Starter & Shims

[Rich72C10]

Okay, just want to confirm this You Tube on How to install SBC Starter Shims.

My neighbor, who is a Chevy guy, stopped me after I started my truck. He said, hmm I think you need some shims on your starter. I thought myself it sounded scratchy but figured it was a normal sound for a old truck's starter.

I just popped under my truck, removed my cover and used a 1/8 Allen Wrench. I can just move my Allen Wrench between the Armature shaft and the flex plate - just enough to hear a tap on each side.

Am I doing that right, with a 1/8 Allen Wrench? Then just shim the outside bolt where the solenoid is at?

I can get my 9/64 Allen Wrench in, it almost turns but will not. The next size up, 5/32 will not go in at all. So I guess I have a 1/64 gap or 0.015625 gab right now. The teeth do not seem mangled...

I see that O'Riley's has shims, Dorman Starter Shims Part Number: 02335.

Thanks!

Edit: forgot my photos. The Allen Wrench I am using is my larger 9/64.
