5245 water in hydrolic fluid

[nick_wilburn]

Well i'll try to keep this short i got this Zetor 5245 from my grandpa it is a 1990 model. i need to change the hydrolic fluid which just so happens to be the tranny fluid i guess. it has water in it and looks like chocolate milk we have all seen this at some point in our lives. Grandpa said that the tractor always had this problem from the day he bought it he thinks it might be condinsation. I tend to beilieve he got water in it some how. Anybody have any ideas on this? Well he says it takes 80w-90 oil i thought that was kind of heavy for a hydrolic pump since the front end loader moves really slow. So if any one knows what it is supposed to take and how much of it he says it takes like 12 gallons but then i read somewhere that it should take 20. anyway if any one knows what oil i should use and how much let me know thanks

Use 15/30 SUTO or light 80
34 litres to top mark
27 to middle mark
17 to lower mark
(with dipstick screwed in)
I would suggest that unless you have steep land, only fill to middle mark.

I have the same problem with water in my 5211 hydraulic fluid. But, I think I figured out where the water was coming from. If the rubber boot at the bottom of the gear shifter is gone (like mine), then any water that runs down the gear shift will go straight into the tranny.

I had a problem the other day where my tractor would stall if I put it in any gear, but it would go in reverse when the gear shifter was in neutral. While digging into the tranny to see what the problem was, I pulled off the gear shifter housing and realized that the gear shifter had 'jumped' out of the slots that select the gears. Easy fix, but while I had it apart, I realized that without the rubber boot, water and other crap can come right now the gear shift lever and directly into the tranny. Now that I keep the tractor inside when not in use, so I doubt I'll have any more problems.
