water in the hydraulic system

Postby jake1980 » Sat Apr 13, 2019 8:20 am

First a little history. I bought my 1300 D summer of 2016. January 2017 it blew the hydraulic pump. Thanks to the good guys at Hoye and people on this sight I was able to replace the pump. During this process I drained the system of fluid and found about 2 quarts of milky substance (water) in the fluid. I took out the screen and clean it up. I filled with clean fluid and ran the 3-ponit and front loader up and down a few times. I then drained out the fluid and replaced with clean fluid. That is the history.
I started it the other day for the first time in a few months and notice the system was leaking water milky fluid at the line hook up at the pump. Grrr. I pulled the dip stick and it has milky fluid on it. So I guess I am going to change fluid again. My question is. How is the water getting into the system? The tractor is under cover. I have attached a pic of the rubber boot over the shifter. It looks good. No cracks. I am afraid of the screen getting clogged and deadheading the pump and blowing it again. Help

condensation, or check #32 (vents on axle housing). Thinking they may have hoses on them. https://www.hoyetractor.com/CTGY/1300REARAX.htm

Winston my first thoughts were of condensation. In So. AZ. we have a lot of summer rains with temps over 100. The vents tubes are in place on each side of the seat. Are you suggesting that I replace the hydraulic fluid every year? Thank you

Thinking Arizona climate was dry but if you get water you need to replace. I don't have an answer why other than condensation.

Great Thxs Winston. Draining now. So far it is all in a liquid form. When I did this 2 years ago it came in in chucks like clabbered milk. Today the screen is covered in white oil. Last time it was plugged with white chunks. Thank you for everything.

Soooo, Fluid is changed and I still have that fluid leak at the pump hook up. bolts are tight. Drip drip when sitting there. Use the front loader and it streams out. Isn't there an O-ring here? Wondering when temps got down to the teens if the water in the hydraulic fluid froze and cracked the O-ring?

That kind of condensation requires high humidity which I'm sure you do not have in So. Ariz. Betting you just did not get all of the water out. Just find/fix the leak, no matter what it is. What kind of cover? Can rain blow in?
