Rear Hydraulics

[DMF]

</font><font color="blue" class="small">( On the first picture, where are the two lines going?)</font>

Those lines go to my tractor mounted valve; in the second photo you can see one coming in the lower left hand side and you can just barely make out the second one near the top of the valve.

My dealer had told me to take the front line from that sump manifold, disconnect it from the tractor mounted valve and run it to my new aux. valve. Then he told me to take the return line from the new valve and connect it to the tractor mounted valve where I removed the front line. Does that make sense? /forums/images/graemlins/confused.gif

Your dealer is right on this. That is the way the picture that I posted has it. I know this is kind of confusing. The biggest problem here and in most threads like this, is that there are several different names for the same item. These different names are not always wrong, just different words used by different manufactures. BTW The T2 is a call return.

My valve and cylinder came in from Surplus Center last week. I am in the process of designing a bracket to mount the valve. My nephew came over this weekend to check everything out and order the fittings and hose I'll need. I'll post a few pictures when I'm finished. Thanks again for all the help.

Looking forward to seeing them.

I finally have my auxiliary hydraulic valve painted and mounted up. I’m just waiting for the fittings and lines. It’s a 3-spool Prince stack valve. I assembled it with the middle spool having a float option. I’m going to run two sets of lines to the rear (one of them being the float) and the last set of lines will run to the front.

Here’s a side view. I used existing holes on the fender for my bracket. The position appears to be pretty convenient for operation. The brass acorn nuts were added as the ends of the connecting rods stuck out beyond the nuts and I was afraid I’d be raking my arm on the threads when I rest my hand on the 3-point control. Hopefully we’ll be able to route the lines so it’ll look clean and still be out of the way.

Looking good so far. Did you make the bracket?

Yes I did. The plate on the fender is aluminum and the bracket going down to the angled part of the fender is some angle iron I had kicking around. I mocked up the plate out of 3/8" plywood first which helped me to fabricate the angle iron bracket. Then I transferred my plywood "pattern" onto the aluminum.

 

[JerryG]

I like to see good fabrication.

Well it poured all day Friday so work on my wall project stopped. My nephew came over and we got the valve plumbed.

Here is a shot of the front lines showing the QC's. I still need to make some brackets for the connectors. I am having issues with the fittings...They are Parker 3000 PSI version; FF-371-6FP (female) and FF-372-6FP (male) which are supposed to be very high quality. My problem is I have a real hard time (read impossible) to reconnect my dump trailer. It's always on the tractor end (not the trailer) that gives me a problem and only one side? /forums/images/graemlins/confused.gif

Very frustrating! I had to unscrew the connector and bleed some fluid to reconnect; not exactly a quick connect set-up! I must be doing something wrong?

Dump trailer in action!

 

[JerryG]

If the pressure is on the trailer side, make sure that you "turn the tractor off" and work the valves before you disconnect the hoses.

If the pressure is on the tractor side, make sure that you "turn the tractor off" and work the valves before trying to connect the hoses.

It appears that it is always on the tractor side. My nephew suggested this to me as well and it appeared to work when he tried it, yet I couldn't get it to repeatably work. It's strange because when I loosen the connector on the tractor side only a very small amount of fluid leaks out and it is certainly not under any pressure...? /forums/images/graemlins/confused.gif

Not sure what valves you have, but if you have the factory valves from Iseki that use levelrs thru the slots on the RH fender, there is a small screw you need to turn to set the valve to single acting. I am assuming of course that your dump waon has a single acting cylinder with only one line going to the cylinder.

 

[DMF]

No, I added a 3-spool valve from Prince (see one of my previous posts with the attached photos) The cylinder is a double acting with two lines...

I sent a request to Parker to see if they had any suggestions. No response yet...

Your Prince valve's mounting looks a lot like mine.

I have to relieve the pressure on the lines by stopping the tractor and moving the spool lever in both directions before I disconnect my dump trailer. I also have to do it for the snowblower.

A lot? I guess, it's quite alike!

MAD - I tried this as well (see my post above) but it wasn't repeatable, in fact it didn't work more times than it did work...
Any ideas? /forums/images/graemlins/confused.gif

More progress! I was at my BIL's machine shop last night until 11:00 working on some wagon repairs (posted in Build it yourself) and some brackets to mount the quick connect couplers to my tractor. (right now they are just wire-tied)

This photo shows them roughed out (my blueprint is in the back)

 

[DMF]

Here are the finished brackets. Two are for the rear and one is for the front (the one without the mounting holes as I haven't figured that out yet). The rear brackets will get paint and hopefully be mounted this weekend, yippee!
