shims on bull pinion carrier

Does any one kknow the exact thicknessses of all three different shims for carrier and does anyone know where I can get some of the thin ones. The m parts book shows light medium and heavy the light is no longer available from ih. Thanks
 
Cut them out of steel cans. Various thickness shims are pretty easy to make. Use a micrometer and measure the existing shims to predict the thickness of the thin ones. Do not use aluminum or galvanized tin. Shimming is done to preload bearings and is not made un reliable with nice round home made shims if none can be found. Jim
 
You would need a pretty big can. Just because one parts guy tell ya that oh they don't make that anymore , that does not mean that there is not some still layen around collecting dust. , it just means he does not want to be bothered looking . Good OLD parts men are but dead and gone . People like Clyde Burkshire may have then but Clyde is in his 90's or Bates Corp.
 
No not off hand . And i can not go looking anymore as the two places around here that had a bunch of old M's scrapped out are long gone . And other couple places ya might try are Roberts Farm Equipment in Camden Ohio (ask for Dan) or Andersons tractor Parts in Bluffton Ohio.
 
I measured within .0005 the following. .010, .015 and .031.
Tend to save shims when working on them every now and then.
 
I know it is not for an M, but in the parts book for my Super A, I found the following information:
Shims for Differential Ball Bearing Retainer
0.004" fine
0.007" light
0.015" medium
0.030" heavy
I found all of these thicknesses being used between the two retainers of my Super A.

I also looked into the CaseIH on line parts book for the Farmall M differential and rear end. There only three shim thicknesses are shown: light, medium, and heavy; no indication of the thicknesses in inches being given. I'd presume the thicknesses to be the same as listed for the Super A.
The larger size of the rear end and its components supposedly did not necessitate the use of "fine" shims.
Jives with the information provided by D Slater.
