Valve leak troubleshooting

[awesome]

I have this Vevor valve that I use for my rear aux.
The female quick connects are positioned verticaly, so facing up.

While operating the tractor, and without using the valve, I notice that the QCs fill up with oil. What this tells me is that the valve is seeping oil, and the 4 QCs also.

Would this point to all 4 qcs being faulty as well as the valve? Or is this just normal behaviour? In this case, how do people deal with oil messes over their tractor all the time?

Get a good set of QC's and you'll be a lot happier.
It will hopefully keep the cheap valve at bay.

Doesn't have to be a cheap valve. I've seen the same problem with Kubota valves and couplers. A male end with a pipe plug threaded into it installed in the couplers works too.

If those QC’s are facing up all the time, don’t they get dirt trapped in them?

I think that could be problematic.

Also, has it done it since "day one”?

Lastly, just out of curiosity, how long does it take to fill up? ……(I.E……seconds, minutes, hours, days)

Yeah, they are facing up but I put a plastic bag over them usually. I should get those rubber plugs though.

It has done this pretty much from day 1. They fill up within 30min I would say

Unless there is some sort of “re-build” kit available, which I would be dubious of doing, It sounds like you got “Vevor’d”

Don’t misunderstand me, I understand the reasoning behind getting stuff from Vevor, and I have ordered lots of Vevor stuff, but not all of it is/was “high quality stuff”.

Could you mount it vertically so that it would just “drip away” during use, then wash it once in a while?

 

[awesome]

Yeah, I'm fully aware that I should not be expecting much from Vevor. But I first wanna make sure that this is indeed because of vevor. If everyone tells me that it's completely normal to have oil all over a tractor all the time then I'll just let it go.

Couplers are positive shutoff devices and are not supposed to leak.

Spool valves are not positive shutoff devices and they all leak. Some leak more than others.

Do the couplers fill up to overflowing?

yes, they overflow.
I got the couplers from aliexpress BTW. So if buying good couplers solves this issue, then I'll buy a new set. But I won't bother replacing them if that won't do any difference.

I would replace one coupler and see how it does.

Vevor...
Aliexpress...
Problem?
See the connection yet?

Sorry. I have sever disdain for Vevor in particular.

Sometimes, it is expensive to be cheap.

Hydraulics is one of those instances.
