gear box

[molines2k8]

I'm working on a ZD28 with an RCKP - 72" deck. I am replacing lower bearing(output) and seal in the gearbox, and replacing the holder underneath. My question concerns the shim placement inside the gearbox. I didn't pay close attention on how many shims were in one hole as opposed to another. I have one hole for sure holding 2 shims. If I read the parts list correctly, it shows 2 shims on the output shaft. I'm positive there was only one shim in there when disassembled...and the shim looked a little worn on one side. The output shaft was loose, it would move around a little making me assume it was a bad bearing. The bearing was still good, the seal wasn't, and everything below that was gone....no grease.
My concern is how to tell where a shim is needed. The output shaft is still a little loose, not sloppy loose, but it doesn't seem right.....Any ideas?

Thank you so much for the link. This will come in real handy. We decided to take the box to the dealer to adjust it accordingly. don't have the tools to do what needs to be done. Thanks again
