Re: Ezee On loader on MF 135 tractor

The nice thing with the front pump, is that it has zero effect on what your lift and draft control are doing. That's one of the several reasons I suggested going that route. You won't need to mess with your draft or position controls to use the loader, and certainly not a diverted under the seat.

Front pump makes the loader system completely independent of the internal pump AND simplifies the hydraulic routing.

My draft control and loader are now totally inoperable. A leak has developed at the control arm for the lower links and I'm afraid I blew some sort of seal. I took the diverter valve off and ran the tractor with the pick up tube stuck in the hydraulic pump and worked draft and position control enough that I should have seen fluid feeding out. I am stumped but suspect I may have to find someone capable of replacing some damaged parts. I will pull the response control cover this morning as see if anything looks suspicious; you may well ask, " HOw would I know?" Good question; let's here it for perseverance. PS I got closer to uploading photos but they didn't make it.

Any idea yet as to what's happened?

Re: Ezee On loader on MF 135 tractor

I think I have it figured out. I had my return hydraulic in a port I had pulled a plug from under the seat up near the upper control arms. It apparently does not go to the transmission; so I was pumping fluid into the cavity meant for grease to the upper control arms normally accessed by grease zerts. I replaced the plug and tapped a new line in on top in front of the lift cover. The loader is working only partially; very slow to sometimes raise the lift arms on only forward push on the bucket curl. My new guess is the hydraulic pump is too small for my Ezee-On 2060 loader, which has four double acting cylinders. I am going to look into an auxillary pump set up from my local Massey Ferguson dealer 100 miles away.

Maybe we should all step back a bit and make certain the FEL plumbing is as it should be with a power beyond feature ( which is a $30 plug inserted into the FEL valve) which should be used instead of the diverter valve.

Could you advise why you are unable to post pictures. Don't know how which is where many of us were at one time?

I will send you a pm with my email address. Email some pictures and I will post them here for you.

How big is your return line? Can't possibly be as small as a grease zerk!

Definitely try to post some pics for us, we will be able to help much more.

Rather than going through a dealer, you can grab a pump from surpluscenter.com for much less money.

I have managed one photo to load to the attachments page, we'll see if it loads.

Now some photos which is a big help. Please try and answer my questions added to your photos.

I want to make certain I understand where the Diverter Valve gets its oil supply. Is it a valve made specifically for MF tractors and is supplied oil by being bolted to the transmission housing.
In your photo, one of the valve out ports has a plug in it. The lever selector is at that port's position. Does that not block the flow from the pump or is there more going on I don't see?
You talked of drilling and tapping a port into the transmission case. I assume the one I have marked is that one and if the hose was unscrewed, there wouldn jusst be a big void under that port?

Looking more closely at the FEL valve photo, is the actual valve behind what I am seeing on its side with the nut type thing I circled?

Re: Ezee On loader on MF 135 tractor

The diverter valve in the first photo is a May Hill three port out valve controlled by the placement of the handle. It can apparently serve three different auxillary valves. The line coming out of it goes to the P2 side of my nimco FEL valve, not the T2 side which Nimco customer service told me is the out side of the valve (I took to mean return).. They do not have manuals on the valves that they no longer produce. The line I tapped in front of the diverter is indeed to return fluid into the upper void of the transmission. The plug below the FEL line is not something I would know about.
I have pulled the FEL again because it would only raise intermittently with much hesitation and I am afraid of damage. When it was set to the supply port and I was giving it it's test the lever was extremely hard to move to a different position. It makes me wonder if the supply and return lines are backward and the pressure too great for smooth movement of the handle.

Re: Ezee On loader on MF 135 tractor

It looks like you have a PB fitting in the tank side and you have it plugged. If so take it out then plug it.

Re: Ezee On loader on MF 135 tractor

Still....

Don't give up yet! Because the number of MF135 forum members is low and none posting on this thread, it is taking us all some time to understand your tractor.

It will turn out to be something simple we just have to figure out what.

I went back to your first post again.

I have a new after market May Hill diverter valve with three ports and a handle that conveniently indicate which port you have open because the handle seems to match the hydraulic oil diverter hole on the interior shaft. That to me means each of these three locations are supplies to auxillary implements. That also tells me that the return from a loader for example should be piped to one of the plugs that are in the upper part of the transmission housing on my MF 135.

Now I have it in my head that you ordered and installed the May Hill valve so you installed the pipe plug with teflon tape on it too. Is this correct?
The valve lever in your photo seems to be past the port with the plug you screwed in. Is this another position for the May Hill valve lever?


Could you easily remove the valve and then photo where is was sitting on the tractor immediately after you removed it. Also photograph the sides of the May Hill valve we have not seen in you photos.

Did the valve come with any instructions which you could post.

Did you have to remove anything in order to bolt on the May Hill valve?

In this next photo I have drawn a circle around an Allen wrench style plug in the transmission and just below the May Hill valve.

Because of its style and location it leads me to think somehow it is part of the hydraulic system.
