[Farmall] 340 Utility hydraulics

[Jim Becker]

I thought the 340 hydraulics used oil from the transmission.  If so, you are 
looking at 5 or 6 gallons for a change.  Assuming that is so, I would pull 
the transmission/differential drain plug and give the crud at least over 
night to drain.  Then do a partial refill, enough for the gears and 
hydraulics to be able to pick it up, maybe a couple gallons will do it.  Run 
it around some to flush things and drain it again.  Repeat until the oil 
doesn't turn white.  I would use genuine Hy-Tran as it will absorb more 
moisture.  Using something else will require more flushes.

Then you can start working on the hydraulics.  Maybe clean oil will be all 
the hydraulics needs.  Otherwise, clean all the intakes, strainers, filter 
etc. and see if that fixes it.  If it doesn't, then you have real hydraulic 
repairs to diagnose/fix.  Once it is fixed, you will need to cycle the hitch 
and whatever is attached.  You will probably need to change the oil again 
and top it off.

I hate to say it, but sometimes if maintenance is deferred long enough, you 
need to catch up, not just pick up the schedule!

Subject: [Farmall] 340 Utility hydraulics

I bought a 340 utility gas with non working hydraulics. I pulled the plate 
for the filter and the oil was white. I know I have water in oil. What 
should be my next step? I hate to drain it and put in 10 quarts of Hytran 
and then have to do it again wasting the oil. any advice or test I can run?
