I need to read things more carefully. I see now that using option 2 requires the outlet still going to the reservoir... and I was asking if it should be plugged. I need option 1 for the one valve and option 2 for the other. Now let's hope the supplier can get both.

I understand that but just trying to point out that all the valves, as is, are closed or as you say oil would be flowing back to the tank all the time when nothing is activated. I'm just showing how it is now. So, wouldn't both "CC" plugs need to be replaced by something? Or a different...

And besides that it looks as if you can only buy rods for 10 spools. Yes K5lwq, the mill I have is similar but has more features including an edger maybe? I'm wondering about the yellow cord/line/hose/tube going to the carriage. Or maybe it's blade lub or air?Could that have something to do...

950deerehunter has an interesting idea but even if it would work it would be an enormous task because of how the valves attach to the saw. Do I have it straight now. I have to use the down port because both valves can't be made strictly open circuit? The part 660280001 will replace the "CC"...

Please allow me to not include which of you made a suggestion or comment recently. I'm having enough trouble recalling. Yes, Woodland that went out of business years ago. Not the present Woodland that manufactures mills. Only one controlled function needed at one time. The engine drives the...

Hey, I'll take any advice and welcome it. Please someone try to explain to me the difference between a relief valve between the pump and say a stacked spool valve and the relief valve that is a part of the stacked spool valve (maybe wrong term)? They don't do the exact same thing?

Once again, please let me thank everyone for their input. In this case however the blade speed is directly proportional to the diesel engine speed and that can't be changed at random. There is something mechanical (cylinder activated) that moves the blade away from the log and idles the engine...

I feel I haven't been clear enough about one thing. When I bought the mill there were two hoses hanging out the end. I assume one went to a pump(s) of some sort. And the other one went to a reservoir I'd assume. The hose from the pump branched off to all three valves (three elbows) at once...

:) I must admit this is very confusing to me right now guys. I did look at the ends of both valves banks. Six spool "SVE22 Power Beyond Outlet w/ #8 SAE Beyond Port #10 SAE ORB (7/8-14 THD" and The nine spool valve with SVE21 "SVE21 Open Center Outlet w/ Conversion Plug #10 SAE ORB (7/8-14...

Update. The end plate on the six spool valve bank has SVE22 which the doc oldnslo referenced says is "SVE22 Power Beyond Outlet w/ #8 SAE Beyond Port #10 SAE ORB (7/8-14 THD" Does power beyond imply open??? The nine spool valve has SVE21 "SVE21 Open Center Outlet w/ Conversion Plug #10 SAE...

Really, I do appreciate all suggestions but I haven't tried many . One thing I did figure out this morning however is that the controls are indeed made by Prince. SVW1BA1 "parallel circuit construction" Hmmm.

Gosh, thank you. Great examples. Unless you or someone else thinks I'm way off base I should be trying for what's in figure 2-4? Only I don't have a separate relief valve now. What's confusing me a little/lot is the separate relief valve when there is also mention of adjusting the relief...

Wonder if carriage position motor control could be move here? Connecting the two valve stacks would be quite easy. But then I still don't understand the relief thing. If pressure builds up too much the relief allows fluid to flow though the valve stack to the tank... even as something is...

I see there have been posts I haven't seen. Someone asked I think if I had some sort of program maybe. I don't... whatever it was. I can't seem to find that post.

A lot for me to digest from you guys. Let me say this right now. When this mill was manufactured I'm guessing a gear pump was used and mounted somewhere on the "carriage" and driven by the Kubota engine that's there now. Remember I'm guessing a little here. Later someone changed things and...

Thank you. Thank you. I think I get what you mean. If I could change things like in my new crude drawing with fluid flowing from control to control in series with appropriate changes it could be open? And the vibration and noise would go away. Or connect the hoses for the motor in the top...

I certainly agree in that I need to figure out things before something is ruined. I only used a gear pump because a guy with a similar but newer unit uses a gear pump too. I guess it could be just a pressure relief vibration since I don't really know what cavitation sounds like but it just the...

Thank you everyone who is putting up with me. I can't answer that last question today I guess. I really don't understand what is meant by "a power beyond". And maybe it's cavitation like some have suggested too? "Cavitation occurs when the volume of fluid demanded by any part of a hydraulic...

If I understand it correctly the double acting control valves (two sets of 6 spools) are open center? As I said early I just assumed the oil would just flow through without any restriction when the control lever was in the middle position. Maybe I have that wrong? Or is a relief valve a part...

I bought an old no longer manufactured saw mill that had sat around for several years and needed most of the hydraulic hoses replaced. The hydraulic pump wasn't there and so I had to purchase that. I have to admit there was some guessing here. I'm only used to hearing the hydraulics on Farmall...

Wondering if anyone has ever had this issue... the hydraulic pump sounds just fine when either a cylinder or hydraulic motor is activated but when neither is activated the pump makes a bad noise and the suction hose vibrates? I'm of course baffled. Any ideas?

Hello. It appears that I'm just not sharp enough to figure out what's wrong and if I'm looking correctly the troubleshooting section doesn't show one particular knot problem. The outside twine ties correctly at least ninety nine percent of the time but the inside twine only ties correctly about...
