Ford 1710 three point will not raise

[hawkone115]

Got curious when I read another thread about sump filters. I am posting another picture because I am curious if this is an inline screen filter inside the rubber hose? Thihs line also goes into the hydo filter on the left side of the tractor. I imagine this is the suction side since there is a rubber hose between the two steel lines?

If the loader and PS are working the pump is good. You could still have some air trapped in the system. Do you have a valve by the foot rest that diverts the fluid to the loader or the TPH. If you do this valve has an adjustment so that you can increase the flow to the TPH or the loader. When was the last time you used the TPH.

I was reading on another thread when someone mentioned a screen filter? This line goes from what I believe is the suction side of the pump from the hydo filter. Just curious if anyone knows if there is a filter screen inside the rubber hose? BTW, the picture is sideways needs rotated so rubber hose is actuall vertical to the piping.

Hi Bill,

I used the TPH less than a week ago. Showing my son how to drive tractor we dropped the blade on the back to load firewood in the FLB. Went to raise rear blade no go (freaky).

I will post a picture of the diverter block. I was thinking the same thing, but since this is a pdp pump, I find it hard to understand how air would be trapped. As a side note, I went out about an hour ago to check the rear hydro vent. I raised the cap and heard a slight hiss of air. hmm very slight air release, so perhaps there is air in the system? I am trying to address all the simple stuff first.

I just posted another photo of a rubber hose attached going to the pump wondering if I missed cleaning or replacing another filter?

If the adjustment is there on the diverter block I will try it since I don't beleive I can hurt anything? I also saw on the bottom of the diverter a plug on the bottom, so I may take that off and see if the diverter has a screen or is clogged?

I forgot to mention earlier that I removed and replace a large bolt below the hydro filter just before refilling with fluid. It had sleeve on it with 4 ports but no screen...and very clean.

Thanks
Ted

Hi Sixdogs,

Not to my knowledge. It has a hydraulic filter ot the left side. My first thought was a sump filter but I do not beleive so.

I used to have a 1900 and a 2110 and am straining my memory but I had possibly had a sump screen as well as a hydraulic filter. It was under a three bolt circular cover on the side of the trans. Is there a way you could check with a parts dealer or look at a shop mannual or parts book? You will need serial number if you do.

Not sure if anyone mentioned it but I think there is a knob to turn under and in front of the seat--I think--that controls the rate of drop of the 3-pt hitch. It could be all the way open. Excuse my vagueness on this but I have owned several of these tractors and can't remember exactly. All were great tractors with zero problems which leads me to think you have a simple solution.

Are you in a cold climate?

Ted,

There is no reason to guess if you have hyd screen or not. I did go to NH website and verified that you don't have it. Familiarize yourself with the website below, put in 1710 as your model and check all that you want in reference to parts break down of your rig. If you have any other hyd system work such as your loader then your pump is okay and your flow is not getting to your lift spool or getting totally bypassed. Do you have any loader? does it work? Fiddling with the rate of drop button under the seat situated between your legs does nothing at all to raise lift arms. It only controls rate of drop, in other words if it it is totally closed (turning toward turtle) then you can not lower the arm. You need to establish flow by observing loader work or breaking the line on the discharge of the pump safely to verify it.

Hi JC,

Yep, I have a loader and it works quite well. The loader is a Koyker (although the hydraulics leak a little on the bucket cylinders need some new seals). I am going to take the check valve out on the left side of the piston head and move the lift arm up to see if I have any flow at all. Two springs and two steel balls as I recall seeing in your post. And yes my intention is to find a place to disconnect the discharge line once I determine where that is past the rear of the diverter block going to the loader. I did have fluid in the piston before I took it apart yesterday. If it is warm enough tomorrow I am on shift today. I may try some steps inside my (thank God) heated garage tomorrow.

First hail last night, thunder this morning with rain, then snow and wind, now sun is out setting in west. All we need now is some lightning and tornadoes welcome to Kansas!

Thanks sixdogs,

The flow control knob has been turned both directions and I am aware it only controls rate of drop.

There is a rod that goes from the right lift arm to the control valve. Is this hooked up. This puts the valve for the TPH in bypass when the lift arms are all the way up. If it is unhooked and in the up position the control valve would think the TPH was all the way up and would bypass the fluid instead of sending it to the lift piston.
