I was concerned about the 4 brushes on my starter motor in my '48 coupe. After removing the rotor, as expected the springs holding the brushes against the rotor pushed the brushes in. They were OK, but one of the service manuals I read said to move the spring away from the brush, so you can have the brush out far enough to allow the rotor to go all the way in. I don't know how to do that. There is no lip to hold the spring. I tried removing the springs (carefully), to allow the brushes to be pulled totally away. However, there is so little room left to insert the brushes into their bracket and re-attach the spring. Any ideas? Thanks Steve

Steve: With the rear band off, lift the end of each brush spring and place it on the side of the brush holder. I use a homemade hook made from a piece of clothes hanger wire. When you reassemble the starter, and the brushes are in the holders and the end plate in position, lift each spring off the brush holder, and put it back on the brush, then reinstall the band.

Thanks. The spring needs to have something hold it away from the brush. The side of the holder is pretty narrow, and the spring tends to "jump off" the side easily, and puts the brush back in. Will try the hanger idea. Steve

Steve, Pull the brush out and let the spring rest on the side of the brush. After you install the armature, just push the brush in and the spring will seat on the back of the brush. Here is a photo showing the brush retracted. http://i168.photobucket.com/albums/u197/mercurytom/brush-spring-web.jpg

Aha! So you use the spring to hold the brush from going IN toward the armature! The pressure keeps the brush from going in! Thanks, Tom Steve

Worked like a charm (sort of). I had to remove it once because the holes in the armature didn't line up with the holes in the end piece. But by then, I had learned all of the tricks as to how to do it. Thanks again! Steve

Steve, that is one of the procedures that is so common to most of us that worked on these cars "in the day" that we tend to forget that it is not common knowledge. As always you are welcome.
