As before, I was having problems with the right side track slipping after the clutch was redone and I installed a new oil seal around the shaft due to oil getting into the clutch housing. When I removed the top of the clutch assembly oil is once again getting into the clutch housing. I am asuming this is why the clutch is slipping and making the right side track not move when pushing. Is there another place that oil may be getting in or is the seal around the shaft the only entrance for oil into the clutch housing. I only replaced one seal around the shaft as I did not see any other seals between the clutch housing and rear end. Any info would be appreciated. Thanks.

There is a seal on both sides of case input shaft and output.

In such a short time to have oil migrate into clutch seems odd. Is the drainhole in the bottom of housing open to allow anything to flow out?

Is has a large barrel plug in it - drill a 1/2" or larger hole to allow drainage if you do not want to leave full hole open - mice like ot find places to hide so not a good idea to leave large holes.
