Changing hyd oil

PUTTER · Dec 12, 2013

I see lots of people on here having the same problem as me, water in the hyd oil on my Farmall 340. I pulled the 3 plugs to drain the trans and rearend, and drained the loader hoses and cylinders. The filter looked clean which was a plus, going back with new one. Is there any other places I can drain that would help get this creamy looking gunk out of there. When the weather got cold she quit working completely. I think i'll take the time to pull those covers off the bottum and fix some leaks while i'm at it.

I don"t know about a 340 but we had an old H that the top cover bolt holes were recessed and water would gather in them. Originally the bolt heads had copper washers under them, but if you didn"t put new washers on when you had them out water would leak down by them into the rear end and trans. Needless to say in the middle of January you weren"t going anywhere if enough water got in. I know from experience.

Copper washers, now there"s a good idea, I"m gonna do that. Thanks.

I put Permatex under the bolt heads on mine when I put it back together, and I still blow the water out of the recesses after washing it. I am going to move it this weekend after sitting for a long time, so I think I will check it for water.

"PUTTER"; Per the IH Preventative Maintenance Manual:
When the fluid has stopped draining, run the engine very briefly to drain the fluid from the pump and the connecting tubes.

FREEING THE SYSTEM OF TRAPPED AIR
Start the tractor engine and operate it at a moderate idle speed. With the filler plug or cover removed, slowly move the control handle or handles back and forth ten or twelve times through their full range of travel.
This frees the system of trapped air.
Then with the handles in the neutral position, stop the engine. If necessary add fluid up to the proper level in the transmission case, as instructed in the tractor Operator's Manual.

The top paragraph is different from the Farmall and International 460 info where the coil wire is removed and the engine is turned over a few times to clear the pump...as I just responded to a ? about a non-operative 460 hydraulic system. You must have gotten your loader retro-fitted to your Farmall 340?!

I disconnected the coil wire and spun her over Al and that got some out of the pump. I tried blowing the lines out with compressed air but didn't have much luck with that. I unhooked the lines to the fast hitch cylinder and lifted it with my shop crane and that worked to force the oil out of there. My Grandson and I unhooked those lift cylinders on the loader and I was expecting the oil to come out of the other fitting, got a bath. Yes I finally got the loader on and running, it has the manure bucket with the snow extensions and was modified by the PO. I think I will get good at taking it off because I don't like all the extra weight up front, steers hard even with power steering. Plan on building a more conventional bucket for it. I have changed the hyd oil before but never went through all the draining of the lines and cylinders, hope it makes a big difference. I hope to clean her up and paint her if I ever get a period of time that i'm not using it. Merry Christmas Lyle

Do the oil disposal places have a problem taking this water contaminated stuff? A search online suggested separating the water out. I would think that purifying the oil is part of the reclamation process and a little water will not hurt.
