Bosch Generator
Removal
Remove the generator and rear cover.
Unscrew the voltage regulator from the back of the generator and carefully pull it out.
Replace carbon brushes if their length is less than 5 mm. To do this, unsolder the current leads.
Check the wear of the contact rings, and if necessary, grind and polish them.
Clean the contact surfaces and check the elasticity of the contact springs; replace if necessary.
Installation
Insert carbon brushes "A" and springs "B" into brush holder "C" and solder the current leads.
To prevent solder from getting into the brush braid when soldering new brushes, hold the braid with tweezers.
Caution: Solder will cause the braid to become stiff and brittle and the brushes will become unusable.
The insulation should be clamped in the lugs near the soldering point.
After installation, check the ease of movement of the brushes in the brush holder.
Place and secure the voltage regulator first with one screw, then press it down and secure it completely.
Install the generator and tighten the V-belt.
