Dynamo brushes

Post by thunderbolt » Sun May 01, 2016 8:53 am

Hi all,

I need new brushes and springs for my 1939 350NZ. I think the German name is Kohlebürste and the part numbers are:

012115-0 Minus kohle

012894-0 plus kohle

Recommendations where to buy please,

thanks,

Chris

Hi Chris,

You will find them on German ebay. I have buyed them from this guy:

Otherwise they are ok, but the wire to the - brush is too long, so you have to cut it and fit a new ring clamp to it.

Thanks again Frank!

I've had the armature cleaned and tested but still no charge, so I will now fit new brushes.

all best,

Chris

Hi Chris,

Check also you have all the insulation washers and bushings in place under the two screws holding the brass + brush holder to the stator.
There shall be no contact between the + brush holder and ground.
