Zetor 3340
Hello I have a 3340 issues that I can’t seem to figure out. It continues to get water in the hydraulics everytime it rains. I have replaced the shifter boots thinking that could be a place for water to seep in. Is their somewhere specific I should be looking?
 
I'm guessing you don't have a cab? I have never seen a Zetor without a cab in real life only a vintage 3011. The only place I saw water in hydraulic oil was where the air breather on the return was allowing water in, but it would be only a little few drops. Or if the dipstick wasn't properly tightened.
 
The gearbox ventilation is in the form of a 5mm hole directly in the rubber of the gearshift lever sleeve of the main gearshift lever.

Regardless of whether you have a cabin or an open station - it is better to at least put the tractor under a roof, otherwise you will never be able to avoid such problems 100%.
