How hard is it to open the delco remy starter/gen and replace brushes? I got the kit coming from ebay that has the 2 brushes and a bearing...
Just worried about taking it apart!

I think there are 2 long bolts that go from 1 end plate to the other. Brush replacement should be easy. The most problem you might have is getting the armature back in place because of the brushes being in the way. I have seen some S/G's with a hole for a wire or paperclip to hold the brushes tight against the springs to make assembly easier.

Some springs can be used to hold the brush in place then once assembled the spring can be put into place for tension on the brush.

Yep,I always use a paper clip.

Its not hard at all.  I do it myself in about 15 minutes, and that includes cleaning out and polishing up the armature.

I just happen to be doing the same thing right now  ( my kit hasn't arrived yet either ).

Here are the parts when taken apart.

The brushes are located right in the back of the housing.

Once you get the new brushes mounted in the housing, slide the armature in from the front and just spread the brushes out with your fingers and let them slip over the end of the armature.

While you got it apart dont forget to inspect the bushing and drench the felt wick with oil before you put it back together.

This is a good thread. :thumbs:

Maybe it should get pinned, over in the mechanical forum.

 

I've got a couple of S/Gs sitting around, that I've been

wanting to tackle, but I've been a bit leery.

 

I'm guessing that there are different models of S/Gs, and different kits

required. Maybe some of you S/G repair veterans can fill us in on that?

 

Some time this fall, I hope to tackle mine, and use this thread as a guide.

I've found there to be two different styles.

One has bearings on both ends and the other has a bearing on the front and a bushing on the rear.

Correct, Many were the Bearing/ Bushing style instead of the double bearing style though. It was probably a cost cutting thing as I believe the double bearings Starter's came out first then later were replaced by the Bearing/Bushing combo.

Well just did mine. I only installed the brushes. I was worried i would break the back plate forcing the bushing out. And couldnt tell how to replace the bearing. I checked and the bushing end and bearing end had no play. But brushes were half the size as the new ones.
