What caused this? and mission creep

(quoted from post at 06:25:36 04/16/16) I split a 1952 8n to fix a loose oil pickup tube and found this Any ideas what caused this foamy white residue on the pan.


This is from condensation forming inside but probably resulting more from actual water getting into the oil from the outside. When we drained our oil shortly after getting our 9N and 8N, both came out like a runny vanilla milkshake.

From what we have read, water often gets into the transmission and rear end through the shifter since it only has a rubber cover that only semi-protects it to keep water out.

We ended up removing the transmission cover where the shifter is located on top as well as the round inspection covers located on each side of the tractor that has 6 bolts in them...this gives access to see down into these areas and clean out any sludge that has built up over the years. It also provides a better way of pouring kerosene into them and slushing it around to help clean out the contaminated oil.

We use Napa's mineral gear oil GL-1 SAE-90 part # NHF 65205 over what tractor supply sells

GL-1 doesn't contain any phosphates which can break down any components that have brass parts in them.

I have two 8n's and both of them will get the water in the trans and I believe it is all from condensation. I NEVER work them in the rain and they are ALWAYS parked under cover.
