M1031 starter

[jcollings]

Asking who has seen different size shims on this starter for the 6.2 diesel.
I seen someone pulled one off of a 6.2 civilian type engine and that shim was probably a .150 thousands.

Thank you to everybody that might have some information.

Is yours a reduction gear or direct drive starter motor? The redux units almost all say DO NOT SHIM. The CUCV and HMMWV manuals have a great part about how to determine if you need to shim and how much as well.

After measuring that shim I was wrong, it was only .090 thousands.
It's such a bear to get in there with the differential right in your face. I was wondering if there should be a tooth to gear gap for wire measurement that it should be. definitely don't want to sheer off some fly will teeth if you know what I mean.
Is that discussion in a TM?

I'm not sure which starter it is, I think it's the gear reduction style.
When turning it over/cranking it just sounds a little bit tight to myself, it looks like there's 2 thin shims in there now.

Is this the document you're referring to??

Yes, that is the procedure. There was only the direct drive starter motors then so shims were used.
