New Remote Valve Not Working--Need some help with troubleshooting.

[npalen]

That was it, JJ!!! Put the hose in the filler port and the cylinder cycles both directions. I owe you a beer or a couple dozen. Thanks.
I may have to put an adapter on the filler port and just attach the hose at that point. The only bad thing is that oil is going back to tank without being filtered. Don't understand why the tee in the return line doesn't work, but I'm not going to fight it.
Now, on to the next issue that I hope you can help me with also: The cylinder is 3.5" bore which figures 7.068" of area times 8" stroke is about 77 cu. in. It's taking 18 seconds to extend the cylinder rod the 8" which figures out to 256 cu. in. or a little over one GPM. I hear the tractor relief valve going off during the cylinder extend. All the lines and QD's associated with the added remote valve are 3/8" including the return to tank. I'm thinking 3/8" should be more than enough to handle the full 6 GPM but there is obviously restriction somewhere. It's getting a bit late so will sleep on it for now.

Edit: Should read "The cylinder is 3.5" bore which figures 9.6" of area...."

Edit II: Wonder if the hydraulic return filter is plugged enough to cause back pressure? That might explain why I was getting oil out of the second tank port on the valve when the plug was removed and then the tractor started. Full pump flow was backing up into the valve and causing the "weird problems" as you mentioned above?
Gotta get some sleep now.

Just pushing the rod in and out, will not develop very much pressure.

You must be causing something else to develop the pressure. I believe your relief valve is on the hyd block.

I would highly recommend a 3000 psi hyd gage in a tee in the IN port of the first valve.

You can use it to monitor and trouble shoot the hyd system. A flow meter and gage, relief valve and needle valve is the ideal setup.

Here are some hyd gage from TBN members.

Do you have a return filter or a suction filter.

Most hydrostatic transmission have a suction filter.

It should be the same as your B9200, JJ, which uses a strainer in the transmission sump where the suction line attaches. The return filter is on the left side next to the seat under a sheet metal cover. I'm going to order a replacement filter (32701-37950) from Messicks tomorrow. I'm guessing the existing filter is plugged enough to cause the back pressure and malfunction in the newly installed rear remote valve. I bought the B9200 a year or so ago and don't know the filter change history.
I do have a test setup with gauges, one 600 PSI and the other 3000 PSI and a flowmeter. I had bought it used on Ebay a while back but need to switch out the flat face QD's on it to my ISO Series A.
Will do some tests and let you know what I find out.

JJ, thanks for your suggestion of teeing into the pressure line going into the new valve with a GAUGE! Bottom line to all this is that I had the pressure and tank lines reversed on the valve. What I thought was the PB coming OUT of the FEL valve is apparently the PB going INTO the FEL valve. I don't understand how that is but reversing the lines into and out of the new remote valve makes everything work exactly like it's supposed to. It also explains the silly things that were happening with the return to tank line.
Again, JJ, many thanks for sticking with me on this. I know it can't be easy deciphering all the info you get from folks with all the variations of terminology that we use. Would be much easier if you could be there "physically" rather than over the WEB.

While reading through this thread I was thinking the reversed lines because I had the same problem with a valve temporarily fed by a remote valve on my big tractor. The operators manual had the quick couples incorrectly identified. Switched the lever position (after a call to Surplus Center) and everything worked as expected. That valve is now plumbed permantely.
