Make sure that carbon brushes sit correctly. Test positive brushes and make sure that they do not short or arc to ground. Replace worn or corroded
springs. If necessary use a spring balance to test spring force.
M18 Replacement of carbon brushes
Replace brushes if they are less than 11 mm (0.443 in) in length (new brushes are 16 mm 0.6 in).
-
use soldering iron to release old brushes
-
solder on new brushes.
Solder quickly and with sufficient heat. On no account must solder run onto wire because this would prevent brush sliding in holder and weaken brush
spring force.
