Next field case comes off. Looks pretty good, but showing a rub mark on field pole shoe. Indication of loose shoe or bad drive end bushing. rear bushing was good. Pole shoe checked and is tight.

Next armature comes out. Commutator bars are narrow and showing more insulation between bars than I would like. Commutator is brush worn and out of round. I already know I won't be using this armature because of the narrow bars, but there is more armature problems to come. Took a light cut off the comm just to show uneven wear. Sorry pics aren't better. This is not the continues running problem either.

The rest of the armature is showing problems related to the continues running. Like the end cap, the armature is coated with the thick sticky grease restricting ease of movement of the drive. The grease is in the armature splines and on the shaft where the drive rides. Now comes the drive removal. When I looked close I could see the retainer was a bit forward, ( just slightly) but the retainer ring was still in the retainer and still in the groove. The thrust washer was very tight, like a push nut. It shouldn't be. it should spin freely and it would not. The thrust washer usually falls off. I needed to use locking pliers to twist and pull it off. Not good. Even though the ring and retainer were still together with the ring in the groove it was very sloppy. When pushing on the side of the retainer towards the end of the armature the retainer would cock on an angle. There should be very little play there and this was excessive. Removal of the ring and retainer show a few things. The ring was of a thinner wire size than it should be with less inside tension than it should have and this allowed excessive movement of the retainer. These problems are beginning to reveal why it would stay running. With the ring and retainer removed I can see the forward edge of the armature groove to be angled. Not good. It should be cut 90 degrees to the shaft. This with the poor quality retainer and ring is what caused the retainer and ring to move forward as shown in pic 3 of #38 post in this thread and noticed by Quick Silver in and me in post 40 and 41. The blurry pic is of the bad armature groove and the next is a good one. again sorry about the pics.

And finally the drive end housing. Where the retainer thrust washer rides against the inside of the housing there was excessive wear into the housing. The thrust washer should sit flush against the housing hole where the bushing goes. There was a wear divot there allowing the whole armature and drive to move forward of where it should be. I changed the housing with a new bushing. I strongly suspect the problem was the combination of the worn armature groove, the poor quality retainer and ring and the drive end housing. I will ship it back this coming week and wait to see what happens when it is reinstalled in the same vehicle. The worn housing is on the right. Left one is the replacement. Give her a spin and let us know what happens.

I'll pack it tight in case they try playing basket ball with it again.

It is on the way home. Should be there by Friday. I insured it for $100.00 in case they get brutal with it again. The Doc did all he could, so now it is up to you to give it some exercise and let us know how it works.

It arrived Saturday late afternoon in one piece. Thanks so much Mark. I will test it out when I have a chance but I am sure it will work great! Dave

I'm glad it works well for you. I returned the housing and the armature you had on the starter so you can see the problems with them. It would be a good idea to scrap them. If someone would use them in the future it will cause problems. The field case you have is worth a few bucks. 1107221. It is for a 1961-1963 Buick. You may be able to sell the field case alone and get enough to cover the cost of the other starter you bought and still have some left over. There aren't very many of the 1107221 cases around. Mark

He did take the starter to a starter shop and they didn't fix it. You must have skipped one of the 8 pages.

Are the wires connected to the correct posts on the solenoid?
I had this happen to my 442, crossed the wires. Also, be sure that none of the wires are touching the battery cable. |

He got straightened out. The solution is in the thread and you only have to go back one page..
