190xt and 200 ac pumps fluid into trans

The seals are junk. The rubber is glued to the metal and they come unglued.

can all these seals be replaced by just spliting at trans and torque hsg or does some of the trans shafts and gears have to be removed. I have a ac-202 shop manual but some of it is not too clear. I like both tractors and I'm going to fix both of them but I dont want to split and put back together without replacing the seals that could be the problem.

Make absolutely sure to not press the trans input seal all the way into the bore....press it in flush with the OD of the seal. Installing it too deep will block the weep/drain hole and it'll do the same thing all over. Also grease the PTO seals so the seals lip spring doesn't fall out of place when you pound it in place with a seal driver.

No. If it isn't made for two seals, are you sure the second seal isn't squezzing the first one too much?? My guess is you've cut the seals when sliding them over the sharp splines on the clutch shaft. Wrap the splines with black electrical tape tightly in a spirol (like a barber pole) keeping the overlap to a minimum starting at the far end of the splines and working towards the end of the shaft. Oil the tape with WD40 or similar and slide the seals over the splines without damage.

The housing of the Power director clutch has a hole in the bottom.  As stated do not drive the seal in too far.  Most books show incorrect direction of the seal although many argue as to orientation.  We install seal with wire towards the front . We also drill out the drain hole 2 drill bit sizes larger and redrill after seal is installed to insure seal metal does not  block hole. This larger drain hole will allow lube oil and excess oil from wear to drain and not rupture seal thus transfer oil.   Having said all this there are many units running with a 'balance' tube tying the two sections together.  a 1/4 " line tapped into both housings or drian plugs will allow the oil to 'level out' .    7000 tractors were prone to have the rear housing vent plugs clog and force oil transfer.  Also on 7000 s operating large hyd cylinders or multiple cylinders a rapid lowering with vent plugged  builds possible seal blowing  pressures 

Its interesting about the balance tube because when I found it was leaving pump side low and trans too full I put a pump from a 12v sprayer with a tube just a little longer than trans dip stick connected to a toggle switch and pumped oil back over about every 45 minutes or so. I have used this 200 for about 8 months this way without and problems as for as I know. the balance tube sounds like a better idea. I will try it on the 190xt. Do I just put fittings into drain plug holes and connect. I want to try this before splitting at first. I willsplit sooner or later on the 200 because that is the only problem with it.
