I give

[FL_Jerry]

Now I give in on my 2000bd power beyond setup return port issue (see previous thread for details). My question now is do I try to find an adapter to screw into the oil fill port or just have Koyker tell me how to make my joystick work like everybody else, i.e no seperate return, just the splice in the high pressure line. I might be able to splice into the low pressure side also for a return, but kind of worried about that.

Does anyone have any problems with the simple splice method such as the loader moving when using the 3ph etc?
I'm kind of leaning this way unless there is a big benefit to the seperate return for the loader.

Jerry,

I've watched and waited (hoped too) that the PB setup would work for you...but having done the same thing, with the same results, I figured I'd do it the way everyone else did.

I used the IN & OUT port spliced to two 90° compression fittings on the pressure line...NO return. It absolutely did NOT make any sense to me, but I did it any way.

The pump never strained, the 3PH operated flawlessly and the FEL never chattered, but worked smoothly and in unison while operating rear attachments (box blade).

It defies logic...but I have added a few more since, one with a twin lever control and one with joystick. No problems at all. You would think that it must have a return line (I did) but it isn't necessary as your controller just provides a continuos loop through the pump and into your original return.

If I'm reading your configuration right; it actually makes perfect sense.

What you're doing is putting everything in series. For open center valves this means neither is affected by the other at all when using only one. When using both, everything still happens at the same rate as if nothing else were on that line. The tradeoff is that, if using the FEL and 3pt at the same time your maximum pressure is divided between the two. In other words, if you have the max load in your loader, and try to lift anything on the 3pt neither will work, vice versa, and any total maximum combination thereof [situations you'll rarely have, so probably never notice].

If you went parallel, then the lighter load gets priority.

If you use the PB, you have a "prioritized" system, so if any spool on the first valve is wide open, the other valve block would be "dead". I should reread the earlier thread on this, but that's likely what happened.

Disclaimer: I am in no way an expert on this; so I'm probably wrong, but will admit it if so. /forums/images/graemlins/grin.gif

Thanks Mark, I'll get Koyker to confirm what I think I need to do with the joystick and forget the return line. They kind scared me away from this. The guy I spoke to said they had some complain that the loader moved when using the 3ph with the simple splice method so they did this PBY method. Do I need open center or closed center as I just found some paperwork from them showing different configs of the joystick?

BTW, I took the plugs out of the return ports and the opposite side(left) has a spring and a ball in there, a check valve maybe. The right is open. I think my testing shows that the actual 3ph control valve is being moved. I dumped the return into the oil fill just as a test and everything worked fine. Putting a T into the pump intake line probably would work too but going through that when the simple method works fine.....

Thanks for the support and help.

Interesting! /forums/images/graemlins/crazy.gif The only way I can imagine this is in the float position, but I'd rather have that "problem" then the downsides of either parrallel or PB.

BTW, I'm assuming open center writing this. Maybe Yanmars have closed; I'm betting open, but I know nothing about Yanmars or most compact tractors. /forums/images/graemlins/crazy.gif /forums/images/graemlins/grin.gif

yes, it does make sense. The problem is that the pressure applied from the FEL return line on the port below the seat causes the control valve to move, raising the 3ph. If this port were unobstructed, it would flow into the transmission without causing a problem. As far as using both at the same time, as long as the 3ph stays at the level I set it for, I think I'd be happy as I can only control one thing at a time,,,,I think that if you saw me trying to scoop dirt sometimes, you might challenge that statement /forums/images/graemlins/ooo.gif

I agree Chad,, Just took me a couple of weeks to realize it, lol
I studied the applicable sites (FEL installation) and was prepared to do it the only way I thought would work, the simple series method. When the Koyker instructions came for the 2000, it had this infernal extra hose.... I just had to make it look like their picture, lol.

Jerry,

What eventually made me give in was talking with the Sauer Danfoss company, then to another dealer who installs FEL for his Yanmars. What they said countradicted what Koyker stated...and Koyker is where I bought all of the fittings, hoses and quick disconnects.

I am still not certain that Koyker was wrong, but every attempt while using a fitting for a return proved troublesome. And after talking with Sauer Danfoss - (the company that made the controller), they convinced me that I was over complicating and I would have much better results with two in/out fixed points on the pressure side only. I have been able to drag with my FEL and lift my box blade at the same time...the system works only slightly slower, but together.

Good luck....BTW, I have 3 or 4 of those extra hoses laying around /forums/images/graemlins/grin.gif

Thanks Mark, again..

So, does the controller need to be open center?

Jerry

 

[mark777]

Yes, Well..pretty sure anyway. I haven't done any with a closed center.
