why would a rear seal failure cause an input seal to fail as well?

Well, my experience is that when the seal between the tranny and transfer case fails, the added pressure in the tranny due to gear oil being pumped into the tranny from the transfer case causes the front seal on the tranny to eventually fail. If you look closely at the photo below, you will see the access plate wet with gear oil. I've had the gear shifter out and there is no oil being purged from the shifter mount on top of the tranny. I've had this happen to the front seal every time the tranny/transfer seal has failed. When the photos were taken, I had just installed the bypass and it took time for the gear oil that had already been purged to flow out. Since then I have noticed a reduction in the oil flow out the front seal and a dramatic reduction in the oil loss from the transfer case.orangefj45 said:why would a rear seal failure cause an input seal to fail as well?
The last time I tore them down everything looked fine - gears, bearings, washers, spacers, shims, output/idler shafts. Of course that was 30K miles ago (10 years) when I put a rebuilt Toyota clutch in, along with replacing all the seals. What other issues would you be refering to? Is there something else I should be looking at when I take eveything out to put the centerforce clutch in.?Mace said:You ever check the bearings in your tranny to see if they still are within spec??
If you are building up high presures in the tranny/tcase you have other issues..
What you said makes a lot of sense. I will be inspecting/measuring all the shafts when I rebuild the tranny, to make sure that they are not contributors to early seal failure.Mace said:The tranny/tcase is vented to the atmosphere. So, even if you add a ton of extra oil to the tranny cause the seal wore out pressures wouldn't increase significantly..
I would be more concerned with play in the input and the tranny output.. That would eat seal rapidly..
And you are eating seals a lot faster then you should.
For those with an Orion...Does just the case stick down 1/2" more, or does it lower the output as well?
If it's only the case, then the bottom of this skid plate should already be low enough.
So, then, since the drum is the lowest part of the case, and the Orion doesn't lower that, it would be logical to assume that this transfer case wouldn't need to be modified for it?
Thanks!
Here is another photo that shows how the skid plate marries to the edge of the frame.
