Adding Rear remotes

[glukowicz]

Yes I heard relief and I looked and PB plug is in. Today I removed hydraulic top link and it is fully extended. It will not compress to shortest length. I even tried with ratchet straps. So I believe valve is working but something is wrong with the top link. Any ideas?

I also installed this morning the pressure gauge at pump inlet of FEL and I can see pressures as I use FEL and 3 pt hitch.

This is just a double check. What pressure do you see when you activate the TIP cyl fully extended and held until the relief comes on? ?

On the remote, when you push the lever towards the valve body, that supply's fluid to the A work port, and when you pull the lever out of the valves body, you are using the B work port. Does the remote lever work any part of the T-N-T.

The hoses from the A1 and B1 work ports go to the Tip cyl. You may have A2,B2 for another spool.

How many work ports on your valve? Did you perhaps cross two of the hoses.

I believe work port A hose should go tho the base end of the cyl and B work port hose should go to the rod end of the cyl.

I haven't crossed the lines. However I did not know that the ports had to go to specific ends of the cylinder. So tomorrow I should try the configuration you describe. B port to rod end ans A port to the base. If that doesn't work I will , switch them to make sure the opposite doesn't work

I had to use the tractor and blade today so I switched back to the mechanical top link. Shouldn't I been able to push the rod back closed with the hydraulic connections on the cylinder unattached to any hoses?

It depends, some cyl are really tight. If you can get it to move, watch out for fluid squirting out.

 

[glukowicz]

On the suggestion of a tech at Surplus, I bypassed the FEL and used the line from the pump to this valve and the valve worked. I checked again and the PB plug is in the valve and the instructions say it comes installed. The 3 pt hitch which is downstream from this valve works. Before I put this valve on the 3 pt hitch was downstream of FEL valve and it worked. However as we both know, now that this valve is installed between FEL and 3 pt hitch everything works except this valve.

What if I installed gauge at the input of this valve? Would that give us a clue of the pressure coming from the FEL valve to this valve? Also could the PB plug be defective? Would the 3 pt hitch work if this valve wasn't getting adequate pressure?

glukowicz,

If you connected the valve in series, and it appears you have, as the 3pt is working.

If you put the valve in a tee ahead of the fel valve, it will tell you if any valve is in operation, and if it is relieving, and the pressure developed.

If you have fluid going through the remote valve, there is no reason that I can think of that you can not re-route the incoming fluid to the A or B port of that valve.

If you have a QD on the gage, and plugged it into the A work port and flipped the lever, you should see relief pressure. If that is a two spool valve, then you have 4 work ports that you can test.

Can you verify that the spools are moving in and out of the valve body?

The next time you are messing with the tractor, give me a call. I will send phone #via email.

 

[glukowicz]

Ok, the pressure at FEL on all work ports is 2250. However the 3 pt hitch is around 400 at work and drops back to 200 when 3 pt at full extension

 

[glukowicz]

Could I have used the tank line on FEL for input on new valve thinking it was the PB? If I did this would the 3 pt hitch still work?

 

[J_J]

With PB installed on the FEL valve, part of the end gallery is blocked off, so that the fluid from the cyl will only go to tank.

With PB installed, the fluid from the pump is flowing through this port to the next valve with valve levers in neutral..

If you inadvertently used the tank flow from the FEL to the input to the next valve, you would only have fluid when you were using the FEL cyl.

If you ran the PB to tank, the pump flow just went to tank unimpeded.

There should be no fluid downstream with the FEL valve in neutral.

You know the remote valve works because you checked it out using the pump flow directly.

So the problem has to be hose routing.

This is the most probably routing.

Pump out/pressure port, FEL IN port, FEL PB out to remote IN port, remote PB out to 3pt. All tank hoses to tank.

 

[glukowicz]

Well, I looked again at all the plumbing. Everything seems right. The only thing that possibly could be wrong was the tank and power beyond lines being crossed. So even though it does not make sense, I tried switching those lines and everything now works. How the 3 pt hitch was working being downstream from the FEL and the remote valve is a mystery.

Next project will be to install a cylinder on the bush hog blade for angle and offset. The offset will be easy but the hydraulic angle I will need to get some welding done to accommodate the cylinder. Also i will need to figure out what cylinder to use.

Thanks JJ for all your help. I am not sure how I would have gotten this far w/o your help. Sure has been a learning curve.
