T-90

I am in the process of rebuilding a t-90 tranny, i have read a little about a sealed input shaft bearing, is it a good or bad thing, if its good where can i find one, thanks.

 

My take is that it isn't that big of a deal. Many jeeps have been running non-sealed bearings without much issue for years. The worst thing that happens is that a little 90 wt. leaks through the bearing and out the end of the endput shaft bearing retainer where the throwout bearing rides. I have never heard of this small amount of oil causing much problems with the clutch. As a result, I would just rebuild to stock and call it good.
