Massey Ferguson 1740M Hydro: LOSS OF POWER when hot!

IV drip bag fuel....
ok that phrase is just full of awesome sauce.

Dave, you know what I mean -- connect an improvised container with a fuel line direct to the injection pump inlet using gravity feed -- thus bypassing any and all other fuel line/filter/tank/lift pump, etc. possible issues. Would need to be a sturdy enough "IV drip bag" (hospital room terminology) to stand running the tractor around for an hour or so. May not reveal much but cheaper to try than a new turbo.

So I wonder if there is a way you can confirm the turbo is acting up without a laptop?

I think I know what you mean but what does a laptop have to do with it? Is there a socket on newer tractors where a diagnostic tool can be plugged in to check error codes? I am advocating that there SHOULD be such standardized sockets/wiring on all new tractors (my inputs to the USDA) but they do not already exist do they? Even if they did, plain laptops are not usually used, at least in analogous automotive applications. Test tools with attached plugs to fit the harness under the dash are usually used.

I had a friendly cat almost kill me in 2020 due to a cat bite so the IV drip bag resonates

Holy cat ! I mean Holy Cow!

All common rail injection engines will have a communication port, most are CAN bus and proprietary.
Also most common rail injected engines are designed for a bit more fuel pressure then gravity feed to the high pressure injection pump.
Some turbos will be ECM controlled for boost.
A laptop with the proper software can monitor an engine watching fuel pressure and flow and timing as well as turbo boost.

Great thread on what seems to be the same exact problem, and I thank you so much for finding this (not sure how I didn't, but way cool!). Only thing is the OP never replied back that it was actually the "fix".

Here's his last post....

Yeah, it is disappointing that he didn't post back but I'm guessing if it hadn't fixed it he would have been back on there saying as much, just guessing though!

I'm certainly not advocating that the turbo should be the next item to replace, at the tune of $1,800, but just a consideration.

If I knew that would fix our Massey, it would already be on order though.

While we re in a lull here, I had occasion to price a replacement turbo for my 4 cyl Perkins in a MF2660 last Nov. the MF dealer price was $1643 but a rebuild could be had around half that price. Of course the Chinese offerings were wildly scattered from $300 on up. Somewhat academic since the OP machine is still under warrantee. May matter a lot to Yander though?

I used a remote gas supply jug left over from my previous life as a motorcycle shop owner. 'plastic' jug with a fuel tap on the bottom and a fill cap and hook on top. Worked great.

Your turbo charger is too expensive for AGCO company to throw that guess at the problem. On the other hand, we do not know what all THEY know about the total population of tractors with this disease. Just as a tech issue (independent of the $ advisability of trying a new turbo) I am puzzled by how a turbo would wait 40 minutes to do anything (or less time under heavier load.) I'd certainly try the "IV drip bag fuel source" first. Might be something floating in fuel tank or lines that takes a while to clog (?) Maybe fuel flow quantity related? Any answers so far seem far fetched which is why this whole disease is so baffling.

Anything is still possible, but to me it sounds hardware related being that we now have other owners popping up with the same power loss and it's a delayed response with them as well.

I originally thought and remarked here in this thread that I was thinking injectors.

Turbo (to me) sounds acceptable and it sure could be heat related?: 1) Wastegate not staying shut when hot 2) Actuator not being able to hold pressure when hot 3) Boost controller leaking when hot 4) Shims/bushings/bearings heating up and dragging down air intake or basically making it naturally aspired which this engine is not tuned for.

It's all still a crap shoot TBH, but we have ruled out a few things. And, If my dealer wants to do a fuel bypass or IV bag as some have said here, I would say "why not!".
