1972 Duster Build with my Daughter
The original solenoid was bead blasted, cleaned and checked out. It had about 2-3 ohms which felt about right.
Insert the wire through the hole in the plate and feed the small stud through the plate with a fiber washer between the nut and plate for a seal.
This is a very important part. This cardboard insulator keeps the long bolt that holds the magnet frame on from shorting out on the wire. On the Coronet I put heat shrink tubing on the bolt to help since the original was deteriorated. This one was in great shape.
Wrap the wire from the solenoid onto the post and solder. Then bend it over to make sure it won't contact the rotor when it spins once installed.
Polish the slip rings with 1500 grit and use a hacksaw to dig the grooves back into the mica.
Soldered on.
Here is how the brushes are held. The retainer hold the brushes back. When you push in the armature the ring pushes down and just ends up rattling around in there forever.
Slide the rotor/armature into the magnet housing from the front and start the assembly down the brush holder. Don't go all the way! You have to get the brush wire bolted to the bus bar in the magnet housing.
See how it fits behind the cardboard insulator so it can't hit the housing.
There is an index tab in the magnet housing that fits into a square slot in the brush housing so the are clocked correctly.
