So I had a frozen up starter on my motor when I bought my truck. I bought a good starter from Bob K. It tested out good. I exchanged my nose cone and gear... all simple stuff. I get the motor all back together, crazy excited to crank it over, prime the oil pump and go to crank it.....nothing. Solenoid clicks on the firewall, brand new and a good one. I jump it directly to the battery...nothing.
I unbolt it and pull it out some, just in case it is binding on the flywheel or something, jump it straight to the battery...still nada, zip, zero, zilch. It was not a bad starter, I had it tested when I got it from Bob K. at a good AP store on a load tester machine.
Anyway, I pull it out and go to take it apart, and the end cap is frozen onto the shaft. There is no bushing is the end cap. Just steel shaft, on steel cap. It is so frozen on, I have to use a drift punch and a 32 oz hammer and beat the cap off of the shaft. There is some material transfer between the 2 pieces.
After cleaning everything up with a dremel and some emery cloth, I put it back together, but before testing it, I am inspecting the whole thing for a possible WHY, and I notice there some movement longitudinally on the shaft. First off, YES, I DO have the washer in there between the end cap and the armature.
What I notice is that there is a small groove on the end of the armature shaft just before the cone end bushing.
Is that groove supposed to have a snap ring or one of those round spring ring thingies?
I looked in all of my starter pieces from my other dismantled starter and I do not see one of those in my spare parts and pieces. I think there was one down inside the ratcheting mechanism and gear retainer area, but I can not remember for sure.
Any help on if there is supposed to be one just inside the nose cone would be appreciated.
