Ford 6610 3 pt arms well not raise

Hello, I am new to Yesterdays Tractor, but have viewed the forum's for sometime. I have a 1990 Ford 6610, Series 2, 2 wd, with Q cab. The tractor has 1678 hours on it. It has a weterndorf TA26/27 Loader on it. The tractor has one single Hydraulic Remote. Up until a week ago the 3 pt worked fine. I had hooked a disc up to do some discing, and utilized the Hydraulic remote to trainsport the disc. While using the Disc I did notice that the disc was raising and falling somewhat slower than previous time. I tried adjusting the Flow Control up and down, resetting the draft location etc. No good. Once I finished discing, I went to hook onto a 3 pt. cultivator. The tractor would not raise the cultavator. With nothing hooked to the 3 pt the arms raise fine, and atay up not drafting down. I have tried with the Loader Hooked up and unhooked. The loader is plumbed into the Valve Area that is normally mounted under the seat if there was no cab, on top of the trainsmission housing. 2 hoses run from this to the loader valve to supply it and not tie up my oly set of remotes. There is a small app. 1/8' steel line that runs from this Area under the seat to the remoted. I removed this and blew out, and observed that Hyd Fluid would be blown from the Valve remotes when worked. I cannot find anyother reason for this not to be working. I Need HELP, from someone with a knowledge on these matters. I am a fair Tractor Mech., but understand still very much learning. Any help to this ole farm boy would greately be appreciated. Thanks. Ken

OK... some things you neeed to sort out here.

1.Does the tractor have the second pump mounted on the rear of the engine on the left side?

2. The loader valve... does it have a supply line, a return line AND a pilot line? Where does the return line go? Is the pilot line teed into the pilot line from the remote with a large rectangular fitting about 1"x2"x1"?

3. Does the remote have full pressure and seems slow or does it do nothing?


I suspect that IF you have the dual pump system and the remote/loader has pressure but operates slowly... I would say that the relief in the main pump has some dirt on the seat or the valve is bad.
You can look at the main pump and you will see a hex head about 1-1/8" in the pump body. Turn that out with the engine turned off and blow it out, check it. It's a sealed valve but you may be able to clean it. If you had a known good valve to stick in for a check it would be good...

Otherwise I suspect you're getting into the prioroty pack under the cab for a cleaning.

Rod, Yes the tractor does have two hydraulic pumps, I checked he pressure at the remote read around 2200 lbs, of preassure I believe. Not the greastest set up I have for checking. As far as the loader goes only 2 lines One from and one too, the Valve Chamber Assembly under the cab. The two lines are hard plumbed into the assembly with 2 quick connects. There is not a 3rd lineor pilot line. I have noticed under normal run conditions that the loader valve does get warm, but I fugured this was because of a Open center design with the fluid running through. As far as the Hydraulic Remotes goes, it seems to work fine, or did up until the last time I used it, and it worked then, it just seemed to work slower. The Priority Pack you mentioned is where the 1/8" line comes from, and goes to the backside of the remote's. I think it is a type of bleeder line but not sure. I well check the Pump Body fittings when I get home, that is if I am not flooded out by the time I get back home.

Can you get a high res, well lit picture of the area where the lines attach under the cab? The more the better showing where everything hooks? What you describe... ~should not work~.... if I understand you correctly.

Please check back later when I get home I well get some pic's and post. Thank You so much Ken
