Ford 3000 hydraulic problem continues

[TheOldHokie]

What kind of pressure should I expect when I put a gauge on the coupler 1500?

At least 1500 PSI.

No I’m thing the relief pressure should be around 2400 psi or a little higher, but not over 2800
I’m not near my books at the moment

Edit: took a minute to go look
Min pressure to off seat the relief is 2100 psi
Full open relief pressure is 2550-2650 psi

Thanks I will get it checked out in the next couple days

 

[1974vette]

I got the hydraulic pressure checked and all read out at 2300. The loader was lifting then settles down immediately so I am sure the cylinders are bypassing.
I will get them resealed and report back.
Thanks everyone for the help.

I am not as sure about the cylinders as you are. I suggest you test them using the procedure I gave you earlier in this thread.

I put the loader down. Unpinned the rod end of the cylinders both sides and disconnected one hose at a time and nothing happened as I worked the hydraulic lever . Base end is a bit more difficult to disconnect . So now I’m back to coupler problem?

I dont understand what you did. The test only involves one coupler

Disconnect base end coupler at valve and move lever to retract. If one of the cylinders is leaking it will extend. If nothing extends the cylinders are not leaking.

I disconnect one coupler and tried to move the cylinder with the hydraulic valve then rebooked and disconnected 2nd coupler and did the same nothing happed. Cylinder didn’t move. Hopefully that makes some sense

It does not make more sense to me.

Very simple - disconnect just the base end coupler. That is the only one that matters.

Then move the lever to retract - that is the only direction that matters.

Takes less than a minute to do the test.

I did that and nothing. I hooked the loader to my 930 case and loader works fine. The hydraulic valve on the bucket tilt will pop of dedent. the arms to raise will not dedent the lever and that lever “feels” different. To lower arms that lever will eventually dedent the lever.

Operation of detents is a side issue.

When you hook the loader to the other tractor does it goe up and down fine?

You also have 2300 PSI at all work ports of the loader valve on the 3000 and the loader does not go up or down when hooked to it?

Correct loader works fine on other tractor.
All 4 hoses off my ford 3000 hydraulic valves make 2300psi.

 

[1974vette]

I put on 2 new sets of couplers I had here.

And what?

 

[1974vette]

Same. So changed the loader arms to the bucket valve and it goes up down but a bit slow. Loader raise/lower won’t tilt the bucket, attempts to tilt but won’t. Check pressures again all are 2300,
I am really stumped

 

[1974vette]

Will the hydraulic remote temporarily do 2300 then fail? One remote valve works but is slow other won’t move the bucket or loader arms but will register 2300 on my gauge.

Appears something going on with that one valve. Hook the arms back to it then remove the rod end hose from the male coupler. Put the end of the hose in a bucket and see if the loader will lift.

It’s starting to sound like you have a couple hoses crossed or there’s a issue with the couplers
If you hooked the loader to your other tractor and everything works then there’s no issues with the cylinders

The ford 3000 hydraulic loader issue is fixed. After testing the pump and couplers and getting 2250 of pressure. I reved the tractor wide open and it would slowly raise the loader and when u let off the lever the loader would quickly settle down. I had the cylinders rebuilt and everything seems very good. Loader is fairly slow but I think that’s normal with this tractor and loader does not settle.
Thank you all very much for all the help and patience. I was getting frustrated with this little tractor. Thank you all again.

News flash - leaking cylinders wont retract under load.
