2030 3 point

Several days ago I posted a question concerning the three point on my 2030 that won't raise immediately when I move the lever. It works correctly some of the time but usually not. However, if I slightly move the hydraulic lever (svc) right after I've moved the 3 pt lever, it will raise immediately. Something is up and I'm not nearly familiar enough with the system to properly diagnose it. I do have the service manual though and can follow through the hydraulic circuits.

At the time I posted my question, Tx Jim responded and since I was traveling, I wasn't able to answer his questions. I'd like to do that now if he's still interested in helping me.

First, I have not checked the standby pressure. I think there is a procedure in the manual to do that and I will do that as soon as I can find the time. I will check today to see where I had left the L/D setting and get back here with the answer. You mention to look in the filler for spraying oil when the engine is running. What does that mean if there is or isn't oil spraying? I will do that this morning too.

I do appreciate your help Jim.

Thanks,
Wes
 
Spraying oil could indicate leaking o-rings on the valves that control 3 pt. Spraying oil could also be faulty valves in scv. On a closed center hyd system such as your tractor an internal high pressure leak causes extreme heat which accelerates seal damage. Checking stnd-by pressure is easy. Just get a 3000# gauge install a male hyd tip and plug into breakaway coupler. Activate control handle and read psi.
 
Thanks Jim. I will do that as soon as I can get to it. Since you had asked about the setting of the L/D lever, is there a best position for it, considering what I've got going on here?

As long as we're on this topic, the 2020 that I have will raise and
lower the 3 pt ok. When you do raise it though, the power steering
goes away. As soon as it is up, it comes back. I have checked the
pressure and it is as it should be when the 3pt is not in use. As
soon as you raise it, it drops to 0. It has a clean screen, new filter,
clean screen on pump, and not spraying in rockshaft. It has a HI-LO
shifter also.
 

Sounds as if pressure control valve on RH side by hyd filter is faulty.Where are you taking the pressure reading? Checking both trans & frt hyd pump with a flowrater would be nice. Have you tried operating 3 pt with the hyd hi-lo in both speeds? does your tractor have hyd ind pto?
 
I checked the pressure by disconnecting the line to the steering
column. It pops right up when the 3 pt quits moving. I haven't tried
it with the HI-LO in different spots that I know of. It could have
been in either position when I did. No independent pto.
 
It still appears that pressure(priority) valve isn't doing it's job of giving priority pressure to steering. What was stand-by pressure before raising 3 pt?
 


I'd suggest to check pressure control valve.

I'll check inside the filler today and see if I can dig us a gauge to check the pressure.

Is there a way to get a thread to come back to the top when making a new response?

Thanks,
WEs
 

Sure is a way. Switch to Modern view by clicking at RH top corner of this page. Responded to threads rise to the top very similar to the way cream does on whole milk. :wink:
 
It was raining today and the tractor was sitting outside so had to wait a bit.
I checked where I had left the depth control setting and I had it on L/D. I moved it to the D.
I had the tractor running and checked to see if I could see any oil spraying inside but looking in the fill hole. I didn't see anything, just a bit few bubbles way down - probably the return?
Any ideas??
Thanks,
Wes
 
No, I haven"t had a chance to find a gauge and test
that - but I definitely intend to. I"ll get back to
you on what I find.
It did lift slowly but since I haven"t been able to
use it due to the mud, I"ll have to wait a few days
to try it out again.

Jim: REAL cream rises to the top of REAL milk,only on the farm it"s produced at,By the "REAL" How now Brown Cow!!. "I could"nt resist commenting" :Double Wink: PS. And not in the processing plant, that Homo"s the milk.. LOL.

When I was growing up hand milking cows every morning/night "whole milk" as I previously stated was just like it came out of the teat. I'll guarantee you that you put some of that JERSEY milk in the refrigeration for a little while that the "cream would rise to the top" :wink: :wink:
