Hi all from Australia I'm new to Cat ownership but my dad owned a d6 d7 and a d8 at one time or another when I was a kid . I recently bought a 1954 d4 and found water in the gear box thinking that it may have worked its way down through the gear leaver as the machine had been sitting out in the weather for years. I drained the box than ran the machine for a short while with hydraulic oil in the box then drained it again. Filled her up with nice fresh gear oil and gave it a run a week later. Now the strange thing is when I checked the oil again it is all white and milky again. It has not rained so where could the water be coming from?
I have been loosing water out of the radiator but the water pump does leak a little.
Any ideas becouse I have none.
