Questions on the rear axle seals? And the outer ends.

[color=black:bea3c72846]Hello all, I've been working on my 51 tea20 that has sat for a few years & I see that from the angle it was parked on that some diff fluid has leaked out . So I took the wheel & drum off to see what I could fix, well at the end of the axle there are 3 brass/bronze metal gaskets? Why 3? Every schematic that I look at only shows one? Could they be acting as shims?

Now on the wheel bearings there was no grease at all? How do you get them out? Do you have to pull the bushing or whatever it is above it & if so HOW?

Is there a torque value for for the bolts/nuts on the back of the brake backing plate? Thanks for your help.[/color:bea3c72846][size=18:bea3c72846][/size:bea3c72846]
 

The copper gaskets are indeed shims . It is really important to make sure that the clearance between the axle shafts is correct .

This fellow has a series of short clips that show some pitfalls .
Best to consult the factory manual .

But you did answer one of my questions about the shims,thanks for that. I never had any noises or problems except for the leak onto the brakes.[/size:e4d1a8219f]

Trucker , Look at his other clips as well ,

This one shows the excess movement caused by not shimming the axle correctly after a bearing and seal change .Some TEA20 tractors have five or six of these shims in place .
There is a specified gap that should be preserved between the axle shafts , I can't remember what it is though .
The opposite of too much space is to have the shafts touching which leads to grinding and component failure .
 
After you finish, jack up both rear wheels. Turn one forward. Other should turn backward. If it turns same way, you need
another shim, as it's too tight. If it doesn't turn, it's too loose, remove a shim. I assume the video says something along
those lines....?
 
thanks all, the 1st part of my question has been answered very well, :D :D thanks.

Now on to the wheel bearings,on the axle I pulled to see why it was leaking, there was no grease at all on the bearing? Is that normal? Do they get lubed by slosh from the diffs? Or are they supposed to be greased? And any guesses as to why it was leaking? I couldn't see anything wrong.
