The fine art of starter shimming

[rcamacho]

Well, I finally got around to shimming my starter and installing a heat shield today. Background: 402BBC with Thorley tri-y headers. I'm running a 168tooth flywheel and offset mount starter.

The starter would spin but stay engaged. I ran through .020-.040-.060-.1-.12. The latter did the trick but I'm running all three shims. No grinding and the starter dis-engages cleanly now. . Given how hot the headers get running at low speeds off road I think the heat shield is a good $15 investment as well

Ya,shimming and the rear support bracket will make that starter last for YEARS.

I absolutely hate shimming starters when i was younger i always had good luck without having to use a one but now it seems i can't get anything without them needing it

My blazer still needs it fixed but i ran outta shims. glad to see you got yours fixed

I've not been able to locate a rear brace for the factory mini starter yet. There does not seem to be a place to attach one... Although the last one went 4 years or so and I replaced it under NAPA warranty.
