Axle shims

Skip Burney · Feb 15, 2017

Got my rear housing and axles in today but I had to use 3 paper shims on each side to get it right is that an excessive amount of shimming. I put Prussian blue on one axle end and kept shimming until I got no transfer to the bare axle. I got bluing transfer with 2 shims and some slight resistance and none with 3 so I am guessing I am good to go.

Did you wedge one side to apply outward pressure ? I don't see prussian blue measuring the minimum .004 and the maximum .006 ( numbers are from memory , could be wrong )

I would bet though , that your adjustment would work just fine .

Bound up tight with 1 shim, turned but really tight with 2 shims and worked fine with 3

I even thought about putting the axles in the lathe and slightly turning the ends of tem to get them perfect without shims

Do you have a dial indicator ? Sounds like you got it close enough .

I have 3 or 4 in my machine shop but I didn't bother with them. I shimmed it till I got no blue transfer and the bearing just felt right. If it has to much preload you can actually feel the bearing rolling hard but when you have it right the bearing will roll but you feel the entire bearing roll smoothly. I know it sounds crazy I just a 66 year old man who is set in his ways.

You know I was wondering what the big deal with the clearance anyway, it is way past the splines and out on the tapered end of the axle and there isn't any thrust on the axle I mean what would it matter if you had 1/16th inch clearance between the ends of the axles

Not an engineer by any means , My guess is a tappered roller bearing with proper preload would transfer force through the rolling pins in the 12 O'Clock and 6 O'Clock positions . Not enough preload and you are only getting transfer on the 12 O'Clock rolling pins . At operating temp ??? there may be no clearance .
