850 Ford - Loader Hydraulic Fluid

I posted a message yesterday about the hydraulic level for my front end loader. It is exactly like the photo submitted by Jim Walsh on his 841 Ford in the Photo Section of Yest. Tractor. Could anyone tell me if the fluid reservoir is the square tube that runs from the front of the tractor to the vertical uprights. If so, should this square tube be full of Hydraulic Fluid. I cannot check it the way I was informed yesterday.
 
How about tracing the hydraulic lines that feed the pump and the return to the resevoir? Do you have a front mounted pump that runs off the crank? Or, does your loader run off the tractors hydraulics?

If you have a pump, trace the line at the pump back to its source. This should be the bottom of your resevoir. The output should go to the controller. Then trace the return from the controller or filter to its final destination, this should be the resevoir. Most likely the resevoir is in the upright of the loader frame unless there is another resevoir installed. Or, unless it runs off the tractor hydraulics.

Once you find the resevoir then you can check the fluid. You should have a filler cap. A picture would be or great help. I searched the Tractor Photos, but could not find the tractor you mention, so, as Soundguy says a link would help.
 
I would if I was that computer literate. If you don't mind, click on Tractor Photos in the Galleries Section of Yesterdays Tractor, just to the left of this forum. Go to Ford and you will find 3 pictures of the 841 with loader. I was told that I could check it through the breather cap on the top with a yard stick. The breather on mine is on the round brace that the Lights on the Photo are on. Its only 5" deep. There is a 3/4" nipple on the square tubing that goes from the Front to the upright with a cap that can be unscrewed. It is a front mounted pump

There was thread from June of 2008 that asked the same question and had some clearer pictures of the same loader, filler tube and vent. The owner identified the frame as being the resevoir. The 3/4 inch nipple appears to be the filler tube. I would suspect that the resevoir consists of the horizontal frame and portion of the upright it is welded to. The vent being welded to this same upright. I would also suspect you would find the input line to the pump and the bottom side of this upright. The oil level could be filled within two inches or so of the top of the filler tube. It would seem to me that is where you would check the oil level. For comparison, my Davis loader uses about five gallons of oil. Hope this helps.
 
You remove the breather and fill it until hyd fluid is in the round cross bar under the breather.

Now that's funny, Mr One-Arm-loader-Man!
 
I found the discussion on June 16, 2008 and the picture shows the exact loader. The filler tube is in the same place. There is a tube from the filler tube to the valve body where the controls are located. I will fill to within 2" of the top of the filler tube. That will put the fluid about 1" above the tube leading to the valve body. Thanks everyone for your help. Sorry about not being computer savy.
 
Hey ROADMAN,
I'm getting behind on my reading and just found your question. First, look on the outside of the left main upright where the hyd cylinder mounts should be a metal tag that has model number 19-201, also known as Ford 703 loader, your Ford/New Holland dealer can use either number to order the operator's manual for around ten dollars. On page 17, Filling the oil reservoir, proceed as follows:
1: Remove the reservoir filler and breather cap(on the pipe that the lights are mounted on) and the oil level pipe cap (that 3/4 inch unit that you found in front and below the control unit). Fill the reservoir through the top breather cap hole and watch the level through the hole where you removed the oil level pipe cap. When the oil is visible in the level pipe it is full, re-install the pipe cap(I just pour it in slowly until it starts to overflow and stop).
2: Submerge the breather cap in hyd oil to saturate the element and install.
3: Operate the loader for approximately fifteen minutes at 1200 to 1500 rpm to properly bleed all air from the hyd system. Check the oil level after bleeding the system.
The loader unit oil capacity is approximately six gallons and can be drained through the drain plug at the bottom of the front guard.
The 703 series loader was made fron 1/59 to 12/71.
It's well past my bedtime so I hope my foggy brain didn't forget something important. These instructions are for a newly installed unit without any oil, but applies to topping up your existing unit.
