1972 Duster Build with my Daughter
Wiper motor day. I did get a 3 speed motor with the Dart but I decided to keep the factory 2 speed. These are plentiful and you can get new harnesses for them. The Coronet has a 3 speed and since I have driven it in the rain exactly 0 times in 2.5 years I don't see the point :) .
So sit back and lets restore a 2 speed motor... These are so simple... remove the screw holding the resistor to remove it then remove the 2 screw holding the armature can/magnets and pull the armature out of the housing. Be VERY careful with the springs for the brushes don't loose them. Next drill out the 6 rivets holding the cans together and then the 2 rivets holding the brush plate down. Pull the snap ring from the shaft and pull out the main gear from the rear clamshell. Note the order of the washers/wave washers.
The washers go, thin next to the gear, insert in clamshell, thin against outer bushing in clamshell, wave washer then large washer. Lastly the snap ring.
In the armature there are 2 identical washers that sandwich the wave washer.
The part number tag was still on this one.
Polish up the slip ring and scratch the groves in a bit deeper with a small screwdriver tip.
Now the fun part. Old plastic that is pressed on a shaft WILL split after 50 years regardless.....
