milky transmission oil

jamesh · Sep 13, 2021

I recently purchased a 1984 International(Dresser) TD 12 dozer.After running a few days it would not move.I checked transmission oil and found it to be extremely milky.I cleaned suction screen,replaced trans oil filter, and changed oil.It ran fine for about a week then blew the seal between the transmission and driveline.I once again cleaned suction screen(extremely clogged)and cleaned filter.Oil is still very milky.Is there some other reason other than a clogged suction screen to cause the seal from blowing out?I plan on changing oil again and replacing seal and hopefully getting rid of water in oil.Any input would be greatly appreciated.

Look on top of the drive train for any breathers it may may and see they are free, have you noticed if the oil is foaming, have you found and fixed where the water is getting in, when you say it blew the seal out does that mean that it actually did or is the seal just leaking, if it blew the seal out the pressure would be high inside, was the oil level right.
