[AT] WC transmission, dodged a bullet

Drained 7 gallons of water out of a DC Case I restored.  Had to replace
every bearing in the transmission.  Antifreeze will damage the bearings
fairly quickly, so you don't want to use that.

About 1/2 a percent of water in the oil is enough to cause problems with
hydraulics, brakes, etc.  You can't tell that there is even water in the oil
at that level.  That is about 7 oz in 10 gallons.   It takes at least 2%
water to even see it in the oil.



=========================



We had some extensive discussions about this on all tractors many
years ago. It is a shame that the housings were not built with a
simple bleed off valve at the low point where you could bleed off the
water on a regular basis after the tractor had been sitting for a
while. Unfortunately most drain plugs are located where any valve
installed there would be at risk of being broken off. In most cases I
don't believe that the lube that has gotten a little milky will do any
really serious harm to the tractor (or 60% of them would have fallen
apart by now) but that ice can wreak havoc.
I don't know if we currently have any chemical specialist on the
list... but I have wondered at times if a dab of some sort of product,
even maybe common antifreeze, might be able to avoid ice forming and
prevent rust without chemically destroying the lube???
I occasionally pull the drain plug on one for a few seconds to drain
out the water after one has sat long enough to separate. The trouble
is that simple plug can suddenly become the hardest thing on the
planet to operate and sometimes absolutely refuses to thread back in
to stop the lube from coming out. Its one of those jinx things like
saying out loud that something is running great.   :-)
