Update on Deutz 6806: ...

...As a side note, with all this draining, cleaning and adding of new fluid, my hands were soaked with 303 oil. Even after washing my hands several times, today, I have the softest, smoothest hands I've ever had in my life.

Your wife's going to love you!! :laughing:

Thanks for update. Good work with getting the third drain plug out. Leave the towbar off as I feel you have another 2 or even 3 full flushes to go, to get all the water out. Water is bad.

As was mentioned by CincyFlyer, you need to purge all the lines and rams.

Looking forward to more news. :drink:

Where is the power steering pump located if reference to sump or reservoir. I am concerned that the pump does not appear to be priming. Do you have shop vac exhaust or leaf blower that you could rig up to fill port on your reservoir to apply a slight pressure to the reservoir. Nothing more than 1 or 2 psi. If two people even having one person blowing in fill tube might be enough.

Continued running of the pump without fluid is not good

oldnslo, that is my concern as well. I did try air pressure last week when I drained and filled the first time. I rigged up a little plug that would fit into the transmission filler hole and connected that with my little air compressor. I pumped the system up to maybe ten pounds, (I'm guessing at this, but I was surprised when I pulled the plug, it felt like about ten pounds air pressure rushed out). Unfortunately, this did nothing to prime the pump. I didn't do it for long as I was by myself and was trying to do several things at once, (turn the steering wheel, balance over the seat and steering wheel while holding the air hose in the filler hole which is on the floorboard - in short, it was a very "un-natural" position and I'm not as flexible as I used to be). If I can get a few more "hands on the job," would you suggest I do this again? If so, how long? Should the tractor be running when I do this or can I do it without the tractor running?

The pump is located at the front of the motor, about five feet away from the transmission. A long pipe runs from the top of the transmission, (right under the seat), down at a 45 degree angle, then level along the bottom of the motor, then up at a 45 degree angle coming to the top of the pump. the pipe turns level for a few inches and makes a 90 degree angle into the top of the pump. The pipe looks to be about a 1 inch pipe.

Orangegroveguy,

What does the other line on the pump attach to?

Without knowing the type of fittings used on tractor I want to throw out a couple of suggestions that might help prime your pump.

1) depending on the fitting style can you disconnect the pump inlet line at the pump or at least loosen it enough to allow oil to flow freely and remove a possible air lock. If yes I would try disconnecting this line and then use a little air pressure to see if you can get oil out of this line next to the pump. Naturally do this with the tractor not running. Don't try this If this line cannot removed easily without potential for damage or creating air leaks.

2) Can you crack a fitting on the output side of the pump? Again you want a way for any trapped air to escape easily. Crank the engine over and see if any oil or air comes out of this fitting. If possible apply the slight air pressure to assist if forcing oil to the pump. Do not worry about turning the steering wheel at this time.

Be cautious on applying pressure 1 - 2 PSI should do the job.

Greetings and good day all you lovers of tractors and tractor things. As of yesterday, the Deutz 6806, (hence forth called "Big Green Ugly"), lives again! Here's what I did. I took the cap off a "Gatorade" bottle, drilled a small hole through the middle and inserted my air blower fitting from my little air compressor fitting through the hole. Next, I cracked open the lines to the power steering pump. Removing the transmission filler plug, I placed the "Gatorade" cap/air compressor blower fitting over the hole and applied slight air pressure to the transmission. Nothing. I applied more pressure. Nothing. I then cracked open the one of the lines leading to the "box" beneath the steering wheel and once again, applied air pressure to the transmission. Nothing. I applied more pressure, (perhaps up to ten pounds). Nothing. Each time I removed the cap from the transmission filler hole, air would rush out, so I knew pressure was building, it just wasn't going anywhere. I got a cup of coffee, sat down and did some thinking. Beneath the seat on this tractor is a metal plat held in place by in place by 16 13 mm. bolts. "Self" I said to myself, "I wonder what's under that plate." To remove the plate, I had to remove the seat which is held in place by 13 mm. four bolts. I took 13 mm. wrench in hand and started turning bolts. I was standing at the back of the tractor, removing the two back bolts when I noticed for the first time, that the seat on this tractor has a "John Deere" logo stamped on the back. I noticed as well that the frame the seat rests upon appears to be homemade. Whoever made it did a good job, but it didn't look "factory" made. Once I removed the seat, I saw that the top of the plate beneath the seat was covered in dirt, grease and oil. "Self," I said to myself, "if I don't clean that off, all that gunk and dirt is going to fall into my transmission." So I took an old paint brush, poured a little gasoline in a coffee can and started cleaning. That's when I found it. A plastic cap a little bit bigger than a quarter. I looked. I studied, I ponder. "Could it be?" Hesitantly, I unscrewed the cap and removed it. Sure enough, it was another filler hole, and the plastic cap had a little dip stick attached. I looked down into the hole - bone dry. I sat, I pondered. "Self," I said to myself, "this HAS to be where you fill the power steering." "Nothing ventured, nothing gained" I said as I fetched my last five gallon bucket of hydraulic oil. I added two and a half gallons of fluid, which brought the level up to the top line on the dip stick of my newly found plastic plug. "This is it." "Aren't I silly," "Why hadn't I found this little cap when I first started working on this thing." These were the thoughts that raced through my mind as I reinstalled the serat, certain and sure that within minutes, I would be happily driving "Big Green Ugly" over hill and dell. I cranked the tractor. Nothing. No fluid flowing, no power steering response. Nothing. I shut the tractor down, (I ran it for about a minute). I was sad. I sat. I pondered. Taking my 13 mm wrench back in hand, I removed the John Deere seat yet again. Then I removed the 16 bolts from the plate that sits beneath the seat and bumped it loose with my magic hammer, (it's the hammer I use to bump the starter in my Case when it won't start). I lift the plate from the top of the transmission and look inside. I see fluid. "Self," I say to myself, "the only way to see what's inside is to remove the fluid." I get a siphon hose and siphon the hydraulic fluid out of the area beneath the seat. Slowly it drains into a clean five gallon bucket. I watch and witness various things as the fluid level drops. There's a thingy one one side, another thingy back in the corner, a big thingy up front and lots of crud on the bottom. Finally, as the fluid is almost drained, I see a silver/grey thingy way down at the bottom, back in the upper left hand corner, (looking from the back of the tractor). This grey/silver thingy has a white plastic cap. On top of the white plastic cap is a spring clip. At that very moment, the solar eclipse passes overhead (seriously). I take that as a sign. First things first. I grab a roll of shop towels, (the blue kind), and begin cleaning all the crud out of this compartment. I use almost an entire role. Then I soak a few shop towels in gasoline and give the compartment a good cleaning, removing all the crud. Now the scary part. What will happen if I undo the spring clip? Will a spring with ball bearings pop out? Will something come loose that will be difficult to reinstall? Will a hydraulic demon grab me and pull me into the dark and frightening inner recesses of the machine? I remember the words: "Go west, young man." I think of the pioneers crossing mountains and deserts. I recollect Moses leading the people of Israel to the promised land. It gives me courage. I reach down and undo the spring. Nothing pops out. No ball bearings, no demon. I take hold of the plastic cap and start to wiggle. Out it comes, a long, plastic frame covered in gunk, as in totally and completely packed with gunk. "Self," I say to myself, "I don't think this is suppose to look like this." I take the plastic piece and spray it with the garden hose. It starts to come clean. I wash it in a coffee can filled with gasoline. It comes cleaner. I repeat this process over and over until it is completely clean. It's a screen within the system. A screen that was packed with gunk. A screen that is now clean. I blow it dry with my air hose and reinstall. I pour the hydraulic fluid back in the tractor and reinstall the plate. I stand at the side of the tractor. I look at the starter button. I feel fear mixed with anticipation. I press the starter button. The tractor roars to life with a symphony of cylinders singing their happy song. Within seconds, fluid sprays from every fitting I have cracked open coating everything within five feet of the tractor in hydraulic oil. Quickly I shut it down. I check the newly found plastic cap and dipstick which shows low fluid. I add more fluid, tighten all fittings, crank the tractor again. I reach up and turn the steering wheel. "Bump, bump, bump" and then, the front wheels respond - with ease. In less than a minute, I'm able to turn the steering wheel with one finger - WITH ONE FINGER! I cry tears of joy. I promise to fulfill all vows I have made to the gods of all things hydraulic. I shut the tractor down, reinstall the seat, (the John Deere seat with it's homemade frame which hid the little plastic cap). I crank the tractor up and start driving. I drive all over the property, up and down, back and forth, turning left to right and right to left. I make circles and figure eights. I drive fast and slow. I shift gears from low to high and back to low and all points in between. I am happy. A big thank you to everyone who gave guidance and assistance, help and support in making "Big Green Ugly" live again.

Not familiar with Deutz but would be very surprised if they run 80W90 for the hydraulics and power steering. I suspect hy-trans would be a better choice but again not 100% sure of this. If the pump is starving for oil & If their is enough air in the steering system then yes the steering wheel would spin freely. The stiff slow sluggish turning was from low oil volume being supplied.

I would strongly recommend you stop running this tractor or you may ruin the pump from lack of oil.

If you do change to hy-trans you will have to drain as much of the 80W90 out as possible. You may also have to change or clean the suction screens or filters if this model has them.

+1 with 'oldnslo'.

Tractors are like humans - They aren't meant to 'leak' fluids. :eek:

Drain the 80W90 out. It is incorrect.

Locate and remove the Suction Filter screen and clean it thoroughly.

Replace the Hydraulic Filter can.

Remove the Steering Ram and have the leaking seals repaired.

Reassemble and tighten hose connections.

Fill transmission with the Hy-Trans mentioned or something similar from your local tractor dealership. Not 80W90.

Start engine and cycle the steering wheel a few times and check for correct operation.

The "box with pipes under the dash" is the Steering Orbital" valve. It is somewhat complex. Ask PO if it is possible he carried out any work here involving removal/refitting of hoses whereby he may have fitted a couple in incorrect locations? It is not uncommon. Usually causes stiff steering or Steering Wheel becoming self-moving. :confused2:

:wrench:

Well, we were on the right track. :)
The presence of 'Gunk' and water as you described was a pointer. Suggest you take the time to repeat the oil change and flush/clean again in the near future. Gunk gets everywhere.

Enjoy turning your corners!!

:drink:

Congratulations on having the perseverance on getting the "Big Green Ugly" back in operation, Or in other words Stubborness will overcome common sense :thumbs:

A little surprised that the screen is that hard to access but then how many times in normal use do you need to access it??
