I looked in many places for a walkthrough for my particular equipment however I didn't find one that was 100% the same. Many tutorials and videos showed 80% similar steps but there were nuances that weren't the same, like the wire retaining clip. Eventually I came to a point where I felt I had...

I am getting voltage on the hot wire down there and when the PTO switch is on the return leg drops a couple of volts, which seems fine. However, I cannot confirm the solenoid is actually moving and opening the valve; I don't hear nor feel any movement, clicks, etc. :cautious: I intend to remove...

For more info, this solenoid is number 35 on the wiring diagram.

1533 SyncroShuttle PTO valve solenoid found. See this link. FWIW, dealer asking $316 (pre-shipping/tax)

To wrap up this thread with an answer, I've confirmed item 43 in the parts manual, above, called "Pressure Valve", is indeed the MF 1533 SyncroShuttle PTO valve solenoid. Attached are two pics of it, from above and below, and another pic showing easiest access, through the right-side access...

Given that 81 says "PTO pipe" and goes right to 36x, I think you're spot-on. TY for pointing that out.

Thanks ptsg. I was looking at that same diagram but it threw me because I don't see a solenoid, just the valve. If I'm following the lines right, looks like that's on the right-side, forward of the axel. Any more info on the solenoid itself? Thanks again

FWIW, this question branched off of this thread where I've been troubleshooting a PTO problem.

Anyone have experience to share (good) and/or pictures (better) on where this is located? For SyncroShuttle it's not the same place as the PowerShuttle. I found no reference of it (for SyncroShuttle) in the AGCO online parts guide. That guide does show the PowerShuttle solenoid but, again, it's...

DarkBlack, Are we looking in the same place? It looks like a useful part but not seeing it in the TOC for my model. https://parts.agcocorp.com/us/en/apbsearch?q=masseyferguson/651776/l&c=00-00&name=TABLE%20OF%20CONTENT

Yes, I have the plug; 'fluid change ops' were happening in that pic. I do not have whatever would be in the lower circle. Searching AGCO online parts book, the only thing called 'shroud' is at the radiator. Any other information? Would you happen to know where the PTO Control Solenoid Valve...

Following the wiring diagram in the Operator Instruction Book (pg D-27), I've verified voltage and continuity off the PTO switch, diode, ECU (in and out). The wiring gets lost in the bundle (cable assembly). Next check would be item 35, the PTO Control Solenoid Valve. What's most frustrating is...

Dmacleo, Great idea. Looks like the PTO solenoid is under the left floor, behind the frame :-( Hopefully there's a connector with easier access in the console.

Busdriver5097, I know this was a while back but I'm having same issue on my MF 1533. Did you ever figure your issue out?

bearthebruce, thanks. PM sent.

Dmacleo, The Operator Instruction Book says clutch is "single stage dry with 9.4 inch disc". Your description in lines 2 and 3 is same with mine. The PTO switch does turn on the dashboard PTO light, I'm not aware what else it does.

DarkBlack, you just made a point I'd not thought of before: The 'Operator Instruction Book' says the 1533 and 1540 should have 8.2 gal in the transmission but, that does not account for the extra fluid needed for the 1525 FEL. Looking around I haven't found (in this book or online) any mention...

I changed the topic to reflect latest symptoms (now PTO is the only issue). Bled the air (both sides of the pump and all of the cylinders) then ran the MF (pun intended) awhile. All ranges and gears check out. FEL does everything it should. 3PH - let's say I've figured out my controls and...

For anyone tracking this, I'm still working on it. I've gotten new oil (getting AGCO 821 XL from the local dealership was WAY cheaper than Amazon!) and filter (had to use ebay as dealer was out but ebay was nearly same price). I disconnected the FEL cylinders and flushed them best I could...

Would it be gravity or hydraulics to make it lower? I mean, with the FEL raised, if I turn off the engine and move the joystick, that releases the pressure and gravity takes over. Does the 3PH lower work the same? If so, shouldn't my 3PH lower (when eng off) too? Maybe the lack of weight on the...

Great point - reminds me something I forgot to add. I did confirm that knob was completely 'open' / 'out' / towards the rabbit (not the turtle / lock)

Seeing that fluid raises a couple of other Q's. I'm gonna go out on a limb and say the old stuff was contaminated. Assuming water was the cause (anyone have other explanation?), any tips on finding the source? I've seen no (downward) leaks. Could there be a spot above allowing water to seep in...

About the 3PH, I've highlighted in these two images (one is straight back view, other is from the side) showing the what I think are the raise/lower arms.

Apparently mocha latte will leave a stain on the sight glass. Besides draining all that fluid, is there a way to flush out the system (which might hopefully clean the glass)?

Someone put in mocha latte instead of hydraulic fluid.

Probably an important thing I didn't mention: this is a SyncroShuttle model.

Thanks. Have any links or more info on diagnosing and/or repairing that?

Update: Re-tested as suggested: with RPM at idle, I engaged PTO lever to 540, turned on PTO switch and saw no movement then nor all the way up to RPM at 540-mark. Re-tried 3-point raise/lower, no change. I confirmed it drives in all 4 gears in both low and high range. Looking closer at the...

New owner of a used MF1533L, year unknown, 599 hours. Engine starts easy and runs smooth but it has no power in the rear-end but Front End Loader works fine. With nothing attached on the back, RPM set to 540-mark, turning PTO on (and the lever either already in 540 or starting in Neutral then...
