Trying to find the correct part #s for which axle seals are the correct ones. Can't seem to get a correct breakdown. Looking to get brakes working again they are most likely soaked in earl, both sides final drives leaking.

K623409?

I just looked in the free parts manual for the 990 which is at the following google site:

You could also try the Case online parts search. See if this link works for you:

It may not be the oil causing them to not work. It may well be plain old dust and dirt and rust keeping things from working. That's basically allt hat was wrong with mine. I put in the new brake shoes I bought anyway, but cleaning up 40 years of crap made a world of difference.

Have you ever gotten this problem solved? The seal went in my 990, in the process of replacing them. I have the seals, as far as I know I have the correct ones.
My problem is I do not know if the final drive, slides off after unbolting it or if there is some sort of lock ring in side the end cover?

On the DIF lock side (right) the diff lock pedal must be depressed and locked down or the diff lock sleeve will fall off its shift fork, a pain to get back in place but doable.

yep on the right side. So lock the diff lock peddle down before sliding the final drive off.. Is that what you are saying?
But does it slide right off, leaving what would be the axle, I guess would be the best way to describe it..
