Take a coat hanger and make a finger loop in one end, then about 3" straight, then a 90* hook about 5/16" long. Lift each spring, the pull the brush back enough to cock it to the side in each brush holder. Slip the parts together then tilt each brush until it slips down into place. Be sure the spring is centered on each brush. I'll see if I have some parts laying loose, so I can take a picture.
The armature for my starter doesn’t have any grooves I can see the lines but I really can’t feel them with my fingernail like I can with my generator. Is this OK or should it be replaced?
The picture is really deceiving where the brushes ride it is very smooth.
I'm going to be doing some chassis work and I'm limited in the space dept. so a spray booth would be difficult to achieve. Has anyone had any success using a black chassis paint with a bristle or foam brush that does not leave a "brush trail"?
I thought it would be a good idea to have working spare parts for my car in case of a problem and I would be ready with a spare. I purchased a box of starter and generator parts from the Steve Wastler Estate Sale which included a starter with Bendix drive. It was rusted and the armature would not turn. After an afternoon of liquid wrench, hammering and prying I was able to get the armature out....
Today I finally got around to rebuilding a early style starter. I disassembled everything, cleaned, inspected, and mic’d the bushings. Replaced the Bendix end bushing as it was totally worn out. The brush end bushing was fine. The starter had 4 thrust washers installed all at the opposite end from the brushes. After taking a lot of measurements I installed one new washer at the brush end and one...
In the red mechanics handbook, he states.”Using an ohm meter, check continuity of the brush holders to the end plate. Only the movable “adjusting” brush holder should be grounded. If either of the other brush holders is grounded to the end plate, check “why”.
Then, in the troubleshooting and diagnostics book, he says the opposite .”This third brush like the lower negative...
I evidently have an early starter that has the thin walled bushing on the long shaft. Can that armature be used with the later ends? It appears the id and length are the same, so why not?
Generator Brushes and Adjustment and How It Works.
By :: Tom Wesenberg
I'm asked quite often about brush adjustment and how they work, so hopefully these pictures will help.
The first picture is a cutaway taken at the Model A museum at Gilmore Auto Museum in Hickory Corners, Michigan. The second picture shows the 3 brushes. This happens to be the style...
