[Farmall] 340 Utility hydraulics

[Mike Sloane]

I can only go by my own experience with my 340 
<http://public.fotki.com/mikesloane/farmall_340/>. I really think that 
you are going to have to just dump the fluid, if it is that badly 
contaminated with water. When I removed that plate, the original filters 
were still there, and they were just a soggy mess. The new filter 
assembly is a much better arrangement. If you can get the system working 
at all, you can run it dry for a minute or so (no more than that!) and 
work the valves to pump most of the fluid out. If a few ounces of the 
old stuff remain, I wouldn't worry about it. You can loosen the hoses on 
the rear lift and just let the fluid run out of the lift cylinder and 
blow out the front-to-rear manifold with air.

In my case, I don't buy Hy-tran because there are no Case IH dealers in 
the area. I just use "tractor hydraulic fluid" from NAPA, and it works 
fine for me. I buy a 5-gallon pail and use it with a bucket pump in all 
of my tractors (I have about a dozen). There are two kinds of hydraulic 
fluid at NAPA - one for older machines like the 340 and the kind for 
newer machines like skid steers. The correct one says something like 
"Equivalent to Case IH Hy-tran".
