Grinding starter

[vseventyone]

I am still having starter trouble. After about two weeks of having my new 350 in the gear reduction starter started to grind on the flexplate. I replaced the starter, then I replaced the flexplate today. I have tried shims but they do not help. It did work great for two weeks with no shims or anything. The only thing I can think of is an electrical problem. From the looks of the new flexplate it looks like the solinoid is not fully engaging. Because one time when I tied to start it I could hear the starter spining but nothing was contacting. Since it is the second brand new gear reduction starter that has done this I am beging to think that it is an electrical problem. Has anyone experienced anything like this before? Thanks for any suggestions and advice.

I just replaced my flexplate I dont know why it wears out so quick?

Thats the thing. I replaced the flexplate and on the first time it grinded. I know the new flexplate is not worn. The old flexplate itsn\'t worn too bad either. I have tried all mechanical routs and the only thing I can think of is electrical. Before I tear my starting electrical system apart I was wondering if anyone had any similar problems.

Hi. Do you have the correct starter bolts? Chevy starters use metric and us size. I am talking about the bolt shaft not the hex head.The wrong bolts alow the starter to move, maybe this is why so many people wear out flex plates. http://www.s10v8.com/images/smilies/icon_smile.gif

You can run a momentary push buttom between your starter and your battery. Make sure you use at least 10 gauge wire. This will bypass you trucks electrical system. I had to do this to mine. For some reason in the summer my truck doesn\'t like to start with the key. Hope this helps....

Carguy1959, did yours do the same thing or did it not want to start for other reasons ?

I am using 3/8 x4 1/2 x 16 bolts I will pull the starter off and check to see how much play I have. Thanks for the advice.

Mine just will not turn over with the key in hot weather. Haven\'t bothered to check the wiring when it\'s hot, just mounted a switch under the steering columb. It did it last summer, thats when I installed the switch. Had a 4.3 at the time. Put a 400 in last winter. Started every time with the key. Now the last week (90 degree weather) It\'s doing the same thing again..
