specifications".
- If the measured value 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 below. "Technical data and specifications".
- If the measured value is different from the norm, 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.
